- A.

- B.
Otak
- C.

- D.

Correct Answer
B. OtakExplanation
The brain is not an excretory organ in humans. It is responsible for controlling and coordinating various bodily functions, but it does not play a role in the excretion of waste materials from the body. The liver, lungs, and kidneys, on the other hand, are all involved in the process of excretion. The liver helps in the breakdown and elimination of toxins, the lungs eliminate carbon dioxide through respiration, and the kidneys filter waste products from the blood to produce urine.Rate this question:

Rahim
- B.
Ovarium
- C.
Epididimis
- D.
Vulva
Correct Answer
C. EpididimisExplanation
The correct answer is Epididimis. The epididymis is a part of the male reproductive system. It is a coiled tube located on the back of each testicle and serves as a storage and maturation site for sperm. It plays a crucial role in the transportation and development of sperm before they are ejaculated. The other options, such as Rahim (uterus), Ovarium (ovaries), and Vulva (external female genitalia), are not relevant to the male reproductive system.Rate this question:

Proses pembentukan Ovum disebut ??
- A.
Menstruasi
- B.
Spermatogenesis
- C.
Ovarium
- D.
Oogenesis
Correct Answer
D. OogenesisExplanation
Oogenesis is the correct answer because it refers to the process of egg cell formation in females. During oogenesis, the ovum (egg cell) is produced in the ovaries through a series of cell divisions and maturation processes. This process is essential for sexual reproduction in females and is distinct from menstruation, which refers to the shedding of the uterine lining. Spermatogenesis, on the other hand, is the process of sperm cell formation in males, and the term "ovarium" simply refers to the female reproductive organ where oogenesis takes place.Rate this question:

Therefore, both Komodo and kadal are examples of living fossils.Rate this question:
