Correct Answer: All of the above
Explanation:
Gastrulation rearranges the cells of the blastula and ultimately forms the three germ layers of the embryo. The primary layers that will form all of the major body and organ systems of the organism, these germ layers include the ectoderm, mesoderm, and endoderm.
Correct Answer: Thyroxin
Explanation:
Thyroxin or Thyroxine is the thyroid hormone that regulates carbohydrate metabolism in the human body.
Correct Answer: E
Correct Answer: Ilium
Correct Answer: Tetrad
Explanation:
Tetrad is a homologous chromosome pair in the given options. A homologous chromosome pair is a pair of chromosomes one from father and one from mother that has same gene sequence after the process of meiosis.
Correct Answer: They increase amplitude as they move away from the stimulus point
Explanation:
Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-none.
