LuckyWell [14K]

Answer:

Negative feedback.

Explanation:

The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Question 4
Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in  separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.

- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

  • <em><u>Bacteria</u></em><em> is a prokaryotic organism. </em>
  • <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles. </em>
  • <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
