What is natural selection? How does this work on organisms in nature? (should be at least 3 sentences)
BigorU [14]

Answer:

The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange.  If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.

An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population

Explanation:

That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.

Anyway, goodluck.

CORRECT ANDSWER GETS BRAINLIST
marusya05 [52]

Answer:

A) Power plant

Explanation:

The key to understanding this question, is first knowing what "stationary" means. When something is stationary, it doesn't move, it just stays in one place.

Since power plants are buildings, they naturally don't move. On the other hand, the other choices are all vehicles that are intended to move. So while all of these options do cause air pollution, the power plant is the only one that is stationary.

I hope this answer helps you :)
