the diagram represents protein synthesis which is essential to the function of all cells. what is represented by C?
The part of the diagram that represents transcription is C.
What is the essential part of every cell?Transcription simply means the process where the information that's in a strand of DNA is copied into a new molecule of messenger.It should be noted that transcription takes place in a nucleus. The diagram depicted represents structures and processes involved in protein synthesis in an animal cell. The part of the diagram that represents transcription is X.As the name implies, protein synthesis, involves the synthesis of proteins in a cell. Cellular structures in a cell called organelles are responsible for this function. These organelles include ribosome and rough endoplasmic reticulum.The ribosome is an organelle found in all cell types and is the site for the synthesis of proteins in the cell. The ribosome is where translation (process of synthesizing amino acid chains from mRNA) occurs. The chains of amino acid later becomes the protein.The Rough endoplasmic reticulum (RER) gets it "roughness" from the fact that RIBOSOMES are attached to its surface. Due to this, the RER functions in the synthesis of proteins. The RER is involved in the production, folding and packaging of proteins in eukaryotic cells. The RER processes the polypeptide produced by the ribosome into proteins that are carried to varying destinations.To learn more about cells refer to:

Diploid organisms are those that can reproduce sexually. Only the sperm and egg contain haploid cells in humans.
What is reproduction?The process of creating new organisms (offspring) of the same kind is referred to as reproduction. By creating variations through DNA recombination, it aids in evolution. It contributes to the biological variety of the ecosystem.
Diploid cells have two complete sets (2n) of chromosomes. A diploid cell has two entire sets of chromosomes, whereas a haploid cell has one complete pair and half as many (n) chromosomes.
Thus, diploid organisms are those that can reproduce sexually. Only the sperm and egg contain haploid cells in humans.

A student is testing isopods’ response to light. Isopods (also known as pill bugs or sow bugs) are crustaceans that breathe through organs that need to be kept moist. The results of the experiment show that the isopods move away from light and gather in dark areas as soon as they hatch. Select two statements that explain whether this behavior by the isopods is innate or learned and what adaptive advantage this behavior may have.
A. This behavior appears to be innate, because the isopods could not have learned the behavior during the experiment. The animals exhibited this behavior as soon as they were exposed to the light, right after they hatched.
B. This behavior has an adaptive advantage for isopods because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring.
C. This behavior appears to be learned, because the isopods only exhibited this behavior after they were exposed to the light in the experiment.
D. This behavior is artificial and therefore does not have an adaptive advantage for isopods in nature, because those isopods that moved to dark, moist areas would more likely become food for predators and would not survive.
The behavior of isopods has an adaptive advantage for them because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring. Thus, the correct option is B.
What is Adaptive advantage?An adaptive advantage is a reproductive advantage in an organism that derives from being well-suited to the specific environment in which it lives. Adaptive advantage is likely to result in an organism that is producing more offspring than those organisms without the adaptive advantage.
Isopods show adaptive advantage because isopods move to dark areas away from light which are usually moist. The isopods that moved to the dark, moist areas were more likely to survive and pass the genetic trait to their offspring than other isopods.

How would the bonding of a purine with a purine alter the dna molecule
A purine interacting with another purine would be problematic for the structure of the DNA molecule.
One of the two categories of nitrogenous bases found in DNA is purines; the other are pyrimidines.
Adenine (A) and guanine (G) are examples of purines, and they invariably couple with thymine (T) and cytosine (C), which are complementary pyrimidine bases.
DNA molecule. In the DNA molecule, pairings of two purines, such as adenine and guanine or guanine and guanine, would result in a bulky structure that would not fit into the double helix properly. The hydrogen bonds between the two strands of DNA would be broken as a result, which might result in a break in the DNA strand and mutations.Purine-purine bonding is therefore not conceivable in a DNA molecule because DNA's structure is highly particular and meticulously controlled to ensure its stability and function. For DNA replication and transcription to work appropriately, which is crucial for the transmission of genetic information and maintenance of life, the right matching of purines with pyrimidines is required.learn more about purine here

The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.
What are the differences between animal and plant cells?Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.

One of the keys to success for Mendel was using pea plants. Explain how using pea plants allowed Mendel to control mating?
Mendel used pea plants in his experiments in which he was able to control mating because of the pollination characteristics of the pea plant.
What is Mendel's genetics?Mendelian inheritance of Mendel's genetics refers to certain patterns of how the traits or characteristics are passed on from the parents to their offspring.
Mendel used garden pea plant (Pisum sativum) in his experiment of how the characters or traits transfer from one generation to the next generation. Mendel had various reasons to use pea plants for his genetic experiment study such as the observability of the pea plant's traits, ease of reproduction etc. However, the main reason for him using garden pea plant is because these plants allowed him to have controlled mating that is what made the traits more controllable and therefore Mendel was sure about his observations and results.
It was possible because the pea plants, during their flowering periods, are protected from the alien pollinators, therefore he could control the pollination process in the pea plant, which was a crucial part in terms of accuracy and reliability of the results.
