How is Newtons second law applied to football?
Answer:
More force from a football player's throw can accelerate a football faster.
Explanation:
Force = mass * acceleration
Final answer:
Newton's second law, stating that the change of motion is proportional to the force applied, is central to football actions like kicking, throwing, and pushing between players. The law explains how the force applied influences the ball's or player's acceleration, demonstrating the physical principles at play during a football game.
Explanation:
Newton's second law states that the change of motion of a body is proportional to and in the direction of the force acting on it. This principle is vividly demonstrated in football through various actions such as kicking, throwing, and pushing between players.
When a football is kicked or thrown, the force applied to the ball by the foot or hand causes it to accelerate in the direction of the force. The amount of force and the mass of the football determine its acceleration, according to the formula F=ma (force equals mass times acceleration). This is why quarterbacks and kickers need to apply significant force to throw or kick the ball long distances.
In the scenario of a lineman pushing against an opponent, each player exerts a force on the other. According to Newton's third law, these forces are equal and opposite. However, the player who can apply a greater force to the ground through their feet (thanks to friction and lower body strength) will be able to exert a higher force against the opponent, potentially overcoming them. This demonstrates that despite the equal and opposite forces, the outcome depends on the relative strengths and techniques of the players.

There are six forms of hypothesis. They are simple, complex, Empirical, Null. Altered, Logical and statistical. Relation between two variable predictions is simple hypothesis. On the other side complex hypothesis is the relationship between two or more variables.
How does the process of natural selection work?
Answer:
If I am correct it is when the weaker individuals or mutated individuals are killed of by other predators or by nature. Because they cannot survive this is natural selection because they are killed of by nature. Then if they are weak their species will go extinct, thus they are naturally selected to die and only the strong species remain.
Answer: The process by which organisms that are better suited to their environment than others produce more offspring. As a result of natural selection, the proportion of organisms in a species with characteristics that are given environment increases with each generation

When the Air Temperature is closer to the Wet Bulb Temperature then the Relative
Humidity tends to be
Answer:
the humidity causes moisture
Explanation:
Final answer:
Relative Humidity tends to be higher when the air temperature is closer to the Wet Bulb Temperature, because this indicates the air is nearly saturated with water vapor, approaching 100% relative humidity.
Explanation:
When the air temperature is closer to the Wet Bulb Temperature, the Relative Humidity tends to be higher. Relative humidity is the ratio of water vapor in the air to the amount of water the air can hold at a given temperature and pressure, expressed as a percent. Warm air can hold more water vapor than cold air; therefore, if the amount of water in the air stays the same and the temperature increases, the relative humidity decreases. However, when air temperature and wet bulb temperature are similar, it indicates that the air is nearly saturated with water vapor, and the relative humidity is approaching 100%, making the air very moist and potentially leading to fog or precipitation if conditions are right.
In regards to the Amoeba Sisters' video about blood type, if a man with Type A blood and a woman with Type O blood have a child that needs a blood transfusion, what blood type would not be able to donate to the baby?
Answer:
Explanation:
Donors with blood type A can donate to recipients with blood types A and AB. Donors with blood type O. can donate to recipients with blood types A, B, AB and O (O is the universal donor to all blood
A child born to a man with Type A blood and a woman with Type O blood cannot receive blood from Type B or Type AB donors.
When determining which blood types can donate to a baby born to a man with Type A blood and a woman with Type O blood, we need to understand the compatibility rules of blood transfusion.
When a man with Type A blood and a woman with Type O blood have a child, the child can have either Type A (AO genotype) or Type O (OO genotype) blood. In the ABO blood group system, individuals with Type A blood can receive blood from Type A and Type O donors, while individuals with Type O blood can only receive blood from Type O donors.
If the child needs a blood transfusion, they would not be able to receive blood from Type B or Type AB donors. This is because Type B blood contains B antigens that would trigger an immune response in the child with Type A or Type O blood. Similarly, Type AB blood contains both A and B antigens, making it incompatible with the child's Type A or Type O blood.
Therefore, when considering blood donation for the child of a man with Type A blood and a woman with Type O blood, it is important to ensure compatibility based on the ABO blood group system to prevent adverse immune reactions during the transfusion.

