Answer:
Blue eyes is a recessive trait
Explanation:
Recessive traits show in 25% of the offspring, but they skip the first generation. This means that the 25% only shows up in the second generation unless two recessive traits are put together. A likely combination is that both of the parents had Bb, which you can put into a punnet square to visualize.
B b
B BB Bb

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.
Since there was already an anti resistant microorganisms that actuallly have been able to survive through the antibiotics, natural selection states that if one survives and is well adapted to a certain environment, then offspring from that survivor will be created and beneficial traits for the offspring will be received having them a chance for survival. So, the microorganisms spread and spread offspring with that anti resistance in which is the Survival of the Fittest. Until there are no microorganisms that aren’t resistant the lastahas strep throat then returns.
Hope this helps!:)

As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
