Explanation:
This is the anaphase of mitosis. Anaphase is characterized by the separation of sister chromatids or "pulling away" of the sister chromatids from the metaphase plate to the opposite spindle poles. This is also the phase where chromosomes reach its maximum condensation meaning that the process of the reformation of the nucleus will be shorter and easier.
The carbon cycle moves through virtually all of the earth's spheres.
<h3>Carbon cycle</h3>
There are 4 majors spheres of the earth:
- Atmosphere
- Geosphere or Lithosphere
- Biosphere
- Hydrosphere
The carbon cycle moves through the air (atmosphere), oceans (hydrosphere), organisms (biosphere), and the soil (geosphere).
Thus, the carbon cycle moves through all the spheres of the earth.

Answer;
Complementary base pairs;
- Adenine-Thyamine and Guanine-Cytosine (A-T and G-C)
Explanation;
-According to Chargaf's rule, the secondary structure of the DNA requires that every guanine pairs with a cytosine and every thymine pairs with an adenine, resulting in consistent ratios between the nucleotides.
-In double-stranded DNA, two long molecules twist around one another in a double helix. Pairs of nitrogenous bases are set in the same plane, and interact with each other via hydrogen bonding. These pairs are often referred to as base pairs
