C. Bursting of an animal cell in hypotonic solution
D. Shrinking of the protoplasm away from the cell wall in a hypertonic solution
Answer: Option D
Solution (By JKSSB Mock Tests)
Plasmolysis occurs when a plant cell is placed in a hypertonic solution, causing water to leave the cell by exosmosis, leading to shrinkage of the protoplasm and its detachment from the cell wall. Incipient plasmolysis is when protoplast just starts to pull away. Opposite is deplasmolysis (when placed in hypotonic solution). Swelling is turgidity. Animal cells undergo crenation or lysis.
Explanation:
Cortisol (a glucocorticoid) from the adrenal cortex is a steroid hormone derived from cholesterol. Insulin and growth hormone are peptides, adrenaline is a catecholamine (amino acid derivative).
Explanation:
Spermatogenesis is the process of formation of sperm cells (spermatozoa) from undifferentiated spermatogonia. This process occurs exclusively in the seminiferous tubules, which are highly coiled tubes located within the testes. The epididymis is where sperm mature and are stored, and the vas deferens transports them.
Explanation:
Catalase is an antioxidant enzyme found in peroxisomes that efficiently decomposes hydrogen peroxide (a toxic byproduct) into water and oxygen. Lipase digests fats, amylase starch, pepsin proteins.
