Explanation:

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

Why do we exist? Very hard question...
STatiana [176]

Answer:

We exist to see if we can past the test God gives us through our lifetime here on Earth. We exist because God put us here on Earth, with the first man being made of clay, and the first woman being made of the clay from the ribcage of the man.

Explanation:

We face many tests in our lives, whether we notice them or not. We are then given praises for passing tests and gain sins for failing tests and doing wrong.

Tests can come in many ways, such as picking up something that someone dropped, being polite, controlling anger, staying focussed, and more.

Epistasis is the interaction between genes such that one gene influences or interferes with the expression of another gene, lead
Sophie [7]

Answer:

Pigmented snails: A_B_; albino snails: A_bb, aaB_, aabb

This is an example of recessive epistasis. In recessive epistasis, two recessive alleles mask expression of an allele at a different locus. The 9:7 ratio observed in this question is a special case of epistasis called duplicative recessive epistasis, which means the presence of either aa or bb was sufficient to mask expression of the other gene. In this case, if snails had two copies of either allele a or allele b, pigment production was suppressed, resulting in albino individuals.

In a population of pea plants, green peas are the result of a homozygous recessive condition. If the frequency of the allele for
kompoz [17]

Answer:

32%

Explanation:

Since the population is in Hardy-Weinberg equilibrium, the allele and genotype frequencies will remain constant over generations.

The frequency of the recessive allele (q)= 0.20

Since p+q= 1

so, p= 1-q

and p=1-0.20= 0.80

The frequency of heterozygous genotype (2pq) = 2 x 0.20 x 0.80 = 0.32 or 32%

Therefore, the expected frequency of heterozygous genotype in the next generation would be 32%.

I would believe it is the Ozone but since it’s not an option the Ferrel Cell is the westerlies and the polar cell is the polar easterlies. So, I would say go with 4! Hope this helps, goodluck! xoxo.
