Answer:
Option (B).
Explanation:
Heart is the main pumping organ of the body. The human heart is divided into four chambers that are right atria, right ventricles, left atria and left ventricles.
The left and right ventricles can easily be distinguished on the basis of their thickness. The right ventricle is less thicker than left ventricle. The thickness of right ventricle is 9mm whereas the thickness of left ventricle is around 40mm.
Thus, the correct answer is option (B).
Answer:
A point mutation
Explanation:
If a point mutation does not change the amino acid, it's called a SILENT mutation. If a point mutation changes the amino acid to a “stop,” it's called a NONSENSE mutation. Deletion and insertion may cause what's called a FRAMESHIFT, meaning the reading frame changes. I know the answer on my own, but this explaination i found on the web is better than my own
I think B I am not sure though. But if I was doing this I would probably pick B. Hope this helps :D
Humans have approximately 24,000 genes, but fruit flies are not far behind, with approximately 14,000 genes.
