the respiration rate will increase as temperature increases. An increase in temperature will minimize the amount of dissolved oxygen in the water and increase the metabolic rate of the goldfish, thus causing the goldfish's respiration rate to increase (“Hot waters make it hard for fish to breathe”).
Answer:
When air pollution began, it caused acid rain, damaging and destroying forests. It caused animals to become ill and potentially die as the acid rain ruined their environment. The air pollution also made around 400,000 people die faster than they would without air pollution.

The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
