Answer:
Depends on temperature
Explanation:
If the volume of a container is increased, so does the temperature.
If the volume of a container is decreased, so does the temperature.
Answer:
All antigen receptors produced by a single B or T cell are identical and bind to the same epitope.
Explanation:
Epitope or antigen determinant is the specific part of the antigen that is recognized by an antibody or T-cell receptor. During clonal selection, a lymphocyte proliferates and differentiates to form a group of highly specialized cells in response to a specific antigen present in the body.
The result of clonal selection is the formation of a population of identical cells that recognize the same specific epitope of the same antigen. A lymphocyte that undergoes clonal selection gives rise to two major types of cells in the clone: effector cells and memory cells.
For instance, the clonal propagation of B lymphocytes forms plasma cells (the effector cell) and memory cells. The plasma cells synthesize and secrete specific proteins called antibodies. All the antibodies derived from a plasma cell can bind to and inactivate the same specific antigen.
Answer:
Rudolf Virchow first explained that cells comes from pre existing cells
Answer:
The correct answers are: B, C and D.
Explanation:
(B) Darwin, which focused on the appearance of new species as substitutes for extinct species of the same natural group, making the comparison of fossil and modern specimens of the same natural group.
(C) Birds that are known as "Darwin's finches", For example, there were three or four distinct "varieties" or species of finches on the different islands. The most important differences between the species are in the size and shape of the beak.
He saw the slightly different forms of finches and turtles on different islands as early stages in the development of new species from common ancestors.
(D) He did observe that on the islands there are different forms of animals that would otherwise be similar. Their attention was also directed to the differences in the shapes of the giant tortoise shells, with each island in a slightly different form.
The replacement of extinct species by modern ones, as in the case of giant armadillos and sloths, the micro-version of the same geographic replacement patterns in different islands in a chain, finches and turtles.
It is D)
Living organisms such as bacteria are likely...
