Biology

Answer:

A population of mosquitoes develops resistance to a pesticide

Explanation:

Evolution can be defined as the way the characteristics of a species change over several generations. This process relies on natural selection - a mechanism in which individuals that are better adapted to their environment survive and reproduce most successfully.

A population of mosquitoes developing resistance to a pesticide is an example of adaptation. This is how mosquitoes become adapted to their environment and increase their chances of survival. Eventually, most of the mosquitoes will be resistant thanks to natural selection. This is how mosquitoes evolve.

This is why the fourth option is the correct one.

What was a mining process that removed large quantities of earth.
jasenka [17]

Answer:

Open-cast mining

Explanation:

The aftermath of open cast mining are pits (called quarries) on the surface of the earth where the surface soil has been removed/ displaced to access the mineral deposits that are just close or at the surface of the earth. This type of mining results in environmental degradation because they disturb the biodiversity of the ecosystem in which the mining is taking place. Rehabilitation of the area is required after the mining has been exhausted to restore the initial environment.

Nadusha1986 [10]

Answer:

The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:

Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.

These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.

What is the role of salmon with respect to shrimp in this food chain?
suter [353]

Salmon are predators to shrimp.

This makes sense because a predator is an animal that hunts another animal to survive. Since salmon feed on shrimp, they must be a predator.

Additionally, we can eliminate the other possibilities by process of elimination:

-B is incorrect as a parasite is an organism that lives inside of another organism. Since salmon do not live inside of shrimp, this doesn't make sense.

-C is incorrect because a host is an organism that a parasite lives inside of. Since shrimp do not live inside of salmon, this also can be removed.

-D is incorrect because prey is an animal that is eaten by another animal. Since shrimp to not eat salmon, this can also be eliminated.

Therefore, A is our answer.

Hope this helps! :)
