Answer:
The essential factor to increase the number of cells in a growing organism is that each and every cell has a complete copy of DNA.
Explanation:
The development and growth of an organism is based on the multiplication of its tissue cells. Cell multiplication in somatic cells occurs through mitosis, a process that allows obtaining two identical daughter cells from a progenitor cell.
DNA contains all the genetic information belonging to a living organism. In the process of mitosis, the DNA of each cell must be replicated so that each daughter cell has a complete copy of the original DNA. This ensures that each cell resulting from mitosis has the same structure and function as the original cell.
The other options are not correct because:
The size of the cell is important, since each cell has defined characteristics, according to the tissue it must form. Each and every cell needs to have a complete DNA. In somatic cells, DNA does not vary from one cell to another.Related Questions

Describe the two processes necessary for sediments to lithify into sedimentary rock.

1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.

Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.

What part(s) of photosynthesis would the plant not be able to perform if there were no rain?
Answers
Answer:
When plants are not watered properly they wilt. ... When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn't get enough water, the pressure inside the stems and leaves drops and they wilt. Plants also need water for photosynthesis.
Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
When a plant does not receive enough water, the water pressure inside the stems and leaves decreases and the plant wilts. Water is also required by plants for photosynthesis.
Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Therefore, Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.

Answers
Answer:
B is the answer
Explanation:
The cell membrane is the boundary of the cell, separating the cell material from the outside environment, hence option B is correct.
What is the function of the cell membrane?All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.

Shoot the Golgi Apparatus. Fill in the blanks: Golgi receives ANSWER containing ANSWER that were sent by the ANSWER Then it modifies ANSWER and send them where they need to go.
Answers
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi complex, where it occurs the final association of carbohydrates with proteins. The Golgi complex sends proteins to their different destinies. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.

When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answers
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.
What is endosperm?The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.
Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.
The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.
