Question 1

Which statement concerning the timing of puberty in males and females is true?

Accepted Answer

C

Question 2

Primary sex characteristic changes are those directly impacting

Accepted Answer

Primary sex characteristics are the physical changes directly involved in reproduction, such as the development of the reproductive organs. Therefore, changes in primary sex characteristics are those that impact reproduction directly.

Question 3

Menarche is to spermarche as _____ is to _____.

Accepted Answer

Menarche refers to the onset of menstruation in females, while spermarche refers to the first ejaculation in males. Therefore, the best choice to complete the analogy is A, where onset of menstruation is to ejaculation.

Question 4

A sex difference during puberty involves the fact that ____ is greater for girls than boys.

Accepted Answer

During puberty, girls tend to have a greater increase in body fat compared to boys. This is due to changes in hormonal levels and is a normal part of female development. Boys, on the other hand, tend to experience a greater increase in muscle development during puberty. Lung and heart capacity can vary between individuals and are not necessarily tied to sex differences during puberty.

Question 6

Menarche is best described as the onset of

Accepted Answer

Menarche refers to the beginning of menstruation, which is the shedding of the uterine lining that occurs on a monthly basis in females. It typically signals the onset of puberty. While pubic hair growth and body growth are also often associated with puberty, they do not define the beginning of menstruation.

Question 7

____ is best defined as physical changes that mark the transition from childhood to young adulthood.

Accepted Answer

Puberty is the process of physical changes in the body that mark the transition from childhood to young adulthood. It is characterized by hormonal changes that lead to the development of secondary sexual characteristics, such as breast development in females and growth of facial hair in males. Menopause, on the other hand, is a natural biological process that occurs in women as they age and marks the end of reproductive capacity. Primary and secondary circular reactions are concepts related to Jean Piaget's theory of cognitive development and are not related to physical changes in the body.

Question 8

The answer of Who would be most likely to have...

Question 9

Who is experiencing the first indicator of the onset of puberty in a typical female?

Accepted Answer

Breast development is usually the first physical sign of puberty in females. This typically begins between the ages of 8 and 13, followed by the growth of pubic hair and then menstruation. Ovulation also occurs as part of the menstrual cycle but is not typically considered an indicator of the onset of puberty.

Question 10

Which event defines spermarche?

Accepted Answer

Spermarche refers to the first ejaculation of sperm, marking a significant milestone in male puberty.

Question 11

Who is experiencing the first indicator of the onset of puberty in males?

Accepted Answer

The first indicator of the onset of puberty in males is testicular growth. Therefore, Bandile, whose testes have started to grow, is experiencing the first indicator of puberty. The growth spurt (C) and the growth of pubic hair (B) are also indicators of puberty, but they typically occur after testicular growth has begun. The growth of the penis (D) is another indicator, but it typically occurs after testicular growth and sometimes after the growth of pubic hair.

Question 12

During puberty, changes in physical maturity that are not directly linked to reproduction are referred to as ____ sex characteristics.

Accepted Answer

Secondary sex characteristics refer to physical changes that occur during puberty that are not directly related to reproductive organs, such as breast development in girls and increased muscle mass in boys. Primary sex characteristics, on the other hand, refer to changes in the reproductive organs themselves. Tertiary and instrumental sex characteristics are not recognized terms in the study of human development.

Question 13

The two general types of physical development associated with puberty include

Accepted Answer

Physical changes (such as growth spurts and changes in body composition) and sexual maturation (development of primary and secondary sex characteristics) are the two general types of physical development associated with puberty. Option A is incorrect as lower self-esteem is not a type of physical development. Option C is incorrect as formal-operational thinking is a cognitive development, not a physical one. Option D is also incorrect as lower self-esteem is not a type of physical development and formal-operational thinking is a cognitive development.

Question 14

From whom would you expect the biggest gains in height and weight over the next three years?

Accepted Answer

The answer of From whom would you expect the biggest...

Question 15

The maturation of the ____ during adolescence lags behind the maturation of _____.

Accepted Answer

During adolescence, the prefrontal cortex, which is responsible for self-control, lags behind the maturation of the the limbic system, which is sensitive to reward. This can lead to impulsive and risky behavior.

Question 16

A key physical component of puberty is the ____ gland, which regulates pubertal changes by signaling other glands to secrete hormones.

Accepted Answer

The pituitary gland is responsible for regulating pubertal changes by signaling other glands to secrete hormones such as the adrenal gland and gonads. The thyroid and pineal glands are not directly involved in pubertal changes.

Question 17

In a typically developing adolescent experiencing puberty, you would expect that his or her ____ would be the last body area to grow.

Accepted Answer

The answer of In a typically developing adolescent experiencing puberty,...

Question 18

How many of the following are considered secondary sex characteristics: growth of facial hair in boys, development of a functional uterus in girls, voice change in boys, and broadening of shoulders in girls?

Accepted Answer

Secondary sex characteristics are features that appear during puberty but are not directly involved in reproduction. Growth of facial hair in boys, voice change in boys, and broadening of shoulders in girls are secondary sex characteristics. The development of a functional uterus in girls is not a secondary sex characteristic but a primary one, as it is directly involved in reproduction.

Question 19

Estrogen is directly released by the

Accepted Answer

Estrogen is primarily released by the ovaries in females. It is also produced in smaller amounts by the adrenal gland in both males and females, and by the testes in males. However, the highest levels of estrogen are found in females during their reproductive years, and the ovaries are the main source of this hormone.

Question 20

Which adolescent is experiencing a change in his primary sex characteristics?

Accepted Answer

Kgatello, who has begun to produce sperm, is experiencing a change in his primary sex characteristics, as sperm production is a function of the male reproductive system. The other options - facial hair, deeper voice, and broader shoulders - are all examples of secondary sex characteristics that may develop during adolescence, but they are not directly related to the reproductive system.
