The best answer is B.
Infectious diseases whose incidence has increased in the past two decades or threatens to increase in the near future have been said to be "emerging''. Such diseases include the following:
1. Old infections emerging as a result of antimicrobial resistance in known agents or break down in public health measures.
2. New infections resulting from change or evolution of existing organisms.
3. Known infections spreading to new geographical areas or population.
4. Previously unrecognized infections in areas undergoing ecologic transformation.
Answer:
Option A, 30 C
Explanation:
Plants are able to produce oxygen through the process of photosynthesis and photosynthesis is well carried in the presence of light at a warm temperature of 28 degree Celsius. The rate of photosynthesis falls if the temperature rises above 28 degree Celsius and with falling rate of photosynthesis, rate of oxygen production also falls.
The rate of photosynthesis and hence the oxygen produces also falls when the temperature falls below 28 degree celsius.
Since, the nearest temperature range is 30 degree celsius thus option A is correct
I found this in a website, “A mutation is a change in DNA, the hereditary material of life. ... So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.”

The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
