Answer:
<h2><u>
directional selection</u></h2>
Explanation:
This type of natural selection is referred to as . In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.

Answer:
The heat sensitive polymerase would be denatured resulting in formation of little or no PCR products.
Explanation:
PCR is a technique that forms multiple copies of a small DNA sample. For the purpose, the DNA sample is exposed to very high-temperature conditions (around 95 degrees C) to facilitate the denaturation of DNA helix. These high-temperature conditions denature enzymes such as heat-sensitive DNA polymerases. Therefore, no or very little DNA molecules will be formed by the end of the process as the denatured DNA polymerase would not be able to extend the primers.
To avoid these conditions, heat-tolerant Taq polymerase is used in PCR which can withstand the extremely high-temperature conditions of PCR.
The correct answer is (c) Don’t leave your tap running while brushing your teeth, shaving, or washing the dishes. Fix leaky faucets and pipes right away.
As seen in the bar graph that huge amount of water is wasted in the domestic ways. By using the water in adequate amount and saving the water that is wasted while running the tap while brushing and fixing the leaks as soon as possible will save a huge amount of water. The bar graph is covering maximum wastage of water from these sections only. By reducing the water used in brushing, leaky faucets and others can save maximum water.