Impermeable land.Snowpack. Amount of rainfall in a particular area.Changes that may occur at the river water level due to high rainfall.Extent, duration, and intensity of storms that produce moisture.Information about the river drainage system, the temperature of the ground, vegetation cover in a given area, and impermeable land area to predict the severity of the floods.What benefits do plants with a smooth stem have? Does the stem type protect a plant?
Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.
The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.
Final answer:
Plants with smooth stems benefit from less resistance to water flow and reduced pest habitation. Modified stems like rhizomes, stolons, runners, corms, tubers, and bulbs aid in survival and reproduction, storing food and facilitating spread. Stem type contributes to a plant's adaptability and protection.
Explanation:
Benefits of Plants with Smooth Stems
Plants with smooth stems often have advantages in environments where there is fast-flowing water or frequent rainfall. A smooth surface can reduce resistance and allows water to flow off easily, thereby reducing damage from strong currents or heavy rain. Furthermore, a smooth stem can be less habitable for pests and parasites, which often find it difficult to grip onto the slick surface. From an evolutionary perspective, plants have developed different types of stems, including modified stems, to adapt to their environments and enhance their survival and reproduction.
Modified Stems
Rhizomes, stolons, and runners provide an advantage by allowing the plant to spread horizontally and produce new offspring at a distance from the parent, good for colonization. On the other hand, corms, tubers, and bulbs store food, which can be crucial for survival during periods of dormancy or when conditions are not conducive to growth. These modified structures often contain nodes and axillary buds, indicating that they are indeed modified stems rather than roots.
In summary, the type of stem can indeed protect a plant by aiding in its adaptation and survivability. Whether it's through physical characteristics like a smooth surface or modifications for storage and reproduction, the stem is a vital component of a plant's success.
Gastric lipase has an optimal temperature of 37°C. Sketch an optimal temperature graph below.
Answer:
See attached picture
Explanation:
An optimal temperature graph plots the rate of the enzyme reaction against the temperature. We know that the optimal temperature of this enzyme is 37C, so we know that at this temperature, the rate will be highest.
Additionally, there will be a minimum temperature required for the enzyme to work at all, which is why the line graph slowly increases the rate until its optimum at 37C.
Finally, at higher temperatures, the enzyme will become denatured and its activity will be diminished. This is why the activity drops at high temperatures and is non-existent at very high temperatures.
The speed of sound is the measure of how far it travels in a certain amount of time. The speed of sound will differ depending on which of the following?
A) The frequency of sound.
B) Where the sound originated from.
C) The pitch of sound.
D) The material the sound is traveling through.
Explanation:
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
Answer:
Option D is the correct answer.
Explanation:
The speed of sound refers to the distance travelled per unit time by a sound wave as it moves. At 68º F its speed in air is about 343 meters per second, or 767 miles per hour or a kilometer in 2.9 seconds. There are two big factors to be considered: first one is temperature and the material the sound is traveling through, so the last option is the right answer.

Explanation:
diffusion : movement of particles from a higher concentration to a lower concentration down to ge concentration gradient
osmosis: movement of water from higher water potential to a lower water potential through a partially permiable memberane
active transport: movement of ions from a lower concentration to a higher concentration against concentration gradient using energy from respiration
How do the random distribution of chromosomes and crossovers create more variation in the resulting gametes?
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Sexual reproduction results in genetic variation through crossing-over, independent assortment, and random fertilization, leading to a vast number of unique genetic combinations.
Explanation:The process of sexual reproduction is able to produce a significant amount of genetic variation in offspring. This variation emanates from three pivotal events: crossing-over, independent assortment, and random fertilization. Crossing-over is a critical event during meiosis where there is a reciprocal exchange of DNA between maternal and paternal chromosomes. This leads to chromosomes with a mix of genetic material from both parents, which are then passed into gametes.
Moreover, the independent assortment of chromosomes during metaphase I further contributes to genetic diversity. This occurs when homologous chromosomes align randomly at the metaphase plate, and each daughter cell receives a random mix of maternal and paternal chromosomes. Given that humans have 23 pairs of chromosomes, over eight million combinations can result just from this random assortment. This figure doesn't even include the additional diversity brought about by crossing-over.
Lastly, random fertilization amplifies the potential for variation, as the combination of one randomly selected gamete with another during fertilization results in a zygote with a unique genetic makeup. These mechanisms ensure that the likelihood of producing two genetically identical gametes is extremely unlikely, which plays an important role in the survival and evolution of species.

