Answer:
<em>The correct option is A) The sundew population would increase. </em>
Explanation:
Organisms in a community interact with one another in some way or the other.
In the above-mentioned example, sundews and wolf spiders of a community are in competition with each other for food resources. If the population of one of the species i.e wolf spider decreases this means that there would be lesser competition for food resources. As a result, there will be more food present for the sundews. Hence, the population of sundews would increase if the population of wolf spider decreases.
Answer:
Most people experience increased infant mortalities at high altitudes due to the inability of the mother to provide sufficient oxygen to the developing fetus but now variation in the DNA sequence in the people that lives at higher altitudes like in Tibetans allow normal level of infant survival at high altitudes.
This variation occurred in the EPAS1 gene in the Tibetan population that is responsible for delivering oxygen more efficiently to the fetus. This nucleotide variation is also present in low landers of Beijing but natural selection selected the variant gene in Tibetan people because they require this mutated gene for their survival.
So the population passed this variant gene in next-generation, therefore, inheritance allowed the spreading of the mutated gene to the next generation therefore by natural selection and inheritance a mutated gene spread through a human population that had just begun living high in the mountains.
