5. Generation III

6. Yes

7. No

8. 8 and 9

Explanation:

5. Males are depicted by square symbols. The most squares are found in generation III (4 males) so this is the answer.

6. Carriers are heterozygotes, which means they have one copy of the sickle cell allele. Let's imagine the normal allele is A and the sickle cell allele is a. A cross between two carriers is Aa x Aa. Here are the possible genotypes:

A a

A AA Aa

a Aa aa

Individuals with an aa genotype have sickle cell disease. So 1:4 children of two carriers will have the disease.

7. Normal h0m0zygous individuals have the genotype AA. It is not possible for them to have an affected child, because the child will always inherit one of the A alleles from that individual (it does not matter whether they inherit A or a from the other parent, their genotype can only be Aa or AA, which are both unaffected.

8. We are looking for two affected individuals in the same family. We will be able to see they are affected because their symbols will be shaded. Individuals 8 and 9 are both heterozygous (carriers) and have 4 children. 2 affected and 2 unaffected.

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.
