The answer is 450nm.

The physical laws that govern Earth’s systems involve _____.

matter and energy

~Hope this answers your question!~

Answer:

The correct answer is option B, Matter and energy

Explanation:

It is not only the earth which is governed by the law of matter and energy but the entire universe work on this concept. As per the law of matter and energy, both the matter and energy remains constant. The matter is composed of atoms and as per the conservation laws it is neither created nor destroyed, thus the number of atoms in a matter remains constant before and after conversion from one form to another. While energy can also be neither created nor destroyed but its form can be changed from one to another.

Answer:

Wind is primarily driven by differences in air pressure. These variations in air pressure are due to temperature differences caused by variations in solar energy received at the surface of the earth. The sunlight absorbed by the ground depends on the latitude of the location, the slope and the underlying surface.

Explanation:

he Piranha is one of the most efficient predators on the face of the earth. Granted it is not a large animal, with most only reaching about 5 1/2 to 10 inches (14 – 26 cm), but it is known world wide for its ferocious nature. They have razor sharp teeth and are opportunistic carnivores.

A frenzied attack by a group of Piranha will set the water churning. They will attack and eat all sorts of aquatic animals, insects, lizards and amphibians. They will also devour rodents, carrion (dead meat), and sickly or weakened land animals that venture into the water.

The teeth of the Piranha are triangular in shape with an exact fit in their jaw, comparable to a bear-trap. They are designed to puncture and slice the flesh from their prey. They can strip their prey to the bone in a matter of minutes.

These fish are a great source of fascination. Their natural behaviors have become fodder for the scripts of moviemakers looking for a sensational twist to excite and entice an audience. What could be more intriguing than creating a 'fear factor' from the behaviors of these provocative fish found in the "wild". Yet just like the Great White Shark and the Anaconda constrictor, also popular subjects of thriller movies, the Piranha’s behaviors are over-fantasized.

The Piranha does engage in a feeding frenzy that will "make the water boil" if only because a hungry school of fish are trying to reach the same limited food source. All that activity is bound to create water turbulence. A Piranha school generally only consists of about 20 or so fish, but in a feeding frenzy it can reach up to several hundred..

Piranhas are not always that deadly. Many species live solitary lives once they reach maturity and only four or five species pose any significant danger. Piranhas rarely attack people. Many experts believe they are actually timid fish, and shoal for protection. Even the most aggressive are thought to be not really dangerous until they are trapped and confined, and then attack in self defense. As a pet they are fascinating and beautiful fish, yet you can't hold or pet them. They are not affectionate and owners must be extremely careful, especially when handling them. They do have sharp teeth and an aggressive/defensive nature. Most Piranha bites are sustained when the fish are being handled, though that's not to say a hungry fish is never dangerous.

The statement is accurate. Genotype refers to an organism's alleles or genetic makeup, while phenotype denotes the physical expression of these genes.

True. The statement is indeed correct as per the principles of genetics. The term genotype refers to the genetic makeup or alleles of an organism, while the term phenotype signifies the physical characteristic or outward expression of a trait that an organism possesses. For example, in humans, the genotype BB or Bb determines the phenotype of brown eyes, while bb represents the phenotype of blue eyes.

Answer:

A strike-slip fault.  

Explanation:

A strike-slip fault is a type of tectonic movement that follows an occurring fracture in a parallel manner. There are two types of strike-slip faults: dextral (right-lateral) and sinistral (left-lateral). In dextral strike-slip faults, the tectonic movement would move to the right – remember its location is still parallel to the location of the fracture in the earth’s surface. In sinistral strike-slip faults, it would move to the left.  

During an earthquake, under your feet, you might feel it as if the earth is moving towards either the right or the left.  

Answer: Reverse

Explanation: Reverse faults occur at plate boundaries known as convergent boundaries as a result of something called compression, where two plates push toward one another. Because of this, most reverse faults are located in areas near plate boundaries, mountain ranges, or subduction zones.

Bacteria. As I remember I’m sure it’s bacteria

Answer:

The correct answer is Bacteria.

Explanation:

Decomposers or saprotrophs are such organisms that depend on dead plants and animals for their food and nutrients. They help in decaying organic matter into various chemical nutrients essential for living organisms.

Bacteria is one great example of decomposers that changes dead organic matter into chemical nutrients like nitrogen and carbon that are released back into the air, soil, and water.

Thus, the correct answer is Bacteria.

25 degrees Celsius, as this is the highest point on the graph which means that the oxygen flow is optimal at this temp. Since oxygen is a product of photosynthesis, if more is flowing at 25 degree, more photosynthesis is happening.

Answer: D

Explanation: According to the graph, at 25 degree Celsius the rate of oxygen flow is maximum. Oxygen is a byproduct of the process of photosynthesis. So temperatures of 25 degree Celsius allow plant to photosynthesises more .

