c-they leave the nucleus and are scattered throughout the cell.
d-homologous chromosomes do not pair up until division starts.

Blood is pumped to the lungs from the right side of the heart, always leaving the heart from the ventricle ... so it's the right ventricle.
Memory trick: the heart pumps blood RIGHT to the lungs. Then all that's LEFT is the rest of the body.

B. During interphase, DNA is in its usual uncoiled form which is called chromatin.
