The eggs of the fluke are passed into water supplies from feces and urine of infected people. After hatching the parasite actively swims and invades the body of a snail, usually by penetrating through the snail's foot. The parasite requires the presence of certain species of snails (e.g., Oncomelania, Biomphalaria, Bulinus) to transform (and multiply) itself into an infective stage, called cercaria.
Answer:brown rice
Explanation: Many of the nutrients in brown rice help keep your heart healthy. It's a rich source of dietary fiber, which can reduce your risk of death from heart disease. Brown rice also contains high levels of magnesium, which can help make you less vulnerable to heart disease and stroke.
Answer:
Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>
Explanation:
Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
The answer to this question would be, <span>False.

Answer:
disruptive selection
Explanation:
Disruptive selection -
It is also known as the diversifying selection , it enables to describe the changes in the genetics of the population , in which the trait that is favored is the extreme over the intermediate values .
In case of disruptive selection , the trait variance increases and the population is distributed into two groups .
And , in this case the more individual acquire the peripheral character value in the both ends of distribution curve .
Hence , from the information of the question , the correct answer is disruptive selection .
