Question 1

When Daniel Offer and his colleagues studied the self-images of adolescents in the United States,Australia,Bangladesh,Hungary,Israel,Italy,Japan,Taiwan,Turkey,and West Germany,at least _____ percent of the adolescents displayed a healthy self-image.

Accepted Answer

According to the information in the passage, the researchers studied the self-images of adolescents in ten different countries. The passage does not provide a specific percentage for the number of adolescents with a healthy self-image, but it does state that "at least" a certain percentage had a healthy self-image. The only answer choice that fits this description is D, which says at least 73% of the adolescents had a healthy self-image.

Question 2

Which of the following is a type of estrogen?

Accepted Answer

Estradiol is a type of estrogen, which is a female hormone responsible for the development of secondary sexual characteristics, regulation of the menstrual cycle, and maintenance of bone health. Insulin is a hormone produced by the pancreas that regulates glucose metabolism. Testosterone is a male hormone responsible for the development of primary and secondary sexual characteristics. Progesterone is a female hormone that is important for the preparation of the uterus for pregnancy.

Question 3

Fourteen-year-old Kent recently received his blood test results which indicate an eighteenfold increase in testosterone levels and a twofold increase in estradiol over the past few years.It appears that Kent:

Accepted Answer

Kent is experiencing normal changes during puberty. It is typical for testosterone levels to increase significantly during puberty in males, and estradiol levels also increase to a lesser extent as it is a byproduct of testosterone conversion. Therefore, Kent's test results indicate normal hormonal changes during puberty.

Question 4

The mean age at the beginning of the growth spurt in girls is:

Accepted Answer

The mean age at the beginning of the growth spurt in girls is approximately 9 years old. This is an average onset time for the growth spurt associated with puberty in females.

Question 5

For the majority of teens,adolescence is marked by:

Accepted Answer

While there may be some instances of stress and low self-esteem during adolescence, the majority of teens develop a healthy self-image as they navigate this period of growth and change. Delinquency is also not a universal experience for teens.

Question 6

Which of the following is associated with breast,uterine,and skeletal development in girls?

Accepted Answer

Estradiol is the primary female sex hormone responsible for breast, uterine, and skeletal development in girls. Insulin is a hormone produced in the pancreas that helps regulate blood sugar levels. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism. Luteinizing hormone is a hormone produced in the anterior pituitary gland that triggers ovulation in females and testosterone production in males.

Question 7

Which of the following statements is TRUE?

Accepted Answer

Marked weight gains coincide with the onset of puberty for both boys and girls. Option A is incorrect as girls typically experience growth spurts earlier than boys. Option B is incorrect as not all children who are shorter than their peers before puberty will surpass their peers during adolescence. Option C is incorrect as, on average, boys tend to be taller than girls at the end of adolescence.

Question 8

A brain-neuroendocrine process occurring primarily in early adolescence that provides stimulation for the rapid physical changes that take place is called:

Accepted Answer

Puberty is the process of physical changes that occur during adolescence, such as the development of secondary sexual characteristics and the ability to reproduce. This process is primarily driven by a brain-neuroendocrine process involving the hypothalamus, pituitary gland, and gonads. Hormones such as testosterone and estrogen are released during this process, leading to the development of primary and secondary sexual characteristics. Menarche and spermache refer specifically to the onset of menstruation in females and the production of sperm in males, respectively, and are specific events that occur during puberty. Estrogen is a hormone involved in the reproductive process and is released during puberty, but it is not the primary brain-neuroendocrine process that drives physical changes during this time.

Question 9

Which of the following is a more accurate vision of adolescence?

Accepted Answer

While some adolescents may experience rebellion or crisis, it is not a universal experience for all. The majority of adolescents are able to navigate through this stage of life by making important decisions and commitments, while also establishing their sense of identity and place in the world. Juvenile delinquency is not a typical experience for most adolescents, and many do make positive contributions to their communities while successfully transitioning to adulthood. Option A provides a more accurate and balanced view of adolescence.

Question 10

Puberty:

Accepted Answer

The answer of Puberty:
...

Question 11

The growth spurt that characterizes pubertal change occurs approximately _____ for girls than for boys.

Accepted Answer

Girls typically experience their growth spurts around the age of 10-11, while boys experience theirs around the age of 12-13. This suggests that the growth spurt occurs approximately two years earlier for girls than for boys.

Question 12

A girl's first menstruation is called:

Accepted Answer

Menarche is the first occurrence of menstruation in a girl, typically occurring between the ages of 11 and 14. Gonadarche refers to the onset of puberty, including the development of the ovaries, while spermarche refers to the onset of sperm production in boys. Adrenarche is the maturation of the adrenal gland, which can occur before the onset of puberty.

Question 13

_____ is a hormone associated in boys with genital development,increased height,and deepening of the voice.

Accepted Answer

Testosterone is the hormone associated with the development of male sexual characteristics such as genital development, increased height, and deepening of the voice.

Question 14

Which theorist proposed the "storm-and-stress" view that adolescence is a turbulent time charged with conflict and mood swings?

Accepted Answer

The theorist who proposed the "storm-and-stress" view of adolescence is G. Stanley Hall. This view suggests that adolescence is a period of emotional turmoil and conflict. Hall's ideas were influential in shaping early views of adolescent development, but they have been criticized in more recent research for overemphasizing the universality of adolescent experience and neglecting individual differences.

Question 15

Ms.Chang is trying to prepare her health class students for the onset of puberty.What should she tell the boys that they are likely to experience first?

Accepted Answer

The answer of Ms.Chang is trying to prepare her health...

Question 16

Which of the following is typically the last male pubertal characteristic to occur?

Accepted Answer

The answer of Which of the following is typically the...

Question 17

Behind the first whisker in boys and the widening of hips in girls is a flood of _____,powerful chemical substances secreted by the endocrine glands and carried through the body by the bloodstream.

Accepted Answer

The sentence specifically references "powerful chemical substances secreted by the endocrine glands," which are hormones. Amino acids and phospholipids are important molecules in biochemistry but are not referenced in the sentence. While enzymes are also important in biological processes, they are not specifically mentioned in relation to the changes in boys and girls during puberty.

Question 18

The peak rate of pubertal change occurs at _____ years for girls and _____ years for boys.

Accepted Answer

The peak rate of pubertal change occurs at around 11½ years for girls and 13½ years for boys, as per the research findings. So, option (C) is the correct answer.

Question 19

Puberty refers to a period of:

Accepted Answer

Puberty refers to a period of rapid physical maturation involving hormonal and bodily changes that occurs primarily during early adolescence, typically between the ages of 8 and 13 for girls and 9 and 14 for boys. It involves the development of secondary sexual characteristics, such as the growth of breasts and the onset of menstruation in females, and the growth of facial hair and deepening of the voice in males, among other changes.

Question 20

Thirteen-year-old Grace's blood tests indicate that her levels of testosterone are about twice as high as they were a few years ago,and that her estradiol levels are about eight times higher than earlier.Grace is most likely experiencing:

Accepted Answer

Grace is experiencing normal changes during puberty, which can result in significant fluctuations in hormone levels. It is common for testosterone levels to increase in both boys and girls during puberty, and for estradiol levels to increase more significantly in girls, as they begin to develop female physical characteristics. These hormonal changes are typically part of the normal process of sexual development and are not necessarily problematic as long as they remain within a healthy range.
