3. The presence of Malaria in many countries has been eradicated and even in parts of Africa, the incidence of Malaria has been

reduced substantially. Without endemic malaria from Africa, the sickle cell mutation is purely disadvantageous. What do you think will happen to the percentage of people carrying the Sickle Cell gene over time under the pressures of natural selection

Answer:

The percentage of people carrying sickle cell gene increases.

Explanation:

People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body. When the malarial parasite attacks on the cells of the body, the molecular machinery for cleaning up the waste is already present in the body.  Those places where malaria is common, the people having sickle cell because the sickle cell show resistance against malarial disease.

A bird species that migrated from riverbanks in South America to the northern hemisphere were responsible for pollinating a plan
aniked [119]

Answer:

Gene flow would decrease as a result of the alteration of migration patterns. Therefore, the variability of this species would decrease.

Explanation:

Gene flow refers to the<u> transfer or introduction of genes from one population to another</u>. Gene flow enables the introduction of new alleles, therefore increasing biodiversity.

The rate of gene flow between groups of species depends on different factors. For instance, gene flow increases with the ability of a species to move from one place to another and, at the same time, on the possibility of migrating species mating with resident species. This occurs not only with birds but even with humans, when they migrate from one country to another, which increases diversity and variability.

Therefore, <u>if the migration patterns of birds that pollinate a plant species from South America is altered, then there would be less variability within this plant and also with this bird species.</u>

How is it possible for white dwarfs to have a lower luminosity than the sun even though it is much cooler?
ratelena [41]

Answer:

White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.

Explanation:

As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.
