Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
Most bacterias are heterotrophs. Meaning they can't make their one good ( sadly :3)
Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.
Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate. As, heart rate of most people will be higher 30 minutes after they drink a cup of coffee is testifying the fact, that higher heart rate is related with caffeine intake.
Therefore, hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Answer:</h2>
The term is <u>solar wind</u>.
<h2>
Explanation:</h2>
The breezy particle which is produced from the corona region of the sun is called as Solar wind. It is made up of electrons, protons and alpha particles with kinetic energy. Implanted inside the sunlight based breeze plasma is the interplanetary attractive field.
The sun oriented breeze shifts in thickness, temperature and speed after some time as the sunlight changes. Its particles can get away from the Sun's gravity on account of their high vitality coming about because of the high temperature of the crown, which is caused due to source of origin called corona.
