Explanation:

A feedback loop involves:

a receptor
control center
an effector

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. For instance, the regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

What are the reasons for the several day delay in a primary response. Infection______. A. transport to secondary lymphoid tissue

Liula [17]

Answer:

The correct answer is D. proliferation and differentiation.

Explanation:

Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.

Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.

So the correct answer is D. proliferation and differentiation.

natali 33 [55]

Answer:

Fungi indirectly help the fishes by providing digested organic nutrients to their prey insects.

Explanation:

According to the given information, fishes are predators of insects. These insects feed on dead leaves. The insects are not able to digest the cellulose of dead leaves. Fungi breakdown the dead and decaying leaves and digest the complex molecules such as cellulose into simpler organic nutrients which in turn are consumed by insects.

If fungi do not decompose the dead leaves, insects would not be able to derive the organic nutrients from them. A shortage of food supply to insects would starve them. Unavailability of prey insects would starve fishes. Thereby, fungi indirectly benefit the fishes to obtain their nutrition from the insect.

For water to travel across the cell membrane at a substantial rate the water molecules travel through protein channels known as

Kitty [74]

The appropriate response is Facilitated Diffusion. It is the procedure of unconstrained detached transport of atoms or particles over a natural film by means of particular transmembrane indispensable proteins.
In the cell, cases of atoms that must utilize facilitated diffusion to move all through the cell film are glucose, sodium particles, and potassium particles. They pass utilizing transporter proteins through the cell film without vitality along the fixation slope.
