The faster a cheetah can run, the more likely it is to capture its prey. Cheetahs with longer legs are able to run faster than t
stealth61 [152]

Answer:

D

Explanation:

This is the more likely explanation, as there must be a limit to leg length in an animal that has to run very fast and strain their muscles and bones to the limit to do so.

As for the other options, there is no evidence to conclude that the genes that are involved in cheetahs leg length do not undergo mutation because the population exhibits a variety of leg lengths. Neither can we conclude that there are any isolated subgroups in the pupulation. Natural selection does act upon the traits involved in predation, as the question starts by saying that the faster a cheetah can run the more likely it is to capture its prey.

adoni [48]

Answer:

Disruptive selection

Explanation:

According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.

From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.

According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.

Which practice provides the Best means of protecting biodiversity inthe wild for future generations?? a Initiating recycling pro
PtichkaEL [24]

Answer:

Practice that  provides the best means of protecting biodiversity in the wild for future generations is - <u>expanding breeding programs for endangered species .</u>

Explanation: The best way of preserving biodiversity for future generations in the wild -

  • <u>Expanding breeding programs for endangered species . -:</u> Breeding programmes, such as the panda, help conserve endangered species. Replanting hedgerows because there is greater biodiversity in them than the fields they surround, minimizing deforestation and the release of greenhouse gases, protecting and creating new endangered ecosystems, often by making National Parks.

The other statements are not so suitable means of protecting biodiversity in the wild for future generation as  the first statement indicates about the initiation of recycling programmes in neighborhood , which has no role in preservation of biodiversity or wildlife because the statement is about keeping the environment clean and healthy .

The other statement is about reduction of air pollution as buying vehicles with reduced carbon emissions improves the quality of air.

And the other statement of  Protecting wildlife areas such as national parks comes under the other statement which states "expanding breeding programs for endangered species".

Hence , the correct option is D.
