Explanation:In the central nervous system, the supporting cells are collectively referred to as neuroglia.
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).
<span>The most likely means by which the zoospores spread from one free-living amphibian to another is via the flagella. The flagella is a tail-like structure on zoospores that helps them to move.</span>
<span>The cell cycle is divided into two main parts interphase and mitosis. Mitosis is when the cell divides and this process is taken up by the process of dividing. Interphase is broken down into several phases: G1, growth occurs (cytoplasm increases); S, DNA synthesis (replication) occurs; and G2, growth occurs (cytoplasm increases and organelles are replicated).
So the answer is b) Cytoplasm increases, and organelles and DNA are replicated</span>
