Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.

A option i.e; glucose breaks down into ATP without any initial energy input. (It just spontaneously happens) does not make sense to make while all other are correct. So, the best option will be the A. because A option is not true about ATP.
Answer:
One pair of homologous chromosomes.
Explanation:
One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
1. Scientist remove plasmids, small rings of DNA, from bacterial cells
2. An enzyme cuts open the plasmids DNA. The same enzymes removes the human insulin gene from its chromosomes
3. The human insulin gets attaches the open ends of the plasmids to form a closed ring
4. Some bacterial cells take up the plasmids that have the insulin gene
5. When cells reproduce, the new cells will contain copies of the engineered
plasmids. The foreign gene directs the cell to reproduce human insulin.
