Describe how DNA is coiled and eventually supercoiled to condense it into chromosomes.
Solnce55 [7]

Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging. DNA can be further packaged by forming coils of nucleosomes, called chromatin fibers. These fibers are condensed into chromosomes during mitosis, or the process of cell division.

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

During DNA packaging, long pieces of double-stranded DNA are tightly looped, coiled, super coiled, and folded so that they fit easily within the cell.  This highly compacted DNA is then arranged into structures called chromosomes.

Answer:

Carbon starts as coal or oil in the earth, then is brought up by mining or drilling. When brought up, it is used up and the gases go into the atmosphere. Trees, soil and water act as carbon sinks, which suck up all the carbon from the air and contain it. When carbon is absorbed by the soil, it goes back into the ground.

Ghella [55]

Answer:

Option B

Explanation:

The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.

Hence, option B is correct
