Answer:
mutations can be either beneficial or harmful depending on the environment
Explanation:
Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.
Because 12 is considered more basic, you would add a more acidic solution to buffer it.

Answer:
Yes
Explanation:
Of the many functions of protein in your body, one of its most critical is supporting your immune system. The immune response protects you against harmful microorganisms, including viruses and bacteria, as well as foreign substances that might attack your defenses, such as a thorn or flames from a fire.
Answer:
A. True
Explanation:
We continuously use drugs and antibiotics against the micro organisms. In the course of time, some microbes may develop resistance against these antibiotics by bringing changes or modifications in their structures. Those which become resistant, survive the selective pressure and hence selected by the nature. Hence developing drug resistance by microbes is also an example of natural selection.
Similarly herbicides and pesticides resistance developed in weeds and pests respectively after prolonged use of herbicide and pesticide is also an example of natural selection which supports the process of evolution.