The correct answer is; D

Homologous structures is the term used to describe physical similarities between related species that indicates a common ancestry.

Homologous structures are structures that have the same form or functions in different animals, indicating that the animals have evolved from a common ancestor. Homologous structures usually appear very similar in form but it may or may not have the same function in the different animals that are suggested to be related. The bones in the front limbs of many different mammals (such as humans, deer and bats) which are similar in their structure and arrangement are homologous structures.

this process occurs in multicellular organisms. it is called programmed cell death or apoptosis.

The correct term for the process that occurs in autotrophic organisms is photosynthesis.

Photosynthesis is the process by which autotrophic organisms, such as plants, algae, and certain bacteria, convert light energy, usually from the sun, into chemical energy in the form of glucose. During this process, carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of sunlight. The overall chemical equation for photosynthesis can be represented as:

[tex]\[ 6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2 \][/tex]

This process takes place in the chloroplasts of plant cells, where chlorophyll, the green pigment, captures light energy. The energy absorbed by chlorophyll is used to split water molecules into hydrogen ions, electrons, and oxygen gas. The electrons and hydrogen ions are then used to convert carbon dioxide into glucose through a series of steps known as the light-dependent reactions and the Calvin cycle (light-independent reactions).

Photosynthesis is crucial for life on Earth as it is the primary source of organic matter for the food chain and is responsible for the oxygen in our atmosphere.

Answer:

Honestly I wouls say C.

Explanation:

The habitable zone, where Earth is situated, is defined as the distance between Earth and the Sun that prevents water loss but does not force freezing temperatures. Thus, option C is correct.

At room temperature, which can range from 0 to 100 degrees Celsius, water is found in a liquid state.

This is caused by the countless, small, weak hydrogen bonds that cling to water molecules momentarily.

All liquid water on the planet, which is necessary for life as we know it, is still present on its surface.

But where our Earth is now, in that disk, was far hotter when our solar system was originally formed.

Therefore, Earth has a strong gravitational pull and moderate temperatures.

A. The lighter wagon will move faster, since there is no change in force to make up for the increase in mass.

Final answer:

The lighter wagon, with the house cat, will move faster because acceleration is inversely proportional to mass, assuming the force applied is the same.

Explanation:

If the same person uses the same force to pull the same wagon carrying a tiger cub that has a mass of 20 kilograms, compared to pulling a wagon with a house cat that has a mass of 2 kilograms, the wagon with the lighter house cat will move faster. This is because acceleration is inversely proportional to mass when the applied force is constant. Therefore, if you apply the same force to two objects of different masses, the object with the smaller mass (the house cat) will experience greater acceleration, leading to a higher speed than that achieved by the object with the larger mass (the tiger cub).

Statements 2 and 5 are true for the cross illustrated by the Punnett square.

In order to determine which statements are true for the cross illustrated by the Punnett square, we need to analyze the provided information.

Assuming 'R' represents the dominant allele for smooth seeds, and 'r' represents the recessive allele for wrinkled seeds.

The Punnett square looks like this:

```

     | R   r

---------------

R | RR  Rr

r | Rr  rr

```

Now, let's evaluate the statements:

1. The F1 generation will be homozygous:

  - This statement is false. The F1 generation consists of individuals with both homozygous (RR) and heterozygous (Rr) genotypes.

2. The entire F1 generation will be hybrid:

  - This statement is true. The F1 generation is a result of a cross between homozygous (RR) and homozygous recessive (rr) parents, making all individuals in the F1 generation heterozygous (Rr) and thus hybrid.

3. The entire generation will have smooth seeds:

  - This statement is false. The F1 generation has both smooth-seeded (RR) and wrinkled-seeded (Rr) individuals.

4. The entire generation will have wrinkled seeds:

  - This statement is false. The F1 generation has both smooth-seeded (RR) and wrinkled-seeded (Rr) individuals.

5. 50% of the generation will have wrinkled seeds:

  - This statement is true. In the F1 generation, 50% of individuals have the genotype Rr, which results in wrinkled seeds.

In summary, statements 2 and 5 are true for the cross illustrated by the Punnett square.

The relationship that will increase a population's size is when the birth rate is greater than the death rate. Thus, the correct option is D.

The population size may be defined as the presence of a number of individual organisms within a population irrespective of their gender.

When the Death rate > birthrate, the population size decreases.

When the Emigration rate > immigration rate, the population size decreases.

In population size, the number of males and females does not bother the reflection within the population.

When the birth rate is higher than the death rate, the number of people in the population drastically increases with respect to time.

Therefore, the relationship that will increase a population's size is when the birth rate is greater than the death rate. Thus, the correct option is D.
