Answer:The extent of variety in the genetic information in the population of offspring.
Explanation:C is correct
Answer:
<em>The more the diversity in a location, the more is the diversity in organisms. </em>
<em></em>
Explanation:
Every area has a specific environment which is favorable for the survival of particular species adapted to live in that environment.
If there is such diversity in North California's environment, we will find that the population of beetles will be abundant in areas which are favorable for the survival of the beetle population. It may happen that with the passage of time, the beetle population might evolve and adapt to live in other areas too. Changes in habitat makes species diversity favorable.
Answer:
A. spiral galaxies are not pinwheel-shaped
Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
