Question

Identify incorrect combinations among the following

• A. I & II
• B. II & III
• C. III & IV
• D. IV & II

Hint:

It is important to recognize the biological roles of enzymes and processes, such as how hyaluronidase aids in fertilization and how secondary spermatocytes divide in the formation of spermatozoa.

Answer 1

The Correct Option is D

The given combinations are related to biological terms. Let's analyze each one:

1. Hyaluronidase is an enzyme that is released by the acrosome, and its function is to dissolve the zona pellucida of the egg during fertilization. This combination is correct.
2. Placenta is an organ that plays a role in increasing the availability of glucose and amino acids to the fetus. It also facilitates the exchange of gases and waste. This combination is correct.
3. Hypnone is a substance related to the somatic mesoderm and splanchnic mesoderm, giving rise to the pericardial cavity. However, Hypnone does not play a role in this function. This combination is incorrect.
4. Secondary spermatocyte undergoes Meiosis II and forms a large spermatozoa with a small polar body. This combination is correct.

Conclusion: The incorrect combination is Hypnone (Option D), as it does not play a role in the given mesodermal function.
