Answer: Hydrolysis
Explanation: It is hydrolysis. In hydrolysis, larger molecules, such as polymers, are broken down into their monomers by the action of an enzyme and the addition of a water molecule.
A hydrolysis reaction involves the breakdown of large molecules by enzymes and the addition of water.
Explanation:The breakdown of large molecules by enzymes and the addition of water is known as a hydrolysis reaction. The term hydrolysis is derived from 'hydro-' which means water and '-lysis' which means to break down. In the process of hydrolysis, a water molecule is added to the substance, which causes the substance to separate into two parts. This is an important process in many biological systems, such as the digestion of food in the body.
Enzymes act as catalysts, facilitating this reaction by lowering the activation energy required for the hydrolysis to occur. Hydrolysis is essential for various biological processes, such as digestion, where complex carbohydrates, proteins, and fats are broken down into their constituent monomers like glucose, amino acids, and fatty acids. These monomers can then be absorbed and utilized by the body for energy production and various cellular functions.

There are 5 nitrogenous bases in DNA and RNA. How do the base pairs match up in DNA and RNA?
Answer:
In DNA there are 4 bases (adenine,guanine,thymine and cytosine)
adenine match with thymine while guanine match with cytosine.
RNA also contains 4 bases(adenine,guanine,uracil and cytosine)
adenine match with uracil while guanine match with cytosine.
In DNA, adenine pairs with thymine and guanine pairs with cytosine. In RNA, adenine pairs with uracil and guanine pairs with cytosine.
Explanation:The nitrogen bases in DNA and RNA are called 'nitrogenous bases' because they contain nitrogen atoms in their structure. In DNA, the four nitrogenous bases are adenine (A), guanine (G), cytosine (C), and thymine (T). In RNA, the bases are adenine (A), guanine (G), cytosine (C), and uracil (U).
Purines and pyrimidines are two types of nitrogenous bases. Purines, such as adenine and guanine, have a double-ring structure, while pyrimidines, such as cytosine, thymine, and uracil, have a single-ring structure.
Each base pairs with a complementary base. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). In RNA, adenine (A) pairs with uracil (U), and guanine (G) pairs with cytosine (C).
Which of these statements best explains why the inner core of Earth does not melt although it has very high temperatures?
The liquid outer core cools the inner core.
The plastic mantle conducts the heat away from the core.
The iron which makes up the core melts at very high temperature.
The different layers of Earth exert pressure to keep the inner core solid.
Please don answer unless your fairly sure of yourself. thank you
Answer:
The core is in a cube structure, extreme temperatures make the atoms to move so quickly that there is no alteration of the structure hence, no melting.
Explanation:
In the case of extremely high temperatures, atoms change position but still keep their original shape.
Further explanation:
In the case of high temperatures, the atoms making up a cube move rapidly and change position, the change of position is the melting.
Answer:
Option D, The different layers of Earth exert pressure to keep the inner core solid.
Explanation:
Due to extreme high pressure at the core of the earth, the iron does not convert into liquid form. According to a research conducted by KTH Royal Institute of Technology, the iron acquires the body-centred cubic structure when it is at normal pressure but when the pressure is extremely high the iron acquires the shape of hexagonal with 12 points which is a close packed structure. Due to this close pack structure, iron remains solid in the inner core of earth.
Hence, option D is correct

answer for us test prep
1). Karen is looking at a slide of an onion root tip under a microscope. She noticed that not all the cells look the same. Which of these best describes why all the cells are not identical?
A). The root is continuing to grow so the cells are going through mitosis
B). Some of the cells are cells and others are cells in the stem
C). There is a problem with the slide and it must be contaminated
D). The cells are turning into the actual
2). What is the difference between cells B and E?
A). B contains fever chromosomes than E
B). B is in anaphase and E is in metaphase
C). B is an animal cell and E is a plant cell
D). B it's two separate cells and E is a single cell
Answer: 1.C
The first question is pretty self explanatory because the cells won’t look the same because more cells are still developing and going through mitosis.
2.B
The second one is B because in metaphase the spindles align in the middle and E shows that. Image B is anaphase because the spindles moves to opposite ends.
The cells in the onion root tip are not all identical because the root is continuing to grow and the cells undergo mitosis. Cell B contains fewer chromosomes than cell E.
Explanation:The reason why not all the cells in the onion root tip look the same is because the root is continuing to grow and the cells are going through mitosis (Option A). In mitosis, the cells divide and produce new cells, resulting in a variety of different cells with different structures and functions.
Regarding the difference between cells B and E, cell B contains fewer chromosomes than cell E (Option A). During anaphase of mitosis, the paired chromosomes separate and move to opposite ends of the cell, while in metaphase, the chromosomes align in the middle of the cell.

