What percent of developing organisms fails to properly implant?
- A.
50 %
- B.
40 %
- C.
60 %
- D.
70 %
Correct Answer
C. 60 %Explanation
60% of developing organisms fail to properly implant. This means that out of every 100 developing organisms, 60 of them do not successfully implant in the appropriate location. This could be due to various factors such as genetic abnormalities, hormonal imbalances, or uterine conditions. Proper implantation is crucial for the development of a healthy pregnancy, so a high failure rate can have significant implications for fertility and reproductive health.Rate this question:

Which of the following happens during the fetal period?
- A.
The indifferent gonad differentiates
- B.
Implantation
- C.
The neural tube forms
- D.
The blastocyst becomes an embryo
Correct Answer
A. The indifferent gonad differentiatesExplanation
During the fetal period, the indifferent gonad differentiates. This refers to the process where the undifferentiated gonads in the developing fetus begin to develop into either male or female reproductive organs. This is an important step in sexual development and occurs around the 7th week of gestation. The differentiation of the gonads is influenced by genetic and hormonal factors, and ultimately determines the individual's biological sex.Rate this question:

Eight-year-olds who had been born very early are more likely than those who were born "full-term" to:
- A.
Have allergies
- B.
Exhibit signs of depression
- C.
Have cerebral palsy
- D.
Suffer from sinus headaches
Correct Answer
C. Have cerebral palsyExplanation
Premature birth is associated with a higher risk of cerebral palsy, a neurological condition that affects muscle control and movement. This is because babies born prematurely may have underdeveloped brains and be more susceptible to brain injuries. The other options, such as allergies, signs of depression, and sinus headaches, are not directly linked to premature birth. Therefore, the correct answer is that eight-year-olds who were born very early are more likely to have cerebral palsy.Rate this question:

Advances in which area are critical in attaining the age of viability?
- A.
Lung functioning
- B.
Heart functioning
- C.
Weight gain
- D.
Brain functioning
Correct Answer
D. Brain functioningExplanation
Advances in brain functioning are critical in attaining the age of viability because the brain plays a crucial role in the development and functioning of all other organs and systems in the body. It controls vital functions such as breathing, heart rate, and temperature regulation, which are necessary for survival outside the womb. Additionally, the brain is responsible for cognitive and sensory processes, allowing the baby to interact with the environment and respond to stimuli. Therefore, the development and proper functioning of the brain are essential for a baby to reach the age of viability.Rate this question:

Which of the following statements about teratogens is true?
- A.
All teratogens increase the risk of damage
- B.
In order to be teratogen, a substance must always cause damage
- C.
The placenta screens out most harmful substances
- D.
Alcohol was the first teratogen to be formally identified
Correct Answer
A. All teratogens increase the risk of damageExplanation
All teratogens increase the risk of damage. Teratogens are substances that can cause harm to a developing fetus, leading to birth defects or other developmental issues. While the extent of damage may vary depending on the specific teratogen and the timing and duration of exposure, all teratogens have the potential to increase the risk of damage to the developing fetus. It is important for pregnant individuals to avoid exposure to known teratogens to minimize the risk of harm to their baby.Rate this question:

Why are women encouraged to stop using recreational drugs prior to pregnancy?
- A.
Most recreational drugs interfere with fertility
- B.
The embryonic stage is a critical period for physical structure and form
- C.
Both alcohol and tobacco have been associated with incomplete implantation
- D.
Genetic susceptibility to teratogens is greatest during the embryonic period
Correct Answer
B. The embryonic stage is a critical period for physical structure and formExplanation
During the embryonic stage, the baby's physical structure and form start to develop. This is a critical period because any interference or damage during this time can have long-lasting effects on the baby's health and development. Therefore, women are encouraged to stop using recreational drugs prior to pregnancy to ensure that the baby's physical structure and form develop properly without any interference or harm caused by the drugs.Rate this question:

