Answer:
C. Beak size is an inherited trait in the finch population under study.
D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.
E. Beak size varies among the birds in the finch population under study.
Explanation:
The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.
If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.
Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.
Answer:
C) Dendritic cells.
Explanation:
Dendritic cells are types of immune cells that carry out immune responses by presenting antigens on its surface to other immune system cells.
They are derived from the bone marrow and have tree-like structures. Dendritic cells are found in the skin, lungs, nose stomach and intestines. They are phagocytes and are antigen presenting cells (APCs).
Dendritic cells work by capturing the antigens from foreign bodies and processing and presenting these antigens on their cell surfaces for recognition and action by other cells of the immune system.

Answer:
elastic arteries, muscular artery, arterioles, capillary, venules, medium veins, large veins,
Explanation:
There are three types of blood vessels a) arteries b) capillaries and c) Veins. Arteries are responsible for carrying blood from heart to all other parts of the body. The arteries arising from heart are large in size which then keep on branching and becoming small enough for cellular exchange.
Capillaries are intermediary to veins and the arteries as they allow exchange of nutrient and release of waste product to and from from cells.
Lastly, veins carry deoxygenated blood from organs to the heart. Vieins become larger in size as they get close to heart.
Hence, the correct order is
elastic arteries, muscular artery, arterioles, capillary, venules, medium veins, large veins,
