Answer:
Jake is correct.
Explanation:
Sophie is wrong because although dolphins and sharks can technically be said to be similar, it resulted from convergent evolution, which has nothing to do with common ancestry and rather to do with similar environments for their homes.
Answer:Bb
Explanation:
Homozygous gene pair are pair of allele that are identical e.g BB
Heterozygous gene pair are pair of allele that are not identical e.g Bb
Heterozygous gene pair could show complete dominance where the Allele for dominant will completely mask the effect of the reccessive allele and the individual will express the trait of the dominant allele.
Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.
<h3>What is
muscle contraction?</h3>
The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.
Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.
