The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
Answer:
D
Explanation:
1. As given, the overall genome contain 50% G+C.
And the concept is that G is always pairs with C.
and A is always pairs with T.
So, in a dsDNA, A+G= T+C
2. As there that, there is a cluster of genes comprising about 20,000 bp that is 64% G + C so this so that the 20,000 bp segment is a recent acquisition via horizontal gene transfer.
Chloroplasts
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
