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: Euglenophytes
Explanation:
Phosphorescence is a phenomenon associated with an algal division called euglenophytes.
Phosphorescence is a phenomenon when an object is capable of releasing photons of light at a longer wavelength in response to absorbing light of a shorter wavelength. The object releasing the light only releases the light after some time has passed since it absorbed the light of a short wavelength.
Euglenophytes are single-celled plant-like protists that have no cell wall.
Correct Answer: All of the above
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: a segmented genome
Correct Answer: stopping homeostasis from happening
Correct Answer: Intestinal juice
Correct Answer: helps substances pass from the cytoplasm into the nucleus