A term that refers to the result of a combination of teratogens is:
- A.
Genetic vulnerability
- B.
Critical period
- C.
Interaction effect
- D.
Kangaroo care
Correct Answer
C. Interaction effectExplanation
An interaction effect refers to the combined impact or influence of multiple factors or elements. In the context of teratogens, an interaction effect would indicate that the harmful effects observed are not solely due to one teratogen, but rather the result of the interaction between multiple teratogens. This suggests that the combination of these teratogens has a more significant or different effect than each teratogen individually.Rate this question:

Jean and Sean are dyzygotic twins whose mother drank alcohol throughout her pregnancy. Jean shows symptoms of fetal alcohol syndrome but Sean does not. The likely explanation for this difference between the twins is:
- A.
Jean's circulation absorbed more alcohol from the mother's blood than did Sean's
- B.
A teratogen's effects vary depending on when exposure occurs
- C.
Females are more vulnerable to prenatal alcohol exposure
- D.
A teratogen may or may not be harmful depending on the individual's genetic makeup
Correct Answer
D. A teratogen may or may not be harmful depending on the individual's genetic makeupExplanation
The likely explanation for the difference between Jean and Sean is that a teratogen, such as alcohol, may or may not be harmful depending on the individual's genetic makeup. This means that while Jean may have been more susceptible to the harmful effects of alcohol due to her genetic makeup, Sean may have had genetic factors that protected him from these effects. This highlights the importance of considering individual differences when it comes to the impact of teratogens during pregnancy.Rate this question:

Antiviral drugs:
- A.
Can prevent prenatal transmission of HIV
- B.
Are highly teratogenic
- C.
Have been shown to increase the rate of spontaneous abortion
- D.
Interfere with brain development
Correct Answer
A. Can prevent prenatal transmission of HIVExplanation
Antiviral drugs can prevent prenatal transmission of HIV by reducing the viral load in the mother, which in turn reduces the risk of transmission to the fetus during pregnancy, labor, and delivery. These drugs work by inhibiting the replication of the virus, thus decreasing the chances of the baby acquiring the infection. This prevention strategy has been proven effective in reducing the transmission rate and improving the health outcomes for infants born to HIV-positive mothers.Rate this question:

The spontaneous onset of labor at approximately 266 days after conception is set in motion by:
- A.
Intervention by the mother's physician
- B.
Fetal hormones that pass into the mother's circulation
- C.
Rupture of the amniotic tissue
- D.
Stretching of mother's cervix by the fetal head
Correct Answer
B. Fetal hormones that pass into the mother's circulationExplanation
Fetal hormones that pass into the mother's circulation are responsible for the spontaneous onset of labor at approximately 266 days after conception. These hormones trigger a cascade of events in the mother's body, including the release of prostaglandins, which help to soften and thin the cervix, and oxytocin, which stimulates contractions of the uterus. This hormonal signaling from the fetus to the mother's body plays a crucial role in initiating the labor process.Rate this question:

What is the worst and most prevalent cause of SGA (small for gestational age)?
- A.
Tobacco
- B.
Caffeine
- C.
Cocaine
- D.
Alcohol
Correct Answer
A. TobaccoExplanation
Tobacco is the worst and most prevalent cause of SGA (small for gestational age) because smoking during pregnancy restricts the oxygen and nutrient supply to the fetus, resulting in poor growth and development. The harmful chemicals in tobacco can also lead to placental abnormalities and increase the risk of preterm birth. Studies have consistently shown that smoking during pregnancy is strongly associated with SGA, making it a significant factor in causing this condition.Rate this question:

The primary reason that adolescent mothers often have small babies is:
- A.
Maternal malnutrition
- B.
The mother's young age
- C.
Inadequate immunizations
- D.
Premature birth
Correct Answer
A. Maternal malnutritionExplanation
Adolescent mothers often have small babies due to maternal malnutrition. During adolescence, mothers are still growing themselves and their bodies may not have enough nutrients to support the growth and development of the fetus. This can result in restricted fetal growth and low birth weight. Maternal malnutrition can also lead to other complications during pregnancy, such as preterm birth. Therefore, the lack of proper nutrition in adolescent mothers is the primary reason for small babies.Rate this question:
