Answer:

Tofu and soy oil come from soy bean plants that are grown on farms. Many farmers grow soy beans as cash crops that they can send to places such as tofu processing plants. Soybean plants are legumes. Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well.

This nitrogen cycle that was breifly discussed above is used in what farmers call a crop rotation. Farmers use soybeans and other legumes in roatations with grass crops such as corn or wheat. Grass crops are unable to take their own nitrogen from the air so they either need the nitrogen in the soil that the legumes provide for them in a crop rotation or they need a chemical fertilizer containing nitrogen. Many farmers choose to use both. Most farmers use a two or four year rotation on their fields. In a two year rotation a farmer will alternate a year of a legume such as soybeans and a year of a grass crop such as corn. In a four year rotation a farmer will alternate back and forth between legumes and grass crops just as in a two year rotation, but instead he will use four differnt crops. For example, a farmer may plant a rotation of soybeans, corn, alfalfa (a legume), then wheat (a grass).

The primary function of the chromosome is to?
aleksandrvk [35]

Explanation:

<u>Chromosomes store genetic information. </u>

<u></u>

All the genetic information within the eukaryotic cell is preserved as helical DNA within the nucleus. This DNA is tightly wrapped around histones as chromosomes.

Further Explanation:

DNA sequences contain genes that may have different forms called alleles. The genotype of DNA is transcribed into mRNA and subsequently translated into amino acids that are linked together by rRNA to form proteins that form the phenotype of an organism. Mutations in the DNA sequences affect the corresponding mRNA and therefore the encoded protein

Spontaneous changes that occur within the genome during the cell division process, called mutations. These errors occur as copies of DNA are produced inside the cell; mutations can range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.
