Answer:
some traits become more common, others less. ... The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature's chances of living longer and producing more offspring).

Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
The answer is biological evolution.
The theory of biological evolution explains how organisms evolved during the time. It explains how the characteristics of different species changed over generations. According to the theory, most of current species developed from some distinctly different species that have lived a long time ago.
b. protozoa
One of the four species of protozoan in the genus Plasmodium is responsible for the acute or subacute infectious disease known as malaria.
<h3>A virus or a bacteria causes malaria?</h3>
- A virus or bacteria cannot cause malaria.
- Plasmodium, a parasite that often spreads through infected mosquitoes, is what causes malaria.
- A mosquito consumes Plasmodia that are present in blood when it feeds on an infected human.
<h3>How do protozoa cause malaria?</h3>
- The female anopheles mosquito bite is the primary method of transmission of malaria, a protozoan infection of the red blood cells.
- The Plasmodium genus of protozoa is what causes malaria.
- Four different types of malaria parasites can infect people: Plasmodium malariae, vivax, ovale, and falciparum
