An expectant mother with Type Rh-negative blood is safe to accept negative blood. While they can tolerate taking positive blood they can do it only once. After that, they will form Rh antibodies against the Rh+ antigens that they received, and should not accept Rh+ blood again.

True or False?

Explanation:

1. As given here that the women in Rh negative so she does not have antibodies for Rh factor, so first time she can tolerate the Rh positive blood type

2. But after injecting Rh positive blood, there is the generation of Rh antibodies which reject the Rh positive blood if inject once again.

erythroblastosis fetalis: If a woman is Rh negative and the fetus is Rh positive, it can lead to Rh incompatibility and potential complications in the pregnancy.

i think its the first one

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
