Answer:
The correct option is D. potentially interacting populations of different kinds of organisms.
Explanation:
In biology, a community can be described as the different populations of organisms that live in a certain habitat at a certain period of time.
For example, consider a habitat where there are a different type of trees, different types of plants, different types of animals, different types of decomposers. All these populations of different organisms will make a community. All the organisms in a community interact with one another in some way or another.
The answer is similarly; similar environments.
<span>Convergent evolution suggests different organisms evolved <u>similarly</u> due to <u>similar environments</u>. </span>
Convergent evolution is a phenomenon of independent evolution of
similar traits in species that are in different lineages. These traits are
similar in form or function but were not present in the last common ancestor of
those species.
There are many examples of convergent evolution among plants and
animals.
Among the plants, both cactus and euphorbia are succulent plants, have
spines, live in the deserts, but they belong to the different families.
Among the animals, dolphin, which is a mammal, is more similar to fish, than to other
mammals. Or, both birds and bat, which is the mammal, have wings.
So, all these
examples of convergent evolution suggest that the living in the similar
environmental conditions led to development of similar forms between distinct
species.

Answer:
d. pxp +2pq
Explanation:
The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:
p² + 2pq + q² = 1
where, p = dominant allele
q = recessive allele
Here,
p² represents frequency of homozygous dominant genotype
2pq represents frequency of heterozygous genotype
q² represents frequency of homozygous recessive genotype
Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
