Because of genetic variation, a species of beetle has two different body colors, red and green. This species exists in a grassy
pshichka [43]

Answer:

1. Green beetles and red beetles exist in the environment.

2. Birds that eat the beetles move into the environment.

3. Red beetles are eaten by birds, but green beetles aren’t eaten.

4. Green beetles pass on their color trait to future offspring.

5. The entire population of beetles eventually becomes green in color.

Explanation:

According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.

A) planets with long orbits

*all planets in groups 1 and 2 revolve around the sun!
*planets in groups 1 and 2 have moons
*group 2 have the fastest rotations

Our solar system is divided into two sections, the first section being the inner planets consisting of Mercury, Venus, Earth, and Mars.
The second section consists of Jupiter, Saturn, Uranus, Neptune, and Pluto.

The main differences between the two sections are distance from the sun. With the exception of Pluto, All outer planets are massive in comparison to the inner planets.
