Negative feedback in reflex loops __________. is responsible for triggering the response to the stimulus is "negative" because i

Biology

Answer:

is common because it promotes homeostasis

Explanation:

The negative feedback loop is a mechanism wherein a change in some condition stimulates a response to counteract the changed condition and thereby, the homeostasis is restored.

For example, an increased blood glucose level above its homeostatic level stimulates the secretion of insulin hormone from the pancreas which in turn stimulates the absorption of glucose from the blood into the cells (specifically the liver and muscle cells) and thereby restores the normal blood glucose levels.

Most of the processes in the human body are regulated by negative feedback loops to maintain the homeostasis.

Which statement concerning osmosis and active transport is correct?
marshall27 [118]

The question is incomplete, however, the statements associated with this question is given in the comments and here as well:

Neither facilitated diffusion nor osmosis requires cell energy.

Diffusion of gases and other small molecules requires no energy on the part of the cell.

Active transport requires cell energy and osmosis doesn't.

Both endocytosis and active transport require cell energy.

Answer:

The correct answer is - Active transport requires cell energy and osmosis doesn't.

Explanation:

Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.

In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.

Describe the relative locations of the following bacterial cell components:
Dovator [93]

Answer:

A. outside plasma membrane:

1. cell wall   6. flagella

B. outside of the cell

4. fimbriae   5. pilus

C. in cytoplasm

2. nucleoid   3. ribosome

Explanation:

Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.

The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.

Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.
