Answer:
d) transcriptional factors
Explanation:
Gene expression in developing organisms is regulated on several different levels. In many developing animals, regulation of gene expression is influenced by the action of Hox genes. Transcriptional factors regulatory elements is produced by many Hox genes.
Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA and Hox genes help lay out the basic body forms of many animals, including humans, flies, and worms. They set up the head-to-tail organization.
Correct answer: Mitochondria
Mitochondria is found in all eukaryotic cells and it perform very important function inside the cell. It is also known as the power house of the cell.

It serves as a site for cellular respiration and ultimately generate energy for the cells from the food we eat to carry out activities and process of the body such as cell division, cell death and growth.

Answer:
Answer in explanation
Explanation:
The article by the author is an interesting read and contains a whole lot of facts.
The main point the author is driving at is that the ozone hole is getting a kind of healing from its otherwise thought depletion continuation.
What he is trying to say is that, although over the years there has been a rate of decline in the layer, a recent study has shown that the decline rate has in fact slowed down and the hole thought to be on regular depletion is in fact getting healed at a rate in which the depletion has slowed
