Answer:
Directional Selection
Explanation:
The type of natural selection that favors one of the extreme phenotypes over the intermediate and another extreme phenotype is called directional selection. Here, the extreme phenotype exhibits better survival and reproductive fitness over the other phenotypic ranges.
In the given example, the frequency of the heat-tolerant allele in microbes is shown to increase under the conditions of higher temperatures of the water of the springs in which they live.
When the temperature of spring water is increased, the frequency of the heat-tolerant allele is reduced and is increased again upon an increase in water temperature.
Since the natural selection favors the extreme phenotype (microbes with heat tolerance) when the spring water exhibits higher temperatures, it is directional selection.
Answer:
<em>The correct option is D) A species that does not normally live in an area.</em>
Explanation:
Non- native species can be described as a species which do not live in a particular habitat but are introduced into the habitat due to certain reasons or causes. The introduction of non-native species might badly affect the stability of an area. The non-native species might fight with the native species for resources like food, water, shelter etc. Sometimes, the introduction of non-native species is done so that the species can feed on any other species which is not beneficial for that environment.
A geographic range of an animal can give us a lot of information, for example:
- the climatic conditions it adapted to: does it like wet or a dry environment? Does it like heat?
-<span>the parasites/predators that these butterflies may encounter - by knowing who else lives in that area, we can guess what </span>can threaten the butterflies
-similarly, we can guess what food is available to the butterflies.
The correct answer is option B.
This shows commensalistic relationship.
What is commensalism?
Commensalism is a biological relationship (symbiosis) in which individuals of one species profit, while those of the other species suffer neither advantages nor disadvantages.
This is in contrast to parasitism, which is related to parasitism in that the parasitoid has a free-living state and eventually kills its host rather than just damaging it, amensalism, where one is damaged while the other is unaffected, and parasitism, where one is harmed and the other benefits.
The host species, which is largely unharmed, may provide nourishment, shelter, support, or means of mobility for the commensal.
