what is an enzyme that begins the digestion of proteins?
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids

Why is DNA an important molecule for our cells
Answer:
DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.
A science researcher has developed a computer model of the process of DNA replication in a eukaryotic cell. The model includes the following
sequence of bases in one strand of the DNA molecule.

The revisions to the model that would be most useful for the researcher to include is the replacement of thymine (T) with uracil (U) in the DNA molecule.
What do you mean by Transcription?Transcription may be defined as a process by which DNA is converted into mRNA in the nucleus of the cell.
In RNA, thymine is replaced by Uracil because during the elongation process, the presence of adenine in the DNA strand message the RNA polymerase to attach uracil in the complementary area of the elongated RNA strand.
Apart from this, Uracil requires less energy in the production as compared to thymine.
Therefore, the revisions to the model that would be most useful for the researcher to include is the replacement of thymine (T) with uracil (U) in the DNA molecule.

How are humans changing the carbon cycle?
Humans are planting more trees to add more oxygen to to the carbon cycle.
Humans are adding carbon to the Earth by over-farming,
Humans are burning carbon and putting it into the atmosphere.
Humans change the carbon cycle by burning carbon and putting it into the atmosphere. Thus, the correct option for this question is C.
What is the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. This cycle governs the exchange of carbon and its derivatives among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
The activity of Plants in the carbon cycle is determined by the fact that they breathe carbon dioxide. Humans are often cutting them down and the carbon dioxide stays in the air.
Apart from this, the burning and combustion of fossil fuels, trees, and chemicals increase the level of carbon in the atmosphere. Due to these human actions, the carbon cycle may be changing gradually.
Therefore, the correct option for this question is C.

A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.
Answer: c. The dark colored moths will experience disruptive selection.
Explanation:
The tree bark is light in color which means that while the light colored moths will be able to blend in, the dark colored moths will not. This will lead to the dark colored moths being hunted more by the bird leading to a sharp decrease in their numbers.
Disruptive selection occurs when an extreme trait is preferred over an intermediate one with little advantage in that environment. The dark moths will experience disruptive selection because the light moths are preferred for survival.

9. What will happen to the amount of oxygen if the amount of sun increases?
Answer:
8. Glucose (C6H12O6)
9. The plant will synthesize more, thus increase the amount of oxygen until a limiting factor prohibits the plant from synthesizing that much oxygen.
Explanation:
Glucose is the other product produced in this image besides oxygen.
What are the functions of glucose?Glucose is the main type of sugar in the blood and is the major source of energy for the body's cells. Glucose comes from the foods we eat or the body can make it from other substances. Glucose is carried to the cells through the bloodstream.
Glucose monosaccharides (not as part of starch) are also found naturally in some foods. The most concentrated whole food source of glucose monosaccharides is honey, followed by dried fruits such as dates, apricots, raisins, currants, cranberries, prunes and figs.
Glucose consists of three elements such as carbon, hydrogen and oxygen. 6 carbon atoms bonded together as a chain with additional atoms of oxygen and hydrogen.

why is vacuole in plant cell larger than a vacuole in an animal cell?
Answer:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. In animal cells, vacuoles are smaller but more in number because they do not require vacuole for rigidity or pressure.

In determining probabilities all you need to do is count and then divide by the number of results.
What is punnett square?A Punnett Square is a useful tool for forecasting the changes and probabilities that can result from cross-breeding. This includes foreseeing the mating of different species, including humans and animals.
It is asking the chances of having green seeds and that's the recessive allele. For recessive traits to be expressed, there can't be a dominant trait next to it because the dominant trait will always be expressed. So the expected result should be yy (two lowercase) if you want the recessive trait to be expressed.
In the Punnett square of the second generation, there is 1 out of 4 yy genotype. So then divide 1 by 4 and multiply it by 100% to get the probability in percent. So in short, the answer is 25%.