A population of hyenas inhabits a tropical savanna. At the beginning of the year, there were 100 hyenas in the population. Throughout the year, 20 hyenas died, 35 hyenas were born, 5 hyenas migrated into the population, and no hyenas left the population. What was the size of the population at the end of the year?
At the end of the year, there were (blank) hyenas in the population.
Answer:
120 is the size of the population at the end of the year
Explanation:
Size of the population is given by
Total number of Hyenas present in the population + Total number of Hyenas born + Total number of Hyenas migration into the population – Total number of Hyenas died
Substituting the given values in above equation, we get -
[tex]= 100 + 35 + 5 -20\\= 120\\[/tex]
120 is the size of the population at the end of the year
At the end of the year, there were 120 hyenas in the population.
Step 1: Calculate the change in population due to births, deaths, and migration:
Starting population: 100 hyenas
Deaths: 20 hyenas
Births: 35 hyenas
Migration in: 5 hyenas
Migration out: 0 hyenas
Step 2: Calculate the net change in population:
Net change = Births - Deaths + Migration in - Migration out
Net change = 35 - 20 + 5 - 0 = 20 hyenas
Step 3: Determine the population size at the end of the year:
Population at the end of the year = Starting population + Net change
Population at the end of the year = 100 + 20 = 120 hyenas
Step 4: Conclusion:
At the end of the year, there were 120 hyenas in the population.

Samuel wanted to test how well three types of soil holds water. He poked several small holes in the bottoms of three plastic cups and filled one with sand, one with clay, and one with loam. He set each cup of soil inside a slightly smaller cup, like in the picture shown. He poured the same amount of water into each cup of soil and came back one hour later to measure how much water had dripped through each soil. The following amounts of water were found at the bottoms of the smaller cups.
Sand: 4 ml
Clay: 0 ml
Loam: 2.5 ml
Based on this information, which statement is true?
A) He poured the most water into the cup containing sand.
B) He did not pour any water into the cup containing clay.
C) Clay retained the most water out of the three substances.
D) Sand retained the most water out of the three substances.
the answer to your question is D)
Answer:
C) Clay retained the most water out of the three substances
Explanation:
Based on this information, "clay retained the most water out of the three substances" is the statement that is true.
The experiment was carried out to test the water holding capacity of the three types of soil. In this experiment, 0ml of water was found at the bottom of the smaller cup which contains the clay soil, while sand and loam soil has 4mls and 2.5mls respectively. Clay soil has 0ml of water at the bottom of the cup because it retained the most amount of water and has the highest water holding capacity than the other soils. Clay soil has smaller fine particles. The smaller a soil particles are, the larger the soil’s surface area is, and so the more water the soil retains. This is why clay soil retained the most amount of water in the experiment.
which determines carrying capacity?
it is determined by limiting factors for example if I had a small apartment I couldn't fit 50 people in there so the carrying capacity would be lower that that because of the limiting space.
Answer:
Limiting factors.
Explanation:
Carrying capacity may be defined the maximum number of individuals that can be supported by the environment without causing any problem to the environment. The population size increases below the carrying capacity and population size starts decreasing above the carrying capacity.
Limiting factors like food, surface area, water can limit the population growth. The absence of food may result in decline in the population. Hence, limiting factors determine the carrying capacity.
Thus, the answer is option (4).
How does energy usually flow in ecosystems?
A. from the Sun through consumers to producers
B. from the Sun through producers to consumers
C. from producers through the Sun to consumers
D. from consumers through the Sun to producers
Answer:
B. From the Sun through producers to consumers.
Explanation:
All energy is obtained from the Sun. So the producers (in this case plants, fruits, vegetables) receive that energy through the process of Photosynthesis. After that transfer, consumers (primary, secondary, and tertiary) gain 10% of that Sun obtained energy from its producers.

Where is light penetration in a river or stream likely to be lowest
The light penetration in a river or stream is likely to be lowest AT THE MOUTH.
Streams and rivers are bodies of water that flow in one direction only; they travel from the source to the mouth. A river mouth refers to the part of a river, where the river merge with another river, stream or other forms of water bodies.
Around the mouth of the river, the water is usually murky as a result of all the sediments that the river has picked up during its travel upstream, this significantly reduce the amount of light that can penetrate the water at this point.
Due to decrease in the amount of light that penetrate the water at the mouth region, there is decrease in the level of oxygen in the water and a corresponding decrease in diversity of plant and animals that can be found in the mouth region of the river.

Which statement is the best example of the law of conservation of energy?
A train traveling down a hill loses potential energy that is then stored in the ground.
An animal's energy is permanently stored in chemical bonds when it eats food.
Chemical energy in a car engine is destroyed as it burns and releases exhaust into the air.
Radiant energy from the Sun is not lost but transformed into other forms of energy.
The law of conservation of energy is where energy is distributed or transported to other objects or things, and energy is never destroyed or created. It would be C because it talks about while driving the thermal energy of the engine is being used and goes into the air. The others dont explain the transfer of energy as well. I hope this helps.
Answer: Option (d) is the correct answer.
Explanation:
According to law of conservation of energy, it is stated that energy can neither be created nor it can be destroyed but it can be converted into one form to another.
For example, radiant energy from the Sun is not lost but transformed into other forms of energy.
Energy can never remain stored forever in any substance or living thing.
Thus, we can conclude that the statement radiant energy from the Sun is not lost but transformed into other forms of energy, is the best example of the law of conservation of energy.

