Which mutation scenario will always lead to natural selection?(1 point)
Responses
a mutation causes a specific advantage within the population
a mutation causes a specific advantage within the population
a mutation causes a specific variation within the population
a mutation causes a specific variation within the population
a mutation causes a gene to become inactivated
a mutation causes a gene to become inactivated
a mutation causes an inactivated gene to be reactivated
a mutation causes a specific advantage within the population will always lead to natural selection. This is because individuals with this advantageous mutation will have a higher chance of survival and reproduction, passing on this mutation to their offspring and increasing its frequency in the population over time.

Which characteristic describes an independent clause?
A. It includes a subject and a verb and can stand alone.
B. It expresses an incomplete thought.
C. It is a group of words containing a subject or a verb but not both.
D. It describes the action in a sentence and cannot stand alone.
The characteristic that describes an independent clause is:
A. It includes a subject and a verb and can stand alone.
An independent clause is a group of words that can stand alone as a sentence because it contains both a subject and a verb and expresses a complete thought. It can also be combined with other clauses to form more complex sentences.
The correct answer is: "a mutation causes a specific advantage within the population."
To understand why this is the correct answer, let's first explain natural selection. Natural selection is the process by which certain traits or characteristics become more or less common in a population over time, based on how well they enable organisms to survive and reproduce.
Mutations, which are changes in an organism's DNA, are the raw material for natural selection. Some mutations can give individuals an advantage in terms of their survival and reproductive success, while others may have no effect or even be detrimental.
In the case of the first response, "a mutation causes a specific advantage within the population," this scenario describes a mutation that introduces a beneficial trait or characteristic. This advantage would increase the likelihood of survival and reproduction for individuals with that mutation, allowing them to pass on the mutation to future generations. Over time, this mutation would become more common in the population through natural selection.
The other response options do not necessarily always lead to natural selection. While variations within a population (option 2) or inactivation of a gene (option 3) can occur through mutations, they may not necessarily confer an advantage or disadvantage. Additionally, the reactivation of an inactivated gene (option 4) may or may not result in natural selection, depending on whether the reactivated gene provides a selective advantage.
So, to summarize, a mutation that causes a specific advantage within a population is the scenario that will always lead to natural selection.