If you were to hike the distance from Point A to Point B, what would be the gradient of your climb?
Final answer:
The gradient of a hike represents the steepness of the climb. The specific gradient of a hike from Point A to Point B depends on the change in elevation and horizontal distance between the two points. In the given example, the gradient is calculated to be 13%.
Explanation:
The gradient of a hike represents the steepness of the climb. It is a ratio of the change in elevation to the horizontal distance traveled. In this case, if you were to hike from Point A to Point B, the gradient of your climb would depend on the specific locations of Point A and Point B, as well as the change in elevation between them.
For example, if Point A is located at 3440' and Point B is located at 3720' with a rise of 280', and the run is about 2200', then the average slope or gradient would be calculated as (280)(100)/2200= 13%.
Therefore, the gradient of your climb would be 13% if you hiked from Point A to Point B.

A creep.
B a mudslide.
C a rockfall.
D slump.
Answer:
Option C, Rockfall
Explanation:
Talus is basically formed along the side of a slope at it base by the deposition of pile of rocks and sediments which have eroded from the slope and have collected at the base. In a rock fall, the rock fragments detaching from a vertical cliff slides/topple down to the base of the terrestrial structure there by forming talus.

Which of the following accurately describes what makes a material a good conductor?
A. It must resist neutron flow.
B. It must readily accept electron flow.
C. It must readily accept neutron flow.
D. It must resist electron flow.
Answer: Option B
Explanation:
The electrical current is defined as the flow of electrons inside a material.
As more electrons can flow in a given time (for a fixed area, suppose the transversal area of a wire), more electricity is being generated.
Some materials have some resistance to the flow of electrons because they have "obstacles" that impede the free flow of the electrons, and when the electrons hit those obstacles, energy is liberated, this is why some materials heat up as a current flows throw them.
Now, you also may know that as the temperature of an object increases, also the kinetic energy of the particles inside of it, so the particles of the material will be moving a lot more, and because of this, the electrons will find more resistance to the motion.
The correct answer here is B; a good conductor must readly accept the electron flow.
Answer:
Readily accept electron flow
Explanation:
The answer is b. Readily accept electron flow. It is because electron flow is the reason for generation of electricity i.e, current is produced in the direction opposite to the electron flow. In order to behave as a good conductor, it must allow free flow of electrons through it. Hope it helps:)))

What is a method of making many copies of DNA
Answer:
The methods by which DNA molecules multiply is known as REPLICATION
Explanation:
DNA REPLICATION.-
In all living organism DNA replication occurs. IN replication DNA replicates in this way making its replica or we can say its copy.
During replication, both the strands of DNA are separated first. Then each DNA strand function as the template and makes its own copy to make the full DNA molecule. This is the SEMICONSERVATIVE mode of replication. In which each DNA molecule has one parent strand and one newly synthesized strand.
The replication start sight is ORIGIN OF REPLICTION( in E.coli ori c). At this location Helicase enzymes help in opening of the DNA.
The enzyme which has very unique function of adding nucleotide on the DNA strand and synthesizing DNA is DNApolymerase.
DNA replication occurs in 3' to 5' direction.

