1. What is the main organ of the male reproductive system?
Correct Answer
A. Testicle
Explanation
The testicle is the main organ of the male reproductive system. It is responsible for producing sperm and testosterone, the primary male sex hormone. The testicles are located in the scrotum and are responsible for the production, storage, and transportation of sperm. They play a crucial role in fertility and the overall reproductive function of males.

2. It is the main organ of the Female Reproductive System.
Correct Answer
C. Ovary
Explanation
The ovary is the main organ of the Female Reproductive System. It is responsible for producing and releasing eggs for fertilization. The ovaries also produce female sex hormones, such as estrogen and progesterone, which regulate the menstrual cycle and maintain the health of the reproductive system.
3.
It is the phase of the menstrual cycle which is referred to as a woman's monthly bleeding.
Correct Answer
B. Menstrual Phase
Explanation
The correct answer is Menstrual Phase. This phase refers to the time during a woman's menstrual cycle when she experiences bleeding. It occurs when the lining of the uterus sheds, resulting in the release of blood through the vagina. This phase typically lasts for a few days to a week and marks the beginning of a new menstrual cycle. During this phase, hormone levels are low, and the body prepares for the next phase, which is the follicular phase.

3. What part of the Male Reproductive System is also known as the sperm duct?
Correct Answer
C. Vas deferens
Explanation
The vas deferens is known as the sperm duct in the male reproductive system. It is a long, muscular tube that connects the epididymis to the urethra. It carries mature sperm from the epididymis to the urethra during ejaculation. The vas deferens plays a crucial role in the transportation of sperm for fertilization.

4. It is the process where the mature egg is released from the ovary.
Correct Answer
B. Ovulation
Explanation
Ovulation is the process where the mature egg is released from the ovary. This occurs approximately once a month in women of reproductive age. During ovulation, the egg is released into the fallopian tube, where it can potentially be fertilized by sperm. If fertilization does not occur, the egg will disintegrate and be shed along with the uterine lining during menstruation. Ovulation is a crucial step in reproduction as it allows for the possibility of fertilization and pregnancy.

5. What is the female sex/ reproductive cells?
Correct Answer
A. Egg cell
Explanation
The female reproductive cells are known as egg cells, or ova. These are produced in the ovaries and are necessary for sexual reproduction. The egg cell is the largest cell in the human body and is capable of being fertilized by a sperm cell to create a new life. Estrogen is a hormone produced by the ovaries that plays a crucial role in the development and regulation of the female reproductive system. The uterus is the organ where a fertilized egg implants and develops into a fetus. Option 5 is not provided, so it cannot be considered as a possible answer.

6. It is the male hormone responsible for the changes that happen during puberty?
Correct Answer
B. Testosterone
Explanation
Testosterone is the male hormone responsible for the changes that occur during puberty, such as the deepening of the voice, growth of facial and body hair, and development of muscles. It is produced primarily in the testicles and plays a crucial role in the development and maintenance of male reproductive tissues and secondary sexual characteristics. Estrogen, on the other hand, is the primary female sex hormone, while progesterone is involved in the menstrual cycle and pregnancy. The testicle is the male reproductive organ responsible for producing sperm and testosterone.

7. It is called to the first three months of the baby inside the mother's womb.
Correct Answer
A. Embryo
Explanation
The correct answer is embryo. The question is asking for the term used to refer to the first three months of a baby inside the mother's womb. During this early stage of development, the baby is called an embryo. The term fetus is used to refer to the later stages of development, after the first three months. Zygote refers to the fertilized egg, and newborn refers to a baby that has just been born.

8. The changes that happen during puberty is controlled by a part of the brain called the __________.
Correct Answer
Hypothalamus
Explanation
During puberty, the body undergoes various changes such as growth spurts, development of secondary sexual characteristics, and hormonal changes. The hypothalamus, a region in the brain, plays a crucial role in controlling these changes. It releases hormones that stimulate the pituitary gland to produce other hormones, such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are responsible for the maturation of reproductive organs and the onset of menstruation in females. The hypothalamus also regulates the production of other hormones like testosterone and estrogen, which are essential for the development of secondary sexual characteristics.

9. It is the process where the egg and the sperm unite.
Correct Answer
Fertilization
Explanation
Fertilization is the process in which the egg and the sperm come together to form a zygote, which is the first stage of a new individual. During fertilization, the sperm penetrates the egg and their genetic material combines, resulting in the formation of a fertilized egg. This process is essential for sexual reproduction in many organisms, including humans.
11.
10. It is the lining of the uterus that shed if the egg is not fertilized by the sperm.
Correct Answer
Endometrium
Explanation
The endometrium is the lining of the uterus that thickens every month in preparation for pregnancy. If the egg is not fertilized by sperm, hormonal changes occur and the endometrium sheds, resulting in menstruation. This shedding is a natural process that occurs in the menstrual cycle.
