Pathologic anatomy examines all anatomic changes resulting from disease
Disease is the condition of the body when normal conditions are absent that is hindering the normal functioning of the body.
Anatomy is the field of biological sciences that are concerned with internal structures of the living organisms. It is divided into many branches- microscopic anatomy, human anatomy, embryology, comparative anatomy, phytotomy, zootomy, etc.
Pathologic anatomy is a branch of anatomy that deals with the examination of the diseases based on macroscopic as well as microscopic examination of the cells and the tissues.

Answer:
when placed in hyper tonic solution , the cytoplasmic volume of elodea plant will be reduced, this is because, elodea is a water plant with high water potential; therefore,with cytoplasm of high water potential elodea will loose water from the cytoplasm to the external; hypertonic solution, of lower of potential by osmosis. This reduces the cytoplasmic volume.With time the protoplasm pulls away from the cell wall, and the whole elodea structure shrinks.
However,, when RBC is placed in hypotonic solution, of higher water potential than the RBC (which has lower water potential), the cytoplasmic volume increases as water moves into the cytoplasm by osmosis. The RBC swells and eventually busted. This is hemolysis.

Answer:
Coevolution
Explanation:
Coevolution is a process in which two species evolve together because they exert selective pressures mutually. This means that one of the species changes genetically in response to a genetic change in another species. Thus, both species reciprocally affect each other's evolution. These genetic changes, which go hand in hand, are reflected in the phenotypes, that is, in the morphological traits of the species.
The coevolution of plants (i.e the orchid) and pollinators (i.e the moth) is a typical example of coevolution. The flowering plant adapt to a pollinator, which in turn adapts to the plant. In this case, the nectar tube and the tongue of the moth coevolved together and the two species benefit from that. The orchid guarantees the dispersion of its pollen while the moth guarantees its food.
Fever is the rise in body internal tempreature. <span>The tempreature rises in response to threats such as bacterial or viral infections.
So when fever occurs , it proves that bacterial or viral infections has been killed by the immune system or treated.</span>
