If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.
The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.
If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:
P: AA x aa
F1: Aa Aa Aa Aa all of the offspring are constricted
Another combination:
P: Aa x aa
F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.
So, the correct answers are:
• all of the offspring will have constricted pods
• 50% of the offspring will have constricted pods and 50% will have smooth pods.
Answer:
Option (a), (b), (c) and (d).
Explanation:
Cytokinesis may be defined as the process by which the cytoplasm of the cell is divided into the two daughter cell. This process is quite similar to the process of binary fission of prokaryotes.
The cytokinesis follows after the telophase stage. The cytoplasm with the organelles are divided into the daughter cells from the parent cell. This process is proceeded with the formation of the cleavge furrow in the animals ans divides into daughter cells.
Thus, the correct answer is option (a), (b), (c) and (d).
Cytotoxic t-cells are able to recognize infected body cells because <u>the</u> <u>infected cells display foreign antigens</u>.
<h3>What do cytotoxic killer T cells do?</h3>
The helper T cell and the cytotoxic T cell are the two main subtypes of T cells. Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumors. The TCR cannot directly bind antigen, unlike an antibody.
Killer T cells are also known as "cytotoxic" or "cytolytic" cells because they have unique molecular weapons that allow them to attack and kill other cells that are showing targets they are familiar with, such as a virus-infected cell or even a malignant cell. The processed cancer cell antigen, which is solely presented by MHC-class I, must be recognized by cytotoxic T lymphocytes. Helper T cells binding to a processed antigen on the same dendritic cell as the MHC-class II presenting a processed cancer cell antigen enhances cytotoxic T-cell complete activation.

<span>E)detritus-insect-frog-snake would best represent the food chain.
Detritus is a residual from plants that are decomposed. This will be eaten by insects such as flies.
After that, the flies will be eaten by the frogs who hunted on ponds before they eventually eaten by the highest level carnivore (such as snakes or Big birds)</span>
The thyroid gland regulates growth and development through the rate of metabolism.
