 Question 17

Why do most women choose to have general prenatal screening before deciding whether or not to have more invasive testing?

·         Because prenatal screening can be done before the baby is born, but the invasive testing can only be done after birth.

·         It can only have negative effects when consumed through patterns of binge drinking.  

·         It can lead to problems with the kidneys, bones, and heart, that go away after birth.

·         The universal patterns of behavior and cognitive processes that are different between humans and animals

 

 Question 23

What is the difference between a sperm and an egg?  

·         The sperm is the female gamete, while the egg is the male gamete.  

·         The sperm contains only Y chromosomes, while the egg contains both X and Y chromosomes.  

·         The sperm causes monozygotic twins, while the egg causes dizygotic twins.  

·         The sperm is the male gamete, while the egg is the female gamete.