Are all plant structure and function the same? Explain
The plant cell is the basic structural and functional unit for all living organisms. .. So basically, the answer is yes. Plant cell structure is very similar to that of the animal cell, while the structures within each group the same throughout organisms. The two types of cells contain many of the same organelles. These organelles carry out the same functions in both types of cells.
Even though there are such a variety of plants, there are a few things that all plants have in common. At the cellular level, all plants are eukaryotic, meaning they have a nucleus and other organelles. One type of organelle in particular, chloroplasts, are found in all plants.
The map above shows the dissolved oxygen levels at various locations in the Gulf of Mexico. Aquatic wildlife usually is more heavily concentrated around coastlines and in estuaries where fresh and salt water meet. However, the map shows an anomaly to this phenomenon. What likely explains the dead zones around the coastline of the Gulf of Mexico?
Answer:
runoff containing nitrogen enters the Gulf from rivers, causing algal blooms and subsequent eutrophication.
Explanation:
Eutrophication is the reduction of dissolved oxygen due to an increase of algae, which subsequently die and decompose, consuming high levels of dissolved oxygen.
Which statements describe some ways that the student recorded data incorrectly on the lab report to the right?
A. The speed data should all be arranged in
increasing order.
B. No units are given for the speed of the water.
C. Millimeters are not the best unit to use for the
distance.
D. Wind speed should be in mph.
E. The student mixes units of length, using SI units for distance and customary units for depth.
The student recorded data incorrectly by omitting units for the speed of water and potentially mixing units for length and depth. Appropriate and consistent units must always accompany scientific measurements, and an understanding of both SI and customary units is necessary.
When recording data, it is essential that units are always included to avoid confusion and ensure precision in communicating the results. While there is no strict rule that speed data must be arranged in increasing order, it could help in some analyses. However, if the data does not include units for the speed of the water (statement B), then that is incorrect. The choice of millimeters as a unit for distance (statement C) depends on the desired precision and the context of the experiment; millimeters are a fine unit for short distances, but could be impractical for longer ones. Wind speed does not necessarily need to be in mph (statement D) as it depends on the regional or scientific standard; both m/s and km/h are also commonly used. Lastly, mixing SI units for distance with customary units for depth (statement E) can lead to confusion and should be avoided; consistency in the unit system is crucial unless there's a specific reason to convert between them. Furthermore, consistency is important when presenting data. It's crucial for students to understand both SI and customary units to effectively interpret and communicate scientific information, which includes being able to convert units when necessary. Therefore, the student must check their lab report to ensure that units are present, appropriate, and consistent throughout the document.
Explain the law of conservation of energy. Give a specific example using kinetic and potential energy that shows how energy is conserved.
Energy can neither be created nor destroyed. It is transformed from one to another form.
The example of potential energy raised ball over the round and example for kinetic energy is water is used for moving the turbine to produce electricity.
Explanation:
This process happens because of conservation of energy. According to the rule of the conservation of energy, energy can’t be created nor destroyed. It is simply converted from one to another form. It simply means this system always need same amount of energy.
Due to motion of object or particle an energy is formed is called kinetic energy and due to relative position of energy an energy is formed is called potential energy.

Based on the model explain whether the molecules shown crossing the membrane require energy to do so
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
Answer:
Read below
Explanation:
As a rule, molecules can either pass within the cell without applying energy throughout the process of passive transport (Molecules of oxygen for example). The molecules that are big and un-polar are unable to pass through the cell membrane easily. These molecules will need the energy to have the ability to go through the cell membrane. These molecules possibly might go through with the assistance of the carrier or facilitated proteins (Molecules of glucose for example).

What is the difference between the grassland and savanna biomes?
Grassland biomes are closer to the equator and receive more rain
Savanna biomes are closer to the equator and receive more rain.
Grassland biomes contain mostly grasses
Savanna biomes contain mostly grasses
Answer:
Savanna biomes are closer to the equator and receive more rain.
Explanation:
Biomes are large geographic regions defined by a specific type of climate pattern and certain dominant plant and animal communities. Both grassland biomes and savanna biomes contain mostly grasses. Grassland biomes are found in semi-arid climate regions, where the rainfall is not sufficient to support significant tree growth. Savannas are grassy ecosystems with a significant component of woody-plants like shrubs or trees. They are found closer to the equator because of their warm climate requirements. They have two distinct seasons; a rainy season in the summer with a good amount of rain and a dry season in the winter.
