Answer:
The correct answer will be option-D
Explanation:
In case the blood pressure drops in the body, the juxtaglomerular cells of the kidney start converting the prorenin into renin. This renin converts inactive angiotensin to angiotensin I which gets converted to angiotensin II by ACE enzyme.
The angiotensin II acts as vasoconstrictor narrowing the vessels and thus increasing the blood pressure. It also stimulates the secretion of aldosterone which increases the reabsorption of sodium ions and help increase the blood pressure of the blood.
Thus, option-D is the correct answer.

Answer:
oxytocin
Explanation:
The pituitary gland is a small gland that divides into two distinct portions, the anterior and posterior lobes, and is located at the base of the brain.
The anterior pituitary, also known as the adenohypophysis, secretes six important peptide hormones, they are:
- The growth hormone;
- Adrenocorticotropin;
- The thyroid stimulating hormone;
- Prolactin;
- Two gonadotropic homons - FSH and LH;
Oxytocin is not a hormone produced by the anterior pituitary but by the posterior pituitary, which is known as the neurohypophysis.
Answer:
Statement A - cellular membrane
Statement B - eukaryote
Statement C - spore
Statement D - prokaryote
Explanation:
The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.
Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.
Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.
An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.
