A set of instructions that describes how that person will look and grow are called:
Correct Answer
C. Genes
Explanation
Genes are the correct answer because they are responsible for carrying the instructions that determine an individual's characteristics and growth. Genes are segments of DNA that are passed down from parents to offspring and contain the information needed to produce proteins, which ultimately determine traits such as eye color, height, and hair texture. Therefore, genes can be seen as the "blueprint" or set of instructions that describe how a person will look and develop. Heredity refers to the passing of traits from parents to offspring, sex cells are involved in reproduction, and while a blueprint can be a metaphorical term for genes, it is not the scientific term used.
3.
The passing down of traits from parents to children is known as:
Correct Answer
B. Heredity
Explanation
Heredity refers to the passing down of traits from parents to children. It involves the transmission of genetic information, which is carried by genes. Therefore, heredity is the correct answer as it encompasses the concept of genes and genetics in the context of passing down traits.
4.
Your appearance and personality may be influenced by:
Correct Answer
D. Genetics & environment
Explanation
Both genetics and environment play a significant role in shaping a person's appearance and personality. Genetics refers to the inherited traits and characteristics passed down from parents, which can determine physical features, such as eye color or height, as well as certain personality traits. On the other hand, the environment encompasses the external factors that an individual is exposed to, including upbringing, cultural influences, and life experiences. These environmental factors can also shape appearance and personality, as they contribute to the development of social skills, behavior patterns, and personal preferences. Therefore, a combination of genetics and environment influences how a person looks and behaves.

It plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as promoting secondary sexual characteristics like muscle mass, bone density, and facial hair growth. Estrogen is primarily a female sex hormone, and while hormones are produced by the testicles, testosterone specifically refers to the male sex hormone produced by them. Therefore, the correct answer is testosterone.
19.
Another word for the menstrual cycle is:
Correct Answer
C. Period
Explanation
The correct answer is "period" because it refers to the recurring monthly process that happens in the female reproductive system, where the lining of the uterus sheds and is expelled through the vagina. It is commonly known as the menstrual cycle and is characterized by bleeding and hormonal changes. The other options, such as "egg," "sperm," and "ovum," are not synonymous with the menstrual cycle and do not accurately represent the concept.
20.
A woman can get pregnant when a sperm reaches the ovum (egg).
Correct Answer
A. True
Explanation
When a sperm reaches the ovum (egg), fertilization can occur, leading to pregnancy. This is a biological process where the genetic material from the sperm combines with the genetic material from the egg, resulting in the formation of an embryo. Therefore, it is true that a woman can get pregnant when a sperm reaches the ovum.

22.
The only sure way to prevent pregnancy or STD's is to remain abstinent.
Correct Answer
A. True
Explanation
Abstinence is the only foolproof method to prevent pregnancy or sexually transmitted diseases (STDs). By choosing not to engage in sexual activity, individuals eliminate the risk of both unintended pregnancies and the transmission of STDs. While other methods such as contraception and condom use can significantly reduce the risk, they are not 100% effective. Therefore, the statement that the only sure way to prevent pregnancy or STDs is to remain abstinent is true.
23.
Abstinence means refraining from sexual activity until marriage.
Correct Answer
A. True
Explanation
Abstinence refers to the practice of abstaining from any form of sexual activity until marriage. This means that individuals who choose to practice abstinence will not engage in any sexual behavior, including intercourse, until they are married. This decision is often motivated by personal, cultural, or religious beliefs. By choosing abstinence, individuals aim to prevent unwanted pregnancies, sexually transmitted infections, and emotional complications that may arise from engaging in sexual activity outside of a committed marital relationship. Therefore, the statement "Abstinence means refraining from sexual activity until marriage" is true.
24.
The female reproductive sex organ is known as the:
Correct Answer
C. Ovaries
Explanation
The correct answer is ovaries. The ovaries are the female reproductive organs responsible for producing eggs and releasing hormones such as estrogen and progesterone. They are located on either side of the uterus and play a crucial role in the menstrual cycle and fertility. The menstrual cycle refers to the monthly process in which the uterus prepares for pregnancy, and it is regulated by the ovaries. Testicles are the male reproductive organs, semen is the fluid containing sperm cells.
25.
Ovaries produce the females sex hormone known as:
Correct Answer
A. Estrogen
Explanation
Ovaries produce the female sex hormone known as estrogen. Estrogen plays a crucial role in the development and regulation of the female reproductive system, including the growth of secondary sexual characteristics, regulation of the menstrual cycle, and maintenance of pregnancy. It also has effects on various other organs and tissues in the body. Testosterone is primarily produced in the testes and is the primary male sex hormone, while "hormones" is a general term that encompasses various chemical messengers produced by different glands in the body.
26.
The menstrual cycle happens when the females egg is not fertilized.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the menstrual cycle is a natural process that occurs in females of reproductive age. It involves the shedding of the uterine lining and the release of an unfertilized egg from the ovaries. If the egg is not fertilized by sperm, it passes through the uterus and is expelled from the body during menstruation. This cycle typically occurs every 28 days, although it can vary from person to person. Therefore, it is true that the menstrual cycle happens when the female's egg is not fertilized.
27.
