Summary Introduction
To determine: The effects of FAS on all the individuals and not only on the children born with this syndrome.
Introduction: FAS stands for fetal alcohol syndrome. Teratogens are agents or chemicals which cause fetal and/or embryonic abnormalities. Alcohol acts as a teratogen causing fetal alcohol syndrome. Consumption of alcohol during pregnancy is one of the major causes of FAS. Alcohol-related birth defects are milder forms of this disorder.

- During pregnancy, how does malnutrition during critical periods of development affect the fetus? Group of answer choices When the development of an organ is impaired, the damage is irreversible. If the development of the heart is impaired in the early stages, it can be reversed if good nutrition is provided after the critical period. Malnutrition does not affect the fetus but has adverse effects on the mother's health. Malnutrition does not cause dental problems as teeth develop after the baby is born. A surplus of nutrients taken after the critical period will make up for a deficit caused at any time during development.arrow_forwardThe development of sex and gender is a good example of a developmental cascade because: Group of answer choices Although having an X and a Y chromosome at conception typically leads to the development of testes during prenatal development, this may not lead to typical male genitalia if certain hormones are present later in development Two people may have the same gonads early in prenatal development but end up with different external genitalia and gender identities as a result of differences in the prenatal environment All of the options listed here are correct Having two X chromosomes at conception typically leads to the development of ovaries during prenatal development, which typically leads to high levels of estrogen in puberty, which typically leads to a female gender identity in adulthoodarrow_forwardWhich developmental stage is mismatched? a. second week—implantation b. third week—heart development begins c. fourth and fifth week—limb buds appear d. sixth through eighth week—all organ systems present e. None of these stages are mismatched.arrow_forward
