Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
The method of virus transmission which results in a greater spread of disease is through airborne transmission
All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.
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
