Answer:

True because rocks in space collided with earth in the early days

They should separate pure lines (red fan-shaped tails) to cross them with other phenotypes and then observe phenotypic proportion in the offspring. It is Mendelian genetics.

Mendelian genetics refers to the process of observing the phenotypic proportions from a given genetic cross.

Mendelian genetics is always associated with a genetic process known as complete dominance.

Complete dominance occurs when the recessive allele is completely masked in heterozygous individuals.

The correct answer is option Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit as it explains the disadvantage.

A downside of collection circuits is if there may be a ruin or fault at any of the home equipment related to the circuit, the last home equipment could be reduced from the supply. Regarding parallel circuits, home equipment may be related and disconnected to the circuit without affecting different components of it.

if one bulb burns out in a sequence circuit, then this could ruin the circuit. This is due to the fact each tool in a sequence circuit needs to paintings well for the circuit to be complete. Unlike in a parallel circuit - in which every mild has its personal circuit - so despite the fact that one bulb burns out, the last bulbs will nevertheless function.

Hence concluded that  Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit can cause severe damage.

Evidence from countries that continued using DDT showed that correct and timely use of indoor spraying can reduce malaria transmission by up to 90%. In the past, India was able to use DDT effectively to substantially cut the number of malaria cases and deaths.

It also was effective for insect control in crop and livestock production, institutions, homes, and gardens. DDT's quick success as a pesticide and broad use in the United States and other countries led to the development of resistance by many insect pest species.

The two systems in plants that are interacting when sugars are delivered to different parts and when plants respond to light would be transport and response.

Synthesized foods in the form of carbohydrates are transported from sources to sinks in plants through the phloem. This form parts of the material's transportation system in plants generally.

The transported foods are used to generate ATP during respiration. ATP is spent when plants respond to external stimuli such as water, light, objects, etc. Response to external stimuli in plants is known as tropism.

Say this was about breeds of chicken nuggets, some with and some without these features, then we can say that the genotypes of this nugget must be just that, mostly nugget, but due to certain influences, there will be some part that is not just nugget, so:

More than 80% nugget

Less than 20% non-nugget genotype.

This means that the phenotype, that shows up, is something similar to this: a mostly nugget being.

Answer:

the third one

Explanation:

The definition for natural selection is "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. Compare with survival of the fittest (see survival)."

The third question shows us natural selection. Because the population of black mice went up and the tan mice went down. this is an example of natural selection because the black mice have adapted to their environment and reproduced while the tan mice have not.
