Explanation:
The frequency of the recessive allele for the Hbs gene when there is an outbreak of malaria will increase.
The sickle hemoglobin is produced by the HbS gene, a variation of the B-globin gene. A person who possesses two recessive alleles is said to have the genetic condition known as sickle cell anemia.
People who are heterozygous have the advantage of having normal and sickle hemoglobin, so they are more resistant to malaria because malaria will only act on normal hemoglobin, increasing the prevalence of the recessive allele of the HbS gene.
However, the malarial parasite only affects hemoglobin which is normal, making heterozygous people more resistant to the disease. Hence, the frequency of the recessive allele for the Hbs gene when there is an outbreak of malaria will increase.

The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.
<h3>What is the smallest contractile unit within skeletal muscle?</h3>
A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.
In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

Answer:
<u>Generate new ideas</u>
<u>There are many branches of science</u>
Explanation:
Of course many would agree that science has become our way of life, it shapes how we work; by enabling us to generate new ideas. For example, one famous idea that was generated as a result of science is the electric lightbulb by Thomas Edison. Just think of how the world would have been if there weren't any light bulbs to beautify our cities.
Also, science has many branches; making it a very interesting field of study. The major branches include life science, physical science, and earth science.
