Explanation:

Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.

The pancreas is an organ present in some animals. It produces enzymes that are used in the digestive system of the animal. Which cell structure is likely to be abundant inside pancreas cells?

A. Cell walls, because cell walls cannot be digested by enzymes
B. Chloroplasts, because chloroplasts provide the energy for making enzymes
C. Nuclei, because nuclei contain the instructions for synthesizing enzymes
D. Ribosomes, because enzymes are synthesized on ribosomes

Answers

Answer: the answer is D Ribosomes, because enzymes are synthesize on ribosomes

Explanation:

Because we need more protein to be produced in are pancreas

The messenger RNA (mRNA) sequence is read by the ribosome, which then interprets the genetic code into a predetermined string of amino acids. These amino acids then form lengthy chains, which fold to form proteins. Thus, option D is correct.

What is the role of ribosomes in the enzyme formation?

Protein synthesis is always carried out by the ribosome, which converts the genetic code produced in mRNA into an amino acid sequence.

Ribosomes carry out the initiation, elongation, and termination of peptide synthesis using metabolic energy, soluble transfer RNA's, and cellular auxiliary proteins.

The biocatalyst, which are proteinaceous in nature, are enzymes. The ribosomes found on the endoplasmic reticulum produce these. A cell's ribosomes are referred to be its “protein factory.”

Therefore, Ribosomes, because enzymes are synthesized on ribosomes.

Explanation:

The temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

What is Thunderstorm?

A thunderstorm is defined as a storm with lightning and thunder produced by a cumulonimbus cloud, usually producing strong winds, heavy rain, and sometimes hail. Thunderstorms are so called because of the thunderous loud noise they make.

There are three basic elements that lead to the development of thunderstorms: moisture, an unstable atmosphere, and some way for the atmosphere to move where the moisture is necessary to produce thunderstorm clouds and precipitation.

Thus, the temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

Vernon is using the diagram shown below to develop a model of photosynthesis. The letters A, B, and C each represent a reactant or product of the process.

In the light-dependent reactions, light strikes the oval thylakoids. Compound A enters the thylakoid, and compound B leaves it. In the light-independent reactions, compound C enters a cycle in the stroma, and sugars leave the cycle. ATP and NADPH cycle between the two sets of reactions.

Should water (H2O) be included in the model as a reactant or product? If so, how should it be included?

A. Yes, as reactant A.
B. Yes, as product B.
C. Yes, as reactant C.
D. No, it should not be included.

Answers

Yes a reactant I don’t understand the a and c part it’s one of those two

Photosynthesis is the process of preparing food in the presence of light, water, and carbon dioxide. Photosynthesis can be light-dependent or light-independent reactions.

The correct answer is:

Option A.  Yes, as reactant A.

The mechanism can be explained as:

1. Light-dependent reactions convert light energy into chemical energy.

2. The light-dependent reactions require water and light to yield oxygen, hydrogen, and energy molecules.

3. The light is used to break down the molecule of water into oxygen and hydrogen when the light strikes the thylakoid.

4. The ATP is generated in the stroma of the thylakoid membrane. The excited electrons released during the splitting of water is utilized to produce high-energy molecule.

Thus, water molecule should be used as a reactant because it yields products.

Which of the following describes what might happen with a sudden increase in precipitation in the grassland biome? (4 points)

a
Rise in drought-tolerant plants

b
Salt and sediment deposition

c
Increase in plant and animal diversity

d
Nutrient loss and soil erosion

Answers

The answer would be a

Increase in plant and animal diversity describes what might happen with a sudden increase in precipitation in the grassland biome. Therefore, the correct option is C.

What is precipitation?

Precipitation is the phenomenon in which condensed water vapors falls on the earth's surface under the influence of gravity.

A sudden increase in precipitation in the grassland biome can provide more water for plants and support their growth, which can lead to an increase in plant productivity and diversity. This in turn can provide more food and habitat for animals, leading to an increase in animal diversity as well.

While there may be some nutrient loss and soil erosion as a result of increased runoff, the overall effect on the ecosystem is typically positive in terms of increased biodiversity. Salt and sediment deposition are not typically associated with an increase in precipitation in the grassland biome. Therefore, the correct option is C.

National Zoo biologist Rob Shumaker holds up some folded bags containing chopped fruit. "Okay, Azywant to tell me what this is?" In front of the rusty-haired ape is a computer screen showing some symbols. Each one stands for a word. Azy lifts his long, graceful hand and points to the symbol for cup. A buzzer sounds. The screen shows an hourglass symbol that means his answer is wrong.For the first time this afternoon, Azy seems confused. Shumaker shows him the bags again, and again the orang points to "cup". On the fourth try, Azy figures it out. He points to the symbol for "bag," and Shumaker hands him the paper bags through an opening in the Plexiglas between them. Azy picks out the fruit and reluctantly hands back the bags when the biologist asks politely, "Azy, can I have those?"For the last three years, Shumaker has been working with Azy and five other orangutans and the Zoo's Think Tank building. In addition to these great apes, Think Tank Researchers are studying creatures as various as hermit crabs, leaf-cutter ants, and macaques. They hope to learn whetherand howanimals think. Some of the scientists look at tool use. Others observe the animals' social life. Shumaker would like to know if orangutans can learn language.Which answer best summarizes this text?(A) Azy is a male orangutan who is taking a vocabulary test at the National Zoo. Shumaker has been studying Azy and five other orangutans for three years to see whether the great apes can learn language. Other researchers at the Zoo's Think Tank building are studying other animals to learn more about how they think.(B) Azy is a 21-year-old male orangutan. He is taking a vocabulary test, but he gets the words "bag" and "cup" mixed up. A buzzer goes off because he is wrong. Azy has been studied like this for three years. Shumaker studies him at the Think Tank building at the zoo. Researchers are also looking at other animals to see if they can use tools and learn language and things like that. Azy is part of this study along with other orangutans and hermit crabs, leaf-cutter ants, and macaques.(C) Azy is a great ape called an orangutan. He has rusty-colored hair. He is taking a vocabulary test. A researcher holds up some bags, but Azy says they are cups. He is wrong. Scientists at the Think Tank building are studying animals. Azy is one of the animals being studied. The researcher wants to know if orangutans can learn language. He is studying Azy and five other orangutans.(D) Azy was getting 100 percent on his vocabulary test. But then the orangutan got an answer wrong.
