1. a wide variety of factors. heat, climate, weather, natural disasters that lower the population of prey animals, etc
2. well and example is this: it is getting hotter in Antarctica, causing the ice caps to melt. this change would make it harder for prey animals like penguins to find somewhere to live, thus making them easier food for predators. such as killer whales and polar bears.
3. the more trees we cut down to make room for buildings, for instance, causes many animals habitats to dissapear, the animals shortly after
Answer:
A
Explanation:
The correct answer would be that <u>the spores inherit half of their genes from each parent.</u>
<em>The ascospores start their journey through the fusion of 2 haploid nuclei (karyogamy) to form a diploid zygote nucleus. The zygote nucleus develops and then divides by meiosis to produce 4 haploid daughter cells. Each daughter cell then divides mitotically, making it eight haploid nuclei at the end.</em>
Hence, each spore inherits half of its gene from different nuclei.
The correct option is A.
Answer:
E) founder effect and genetic drift
Explanation:
Dunkers moved to Pennsylvania and inhabited a new area to develop a new population. This new population might not have the same gene pool and the same allele frequencies for all the genes as present in the original population. The change in the allele frequencies of a population due to the colonization of a new area by a few members is called the founder effect.
The small size of the new population of Dunkers present in Pennsylvania was more likely to be affected by any chance event which could have added more uniqueness to their gene pool. This is called genetic drift. Therefore, the genetic uniqueness of their population from all the other populations and from their original population might be the result of founder effect and genetic drift.

I'm sitting in school right now I cannot really answer the rest.
Answer:
Symbiosis and decomposers.
Explanation:
The ants feed on both plants and insects so we can say that ants are omnivorous. They make a symbiotic relationship of mutualism with fungi such as mold which helps the ants to breakdown the cellulose of plants whereas plants provide habitat to fungi. The bacteria feeds on the dead body of ants and release nutrients by performing the function of decomposition so bacteria acts as decomposer so in that way these four organisms interact with each other.
