<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>
Answer:
On January 22, 2001, EPA adopted a new standard for arsenic in drinking water of 0.01 mg/l or 10 parts per billion (ppb), replacing the old standard of 50 ppb. Water systems had to meet the new standard by January 23, 2006.
Explanation:
I think it’s “a Protein molecule”
A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of <u>evolutionary genetics.</u> The mutation will lead to <u>all the bacteria becoming resistant to the antibiotic.</u><u> </u>
Genetic evolution :
Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.
The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection. Through mutations that alter the biological targets of antibiotics or by obtaining resistance genes from other bacteria, microorganisms can develop resistance to antibiotics.

Answer:
Phototrophs
Explanation: Some organisms obtain their energy from the sun by the process of photosynthesis. These organisms are known as phototrophs because they can make their own organic molecules using sunlight as a source of energy.
