A wet-mount slide of red onion cells is studied using a compound light microscope.
One of the cells has seen under high power is shown below in the picture (Sorry the picture is bad)
Part A: identify the name of each structure A, B, and C.
Use the terms listed as a word bank. Cell wall, Cytoplasm, and cell membrane.
Part B: A highly concentrated Salt solution has been added to the slide that this plant cell is on. Explain in detail what you would expect to see happening to the plant cell as a result.
Part A: A= cytoplasm, B= cell wall and C= cell membrane.
In Part B under this condition, we expected to see the phenomenon called plasmolysis.
How, explain your answer briefly?Eukaryotic cells consist on a cytoplasm (internal medium) which contains different organelles. Covering the cytoplasm we found a first thin layer called cell membrane and an external rigid layer called the cell wall.
When a cell is subjected to a media with a salt concentration higher than salt concentration inside the cell (hypertonic media), water inside the vacuole (an organelle that constitutes almost 90 % of cell volume and contains water) tends to move out of the cell in response to the concentration gradient.
This phenomenon is called plasmolysis and is possible because of the permeability characteristics of cell membrane and cell wall.
Thus, this could be the answer.

Contrast how the shape or polarity of two different cellular communication molecules are detected by their target cell differently: oligosaccharides on cell surfaces, neurotransmitters, steroid hormones, polar hormones.
Cell receptors located on the surface identify specific signals and thus trigger different signaling pathways.
What is a cell receptor?A cell receptor is any type of macromolecule in the cell surface that binds to a specific ligand and thus triggers a concomitant cell response.
Cell receptors such as surface oligosaccharides or hormone receptors may trigger the activation of transcription factors and genes associated with phosphorylation in a signaling pathway.
The shape and polarity of communication molecules are fundamental to achieving effective binding by means of cell surface receptors.
In conclusion, cell receptors on the cell surface trigger signaling pathways.

Describe how the shape and size of nucleotides are important in the structure of double-stranded DNA.
The shape and size of nucleotides are important in the structure of double-stranded DNA because it allows DNA replication and protein synthesis to occur.
What is DNA?This is referred to as deoxyribonucleic acid and contains the genetic instructions in organisms.
The double stranded shape and size allows for a copy of DNA to be made during reproductive processes. This is therefore the reason why DNA has such shape and size in this context.

Guinea pigs can produce different coat colors, white, brown, and mixed white/brown (agouti). The allele B is codominant with allele W (white coat). Cross an agouti colored Guinea pig with a brown Guinea pig. What are the odds of the offspring; 1/2 homozygous white, 1/2 heterozygous brown; 1/4 homozygous brown, 1/2 heterozygous agouti, 1/4 white; 1/2 heterozygous brown, 1/2 homozygous
In a cross of an agouti heterozygous (AB) colored Guinea pig with a brown (BB) Guinea pig the odds of the offspring is 1/2 WB and 1/2 BB (1/2 heterozygous agouti, 1/2 homozygous brown).
What is codominance?Codominance is a genetic phenomenon where both alleles are expressed in heterozygous individuals.
In this case, the allele B is codominant with allele W and produces heterozygous (WB) colored Guinea pigs such as one of the parents.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.
What is Active transport?Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.
During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.
But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

What two processes make up cell division
Answer:
Mitosis and Meiosis
How does cell division work?The cell that is dividing in a cell division process is referred to as the parent cell. Upon division, the parent cell produces two daughter cells. The next phase, known as the cell cycle, involves repeating the procedure.
Cells control their division by exchanging chemical signals via unique proteins called cyclins with one another. These signals function as switches that inform cells when to begin dividing and afterwards when to stop. For you to develop and for your wounds to heal, cells must divide. Cells must also cease dividing at the appropriate moment. Cancer can result from a cell's inability to stop dividing when it should, which is a condition known as cell division failure.
Now, how do cells divide?
There are two ways for cells to divide, depending on the type: mitosis and meiosis. Each of these strategies for cell division has unique qualities. A single cell splits into two identical cells with the same number of chromosomes during mitosis, which is one of the major distinctions between the two processes. Cell division of this kind is beneficial for fundamental development, repair, and maintenance. A cell divides into four cells during meiosis, each of which has half as many chromosomes. To promote genetic variety and sexual reproduction, the number of chromosomes must be cut in half.
Answer:
Mitosis and Meiosis
Explanation:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
If a cell has completed mitosis but not yet completed cytokinesis, what would it look like?
Answer:
If a cell has completed mitosis but not yet completed cytokinesis, the cell will be elongated and have two separate nuclei inside it.Cytokinesis is the stage of cytoplasmic division directly after nucleus division in Mitosis. when cytokinesis not occur there are two nuclei already been formed The cytoplasms of two daughter cells have not been separated

Which of the following is the primary source of energy for the brain?
Answer:
Glucose
Explanation:
Because of the following factors, glucose serves as the brain's primary energy source. Glucose may be easily catabolized to provide energy to the brain since it cannot tolerate interruptions in energy flow. Since the brain cannot store calories, a quick supply of chemicals that can provide energy is essential for the brain's smooth operation. In this situation, blood can easily transfer glucose. Although fatty acids provide a source of energy for the rest of the body, they are unable to cross the blood-brain barrier because they are bound to blood albumin in blood plasma. These justifications explain why glucose serves as the brain's main source of energy. Ketone bodies could be the secondary source.
