Answer:

An example some organisms unconsciously drive the selection of others is DOMESTICATION in plants

Explanation:

In plant domestication, unconscious selection brought about by the fact that the plants concerned were taken from their original wild habitats and placed in new and very different human-made or human-managed environments.

The shift in the ecology led automatically to drastic changes in selection pressures. Numerous adaptations vital for survival in the wild environments lost their fitness under the new sets of conditions. New traits were automatically selected, resulting in the build-up of characteristic “domestication syndromes,” each fitting the specific agricultural environment provided by the farmer.

With this explanation, it can be established that the wild plants unconsciously drive the selection of domestic plants, through a change in habitat by farmer

Explain how it is possible to have thousands of different protiens when there are only 20
solmaris [256]
This is possible because proteins are created from different combinations of amino-acids. While we only have 20 different kinds of aminoacids, these 20 kinds can create thousands of combinations that we can observe in our bodies and bodies of other mammals as well as other organisms.

Answer:

The exchange of biological material between tissues and blood vessels.

adoni [48]

Answer:

e. infection causes lymphocytes to divide more rapidly

Explanation:

The cell cycle includes interphase and M phase which in turn together produce daughter cells from the existing parent cells. DNA replication occurs during the S phase of interphase to ensure that the daughter cells obtain the identical DNA present in the parent cell.

Lymphocytes are one of the types of white blood cells and are involved in cell-mediated and antibody-mediated immune responses. These cells are present in the blood as well as in lymphatic tissues. During the given experiment, lymphocytes exhibited a higher rate of incorporation of labeled nucleotide after the introduction of a pathogen in the culture. This suggests that the introduction of pathogen triggered the cell division in lymphocytes to produce more lymphocytes to fight the infection.
