Answer:

D) a population's allele frequencies change over a span of generations.

Explanation:

Microevolution occurs within a population whereby gene flow, mutation, genetic drift or natural section brings about a change in a population’s allele frequencies over several generations. It occurs on a small scale. Examples of microevolution can be observed in resistance being evolved by pests to pesticides. i.e. Mosquitoes developing resistance against DDT. Mosquitoes with genes that can withstand DDT have evolved overtime.

In most animals, the ______ state of the life cycle is much larger than the ______ state.
Alexxx [7]

In most animals, the diploid state of the life cycle is much larger than the haploid state.

<h3>What is life cycle?</h3>

The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.

The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.

During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.

For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.

Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

Drag the tiles to the correct boxes to complete the pairs.

Answer:

Denitrification = bacteria convert nitrates into nitrogen gas.

Denitrification occurs when nitrogen is removed from the soil and this happens when bacteria concert nitrites back to Nitrogen gas.

Nitrification = Bacteria convert ammonia to nitrites and nitrates.

Nitrification is the process by which bacteria concert ammonia made from ammonification into useful organic compounds like nitrites.

Nitrogen fixation = bacteria break down waste products and return nitrogen to the soil.

Nitrogen fixation is when bacteria return nitrogen to the soil by breaking down waste products that fall into the soil.

Ammonification = bacteria convert atmospheric nitrogen to ammonia.

During ammonification, bacteria converts nitrogen compounds to Ammonia or Ammonium.

Assimilation = Plants and animals take in and use nitrogen compounds.

Assimilation then occurs when plants take in these nitrogen compounds and use them. Animals will get these compounds by eating the plants.
