Pure water has a pH level of 7, which means it is neutral on the pH scale. If you want to increase the pH of water, you must add an alkaline substance to it. The pH scale ranges from 0 to 14, with anything above 7 being alkaline, and anything below 7 being acidic.
Answer:
The activity that does not represent a beneficial contribution made by biologists is to improve the durability of non-stick coatings (option C).
Explanation:
The development and improvement of non-stick coatings does not correspond to an activity within the field of biology. Anti-stick coatings, such as Teflon, are products developed through industrial activity.
Biologists' activity is focused on living organisms and their interaction with the surrounding environment. Improving arable soils and food quality, as well as increasing life expectancy are activities that fall within the field of study of biology and its related disciplines.

Answer:
$130,410
Explanation:
According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn
Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00
If 1 bushel = $9.00
63 bushels = 63 × 9 = $567
Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.
Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year
Humans have approximately 24,000 genes, but fruit flies are not far behind, with approximately 14,000 genes.
These
instructions that produces a specific protein is called the Gene. A gene is a region
of DNA that encrypts purpose. A chromosome comprises of a long strand of DNA that
involves many genes. A human chromosome can contain up to 500 million base pairs
of DNA that has thousands of <span>genes.</span>
