The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
Answer:
Five examples of real-life situation that show a sequence are given as follows;
1) The progression from class to class in nursery, primary, and secondary
2) The annual increase in population of a country
3) The growth rate of living things
4) The annual weather cycles
5) The variation of temperature with altitude in the Earth's atmosphere
Answer:
d. Two of the above explanations are correct.
Explanation:
A frameshift mutation is commonly known as a genetic mutation that occurs as a result of the indels such as the addition or removal of certain nucleotides in the sequence of a DNA that is indivisible by three. In the presence of addition or removal, the reading frame from the initial translation to a different one. Thus, the correct option is option d.
The reproductive system is a group of sex organs that work together for the purpose of sexual reproduction. Hope this helped!
