maria [59]

Answer:

exponential growth

Explanation:

The organisms that are not native of a particular environment but are exposed to live in that particular environment are invasive species. Usually invasive species do not prove useful to the new area and prove harmful to the environment as well. There are some species of organisms that have been accidently introduced to new environment and have been accidently proven to be beneficial.

Explain the importance of immunological memory cells. Describe in detail how and when memory cells arise and explain how they fo
Vlad1618 [11]

Explanation:

<em>Immunological memory</em> is the property of the immune system to store information about a stimulus so it can mount an effective response if it encounters the same stimulus again being this second response quicker and stronger even after years since the first encounter.

This kind of response is dependent on many subpopulations within T and B lymphocytes and NK cells. When encountering an antigen, B cells recognize it by membrane antibody specifically binding to the antigen and then being activated to expand rapidly with their progeny clones differentiating into plasma and memory B cells, these last ones have a long life span to remain in the body, ready when another encounter with the same stimulus occurs, this is how the basis for effective immunizations happens.

I hope you find this information useful! Good luck!

Relate the analogy of “tug of war” to a water molecule.
ipn [44]

Answer:

water molecules undergo the 'tug of war' via the cohesion-adhesion theory

Explanation:

In plants specifically, a transpiration stream is formed via osmosis from roots into xylem and travels by the apoplast pathway to the leaves, where the water then evaporates from stomata into the surrounding air along the diffusion gradient. the water loss from the mesophyll cells lowers their water potential therefore water moves in via osmosis by both apoplast and symplast pathway from adjacent cells. water bonded to water= cohesion, water bonded to carbohydrates of xylem walls= adhesion. water is drawn up in tug of war-esc fashion against gravity to replace water evaporated, resulting in cohesion-adhesion theory.
