Correct Answer: Ribosomes
Explanation:
Protein synthesis take place in the cytoplasm where ribosomes are located as they are the machinery which are responsible for the protein synthesis.
Correct Answer: the volume of the thorax increases.
Correct Answer: Both A & B
Correct Answer: bursting of the host cell
Correct Answer: Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
Explanation:
Aldosterone is a steroid hormone that is produced in the adrenal gland. It is useful and more essential for the conservation of sodium content in the kidney, salivary glands, colon and sweat glands.
Here, Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule is the only option that is NOT correct about aldosterone.
Correct Answer: stopping homeostasis from happening
Correct Answer: Intestinal juice
Correct Answer: helps substances pass from the cytoplasm into the nucleus
Correct Answer: Allows for expansion or contraction of the trachea
Explanation:
Allows for expansion or contraction of the trachea. Hence, so large masses of food can pass through the esophagus during swallowing.
Correct Answer: DNA replicates before the division
