The three stages of prenatal development, in order from earliest to latest, are the embryonic stage, the fetal stage, and the germinal stage.
What is wrong in this statement?
The order is incorrect. The correct order is germinal stage, embryonic stage, and fetal stage.
Children raised in single-parent families are automatically made to experience behavioral issues.
Is this Myth or Fact, and why?
Myth. Family structure can pose challenges, but the child development depends far more on the quality of parenting, economic stability, and emotional support than the structure of the family alone.
Which stage of prenatal development covers the period from week 9 until birth, during which the fetus grows rapidly and finishes developing organs?
A) Germinal stage
B) Embryonic stage
C) Fetal stage
C) Fetal stage
When a 3-week-old has his cheek gently stroked by his mother, he automatically turns his head toward that side and opens his mouth. Which reflex is the baby demonstrating, and how does it help him survive?
Rooting reflex: it helps the baby to find the nipple and drink the mother's milk.
What is a harmful exposure that interferes with prenatal development?
A Teratogen
The rooting reflex occurs when a baby automatically grasps an object that is placed directly into the palm of their hand.
What is wrong in this statement?
The description is not for the rooting reflex. (The rooting reflex is turning the head toward a gentle touch to feed)
If both of your biological parents have brown eyes, it is genetically impossible for you to be born with blue eyes.
Is this Myth or Fact, and why?Myth. Brown eye color is dominant, but both parents can carry a hidden gene for blue eyes.
When a newborn baby is laid on their back and turns their head to one side, extending the arm on that side while bending the opposite arm, which reflex are they demonstrating?
A) Palmar grasp reflex
B) Asymetrical Tonic neck reflex
C) Moro reflex
D) Stepping reflex
B) Asymetrical Tonic neck reflex
Both of Sarah's biological parents are tall, but Sarah grew up eating a very poor, nutrient-lacking diet and ended up much shorter than her parents. what is affecting her heredity to be tall?
Her parents gave her the potential to be tall, but her poor diet kept her from reaching that height. Not only the genes are necessary, the environment also matters.
What is the difference between genotype and phenotype?
The genotype is the genetic instructions in DNA; the phenotype is the observable expression of that code (physical traits, behavior, personality)
A genotype refers to a person's visible physical traits, like eye color, personality and height, while a phenotype refers to their hidden genetic code.
What is wrong in this statement?
The definitions are swapped.
Drinking moderate amounts of alcohol during pregnancy is completely harmless to a developing fetus.
Is this Myth or Fact, and why?
Myth. Alcohol is a known teratogen; no amount is proven safe during pregnancy.
The genetic transmission of characteristics from biological parents to their descendants is known as:
A) Mutation
B) Heredity
C) Adaptation
D) Environment
B) Heredity
A pregnant woman avoids eating certain types of fish because she knows the baby’s organs are forming rapidly during this early period. Which specific prenatal stage (zygote, embryo, or fetus) is most vulnerable to these exposures?
Embryonic stage. This is when major organs and body structures have a fast and critical development.
What is the difference between phylogeny and ontogeny?
Phylogeny is the history of species over time; ontogeny is the development of one individual from conception.
Contraception methods are used during prenatal development to ensure that the embryo receives adequate nutrients through the umbilical cord.
What is wrong in this statement?
Contraception is used before conception to prevent pregnancy, not during prenatal development.
Primitive infant reflexes disappear during a baby's first year as their brain matures.
Is this Myth or Fact, and why?
Fact. As the brain develops, muscles move voluntarily, and early reflexes start to fade away.
What type of family is formed when two single parents marry and combine their children into one house?
A) Nuclear family
B) Extended family
C) Blended family
D) Single-parent family
C) Blended family

What is the specific name of the reflex where the baby closes the limps around an object and begins making sucking movements with the mouth and tounge?
Sucking reflex
A nuclear family consists of children living with their parents, grandparents, aunts, and uncles all under the same roof.
What is wrong in this statement?
That describes an extended family, not a nuclear family. A nuclear family consists only of parents and their children.
Family planning includes deciding the timing and spacing of children, not just using birth control.
Fact. Family planning covers reproductive goals like deciding when to have kids, economic situation and emotional state.
Which of the following is a key goal of family planning programs?
A) Helping individuals decide when and if to have children
B) Curing genetic diseases before birth
C) Eliminating the need for prenatal care
D) Guaranteeing a specific gender for their kids
A) Helping individuals decide when and if to have children
A couple just got married. The woman wants to live with her husband, grandparents, her siblings and wants to have kids, while the man doesn't want to have kids. Which two tipes of families do they want?
Woman: extended family