What are the examples of life cycle adaptations
Biological adaptations are the evolved traits that increase an organism's chances of survival and reproduction. Examples include the timing of plant growth cycles to maximize light capture in both terrestrial and aquatic environments, and the different life cycle patterns such as haplontic in algae, diplontic in humans, and alternation of generations in ferns.
Explanation:Adaptation is a key concept in biology, referring to how living organisms evolve traits that enhance their survival and reproductive success in a given environment. These adaptations can be incredibly diverse, reflecting the variety of challenges faced by organisms across different habitats. Let's look at some examples of life cycle adaptations in both terrestrial and aquatic environments.
In terrestrial ecosystems, plant life cycles often depend on the availability of light. Some plants have adapted to flower or grow at different times to maximize their light capture, which is essential for photosynthesis and subsequent survival and reproduction. An example of this is the desert wildflower, which blooms immediately after rare rainfall to take advantage of the fleeting availability of water and light.
In aquatic ecosystems, light availability can be limited by water absorption, depth, and the presence of other organisms. Algae and seagrasses, for instance, have life cycles that accommodate these conditions, growing in patterns and at depths where light is sufficient for their needs.
Three main types of life cycles in multicellular organisms include haplontic, diplontic, and alternation of generations (haplodiplontic). The haplontic life cycle, exemplified by many algae, is where the organism spends most of its life cycle in the haploid stage. In the diplontic life cycle, seen in animals like humans, the diploid stage is dominant. Lastly, the alternation of generations is characteristic of plants like ferns, where both haploid and diploid stages are distinct and multicellular.
in figure 32-3 a muscle that moves food through your digestive system is shown in
B
Explanation;B are smooth muscles.Smooth muscle is found in the walls of hollow organs throughout the body. Smooth muscle contractions are involuntary movements triggered by impulses that travel through the autonomic nervous system to the smooth muscle tissue.The smooth muscle of the alimentary canal or the digestive tract facilitates the peristaltic waves that move swallowed food and nutrients.Answer:
Option B.
Explanation:
Smooth muscles are spindle shaped, non-striated muscles and have uninucleated fibers. They are involuntary muscles and are found in the walls of internal organs such as the organs of digestive system. Peristalsis of smooth muscles of digestive system creates a wave like pattern of muscle contraction and moves the food through the system. Images A and B represent skeletal and cardiac muscles respectively both of which have striated fibers.
One difference between organisms being classified as kingdom plantae or kingdom animalia is the way organism gets food
The kingdom Metaphyta (vegetable) is able to obtain food through photosynthesis (it is autotrophic). Metazoa kingdom (animal) is heterotrophic, that is, it only obtains food by looking in the environment (it does not produce its own food).
of All of the organisms living today, what percentage will eventually become fossils
A very small percentage of all living organisms will become fossils, as the process requires specific and rare conditions. Fossil evidence shows that existing species at any time represent only about 0.2-2% of species that have existed. Extinction also contributes to the rarity of potential fossils.
Explanation:Considering all of the organisms living today, only a very small percentage will eventually become fossils. The process of fossilization is rare and occurs under specific conditions; remains must be covered quickly by sediments or preserved through other extraordinary means, such as being trapped in tree resin or frozen in glaciers. Given that fossils are critical for understanding the Earth's history and the evolution of life, their scarcity highlights their value for scientific research.
Based on scientific analysis, the average lifespan of a species based on fossil evidence is about 1-10 million years, suggesting that at any given time, existing species represent only a fraction—about 0.2-2%—of all the species that have ever lived. Furthermore, extinction is an ongoing process, affecting a significant portion of living species, which also influences the potential for organisms to become fossilized.
What direction do the Sun, Moon, and stars appear to move in the sky?
The Sun, Moon and stars all appear to rise in the East and set in the West, because the Earth revolves on its axis in the opposite direction from West to East every 24 hours.
The illusion of the Sun, Moon, and stars rising in the East and setting in the West is attributed to Earth's rotation. Their individual motions and our planet's tilt and orbit result in diverse paths and speeds. The idea of fixed and wandering celestial bodies arises from these observations.
Explanation:The Sun, Moon, and stars, despite their inherent individual motions, seemingly move in the same path across the sky due to the Earth's rotation. This creates the illusion of these celestial bodies rising in the east and setting in the west. This phenomenon, observed over centuries, led the ancient Greeks to the idea of celestial bodies as 'fixed stars' and 'wandering stars' or planets, with the latter having independent motions superimposed on the daily rotation of the celestial sphere.
The Sun's apparent motion is affected by the tilt of Earth's axis and our planet's orbit around the Sun, causing its path to change and moving north and south throughout the year. The Moon, Earth's closest celestial neighbour, moves approximately 12 degrees per day and completes its circuit around the sky approximately once a month.
Planets are also wanderers in the sky. Their apparent motion is more complex due to their own orbit around the Sun. This results in them moving against the background of the fixed stars, reflecting an underlying order of the heliocentric, or Sun-centered, model of our solar system.
