Question 1:

The correct answer is C. Oviduct.

Structure K points to the tube connecting the ovaries to the uterus, also commonly known as the fallopian tube.

Question 2:

The correct answer is A. protect a developing foetus.

Structure L points to the uterus (womb), which is the muscular organ where a fertilized egg implants and develops into a fetus during pregnancy.

Question 3:

The correct answer is B. Muscle.

The uterus is composed primarily of a thick layer of smooth muscle called the myometrium, which allows it to expand during pregnancy and contract during labor.

Question 4:

The secondary sexual characteristics in females (e.g., breast development, widening of hips, growth of pubic hair, onset of menstruation) are primarily controlled by oestrogen.

• A. Progesterone – Mainly involved in the menstrual cycle and maintaining pregnancy; does not drive secondary sexual characteristic development.

• B. Thyroxine – Regulates metabolic rate, not secondary sexual characteristics.

• C. Testosterone – Male sex hormone.

• D. Oestrogen – ✅ Responsible for development and maintenance of female secondary sexual characteristics.

Answer: D. Oestrogen

Question 8:

Let's match the features to egg or sperm:

• Large energy store – Egg (cytoplasm with yolk/lipids for early development).

• Long flagellum – Sperm (for swimming).

• Lots of mitochondria – Sperm (in midpiece for energy to swim).

• Jelly coat – Egg (protects and helps sperm binding).

• Enzymes in the acrosome – Sperm (to digest jelly coat of egg).

Features belonging to the egg: 1 (Large energy store) and 4 (Jelly coat).

✅ Answer: C. 1 and 4

Question 9:

The feature that helps the sperm penetrate the egg is:

5. Enzymes in the acrosome

These enzymes (e.g., hyaluronidase, acrosin) break down the jelly coat and zona pellucida of the egg, allowing the sperm to reach and fuse with the egg membrane.

✅ Answer: feature 5

Question 10:

Fertilization of one egg requires one sperm to fuse with the egg nucleus.

Although many sperm may surround and attempt to penetrate the egg’s layers, only a single sperm successfully fertilizes the egg (polyspermy is prevented by the egg’s cortical reaction).

✅ Answer: D. One
