Genotypes Ww and ww, Phenotypes 50% white, 50% yellow

Explanation:

This question involves a single gene coding for wing color in cabbage butterflies. The allele for white wings (W) is dominant over the allele for yellow wings (w). This means that a heterozygous (Ww) will have the white color of wing.

According to this question, if a Ww (white) butterfly is crossed with a ww (yellow) butterfly, the following gametes will be produced by each parent:

Ww - W and w

ww - w and w

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Ww, Ww, ww, we

Ww = white wings (50%)

ww = yellow wings (50%)

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
