Answer:
B
Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.

Both mitosis and meiosis are associated with cytokineses. Mitosis is the same as meiosis if Mitosis happens twice.
Both processes include breaking down the nuclear membrane.
They differ because Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In Meiosis, homologous chromosomes separate leading to daughter cells that aren't genetically identical. In Mitosis, the daughter cells are identical to the parent as well as each other. <span />

Answer:
The correct option is B. aldosterone
Explanation:
In organisms the most important electrolytes from the point of view of their concentration, therefore, of their osmotic effect, are the sodium and potassium ions. Aldosterone is a hormone produced by the adrenal glands, it helps to control blood pressure and it maintains healthy levels of sodium and potassium in the blood, preserving the balance of body fluids and allowing nerves and muscles to function well. The renin hormone, produced by the kidneys, normally stimulates the adrenal glands to release aldosterone.
