A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of the bacteria to break down and digest organic molecules in the environment. Bacteria with this mutation are better able to find and utilize food sources. According to the theory of natural selection, what is MOST likely to occur in future generations of this bacteria?A)The relative frequency of the mutation will increase as time passes.
B)Because the mutation has changed the DNA of the bacteria, a new species will be formed.
C)Because the mutation is abnormal, the mutation will become more rare with every passing generation.
D)Bacteria with the mutation will increase in number until the food supply is exhausted, causing the bacteria to become extinct.

Answers

Answer 1
Answer: The answer is A) The relative frequency of the mutation will increase as time passes. 

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. So, the mutation could not be abnormal, since it helps bacterial survival. Also, the bacteria will not extinct because of this mutation nor the new species will be formed since this is not so big mutation.
This leaves A) as the right answer. The relative frequency of the mutated allele will increase since the more bacteria with the mutation will survive and it will be passed down to the new generation over time.

As the human population grows _____.

Answers

Explanation:

Whenever there will be increase in population of living beings then there will be increase in amount of needs or requirements.

For example, when population was only 50% then use of natural resources was about 50%. But when population increased by 70% then there will be 20% increase in use of natural resources as compared to earlier consumption.

As a result, there will be decrease in quantity of resources.

Therefore, we can conclude that as the human population grows there will be increase in consumption of resources.
resources will go down... there is an awesome video on youtube about this btw
