Answer:
It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.

Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Explanation:
Answer:
The correct answer:
1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)
2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)
Explanation:
As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).
Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:
1. 100 × 35/100 ⇒ 35% of 100
2. 200 × 25/100 ⇒ 25% of 200
Answer:
Telophase
Explanation:
During telophase, a nuclear envelope becomes apparent around the nucleolus of each sister chromatid, forming their nucleus before separation/cytokinesis.
