statuscvo [17]

Answer:

b) convolutions

Explanation:

The part that makes the outer rim of the cerebrum is the cerebral cortex. It is composed of gray matter. The billions of neurons of the cerebral cortex are organized in distinct layers. During embryonic development, enlargement of the brain is accompanied by even more enlargement in the gray matter of the cerebral cortex. However, it fits into the skull due to its folds which are also called convolutions or gyri. The cortical region rolls and folds on itself.

The DNA is tightly wrapped around histone proteins in a chromosome why is this packaging necessary?
Luba_88 [7]

Answer:

3.) because the long dna will not fit inside the cell.

Explanation:

This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).

The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.
