1. Implantation of the fertilized egg normally occurs in the fallopian tube.
Explanation: Implantation of the fertilized egg typically occurs in the uterus, not the fallopian
tube. If it occurs in the fallopian tube, it results in an ectopic pregnancy, which is a medical
emergency.
False
2. Mitosis occurs only in the cells of the reproductive system.
Explanation: Mitosis is a process of cell division that occurs in somatic (non-reproductive) cells
throughout the body, not just in the reproductive system. It is essential for growth, development,
and tissue repair.
False
3. In a normal adult, the malleus, incas, and stapes are located in the inner ear.
Explanation: The malleus, incus, and stapes are actually located in the middle ear, not the inner
ear. They are the small bones that transmit sound vibrations from the eardrum to the inner ear.
False
4. A rapid, involuntary, unlearned, unpredictable response to a stimulus is called a reflex.
Explanation: A reflex is indeed a rapid, involuntary, and unlearned response to a stimulus. It is a
predictable response, such as the knee-jerk reaction.
True
Buds are olfactory receptors.
Explanation: Buds are actually taste receptors, not olfactory receptors. Olfactory receptors are
located in the nasal cavity and are responsible for the sense of smell.
False
Question 6: Neurons are the main cells of the nervous system.
Explanation: Neurons, also known as nerve cells, are the primary cells of the nervous system
responsible for transmitting information throughout the body.
Question 7: Glial cells and neuroglia are the same.
Explanation: Glial cells and neuroglia refer to the same type of cells that support and protect
neurons in the nervous system.
True
Question 8: The male urethra functions in both the urinary and reproductive systems. (It is found
in both males and females.)
Explanation: The male urethra indeed functions in both the urinary and reproductive systems,
allowing for the passage of urine and semen. However, the urethra in females is only part of the
urinary system.
True
Question 9: The fertilization of an egg results in the production of a zygote.

Question 9: The fertilization of an egg results in the production of a zygote.

Explanation: When a sperm cell fertilizes an egg cell, the result is a zygote, which is the initial cell formed during conception.

Question 10: The contractile functional unit of a skeletal muscle cell is the sarcomere. Explanation: The sarcomere is the basic unit of striated muscle tissue responsible for muscle contraction.

Question 11: The largest structure of the brain is the cerebrum. Explanation: The cerebrum is the largest part of the brain, responsible for various higher brain functions, including thought, action, and sensory processing.

Question 12: Neurons generally have one axon and one dendrite. Explanation: Neurons typically have one axon, which transmits signals, and multiple dendrites, which receive signals. However, it is not accurate to say they generally have only one dendrite. False

QUESTION 13 The diploid number is usually 23. Explanation: The diploid number refers to the total number of chromosomes in a cell. In humans, the diploid number is 46, which consists of 23 pairs of chromosomes. False

QUESTION 14 Rods are photo-receptors that are effective in dim light. Explanation: Rods are a type of photoreceptor in the retina of the eye that are sensitive to low light levels and are crucial for night vision.

QUESTION 15 In general, if something is effective for contraception, it is also effective for stopping the spread of disease. Explanation: Contraceptives like condoms can help prevent the spread of sexually transmitted infections (STIs), but other contraceptive methods like birth control pills do not offer protection against STIs. False

QUESTION 16 Locomotion is carried out by skeletal muscles. Explanation: Skeletal muscles are responsible for voluntary movements and locomotion in the body.

Explanation: It is possible for an individual to have both nearsightedness (myopia) and farsightedness (hyperopia) in different parts of the same eye, a condition known as mixed astigmatism. True
