Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)
Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to
contribute… then the rest works out as follows:
b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett
squares.
Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH
having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore
only has the dominant A and dominant B alleles – no recessive allele possible.

The correct answer will be- true.
Explanation:
The small intestine is the longest part of the gastro-intestinal tract which helps in the absorption of nutrients from the digested food.
The structure of small intestine contains cell membrane extensions called villi and micro-villi which increases the surface area for absorption. The small intestine increases the food absorption by peristaltic movement of the food chyme. The small intestine causes the food chyme to form spirals which passes the food to large intestine.
Thus, true is the correct answer.

Answer:The mother's antibodies can destroy the red blood cells of the fetus.
Explanation:
If a woman with an Rh negative (Rh-) blood group has a child with an Rh positive (Rh +) male, there is a possibility that the child is also Rh +. Although this has no consequences throughout pregnancy itself, as the mother's and fetus's blood does not come into direct contact during pregnancy, it can have serious consequences for subsequent pregnancies.
In fact, rupture of the placenta at the time of childbirth may allow some red blood cells from the fetus to pass into the maternal circulation and cause sensitization, meaning the woman's body will detect them and begin to make anti-human antibodies. Rh that will persist indefinitely in the blood. If a woman regenerates another Rh + child, the anti-Rh antibodies present in her blood will pass easily into the fetus's blood through the placenta and attack and destroy the fetus' red blood cells, which can lead to severe fetal anemia and serious repercussions that sometimes lead to intrauterine death.
