The haploid human genome is approximately 3200 Mbp in size (just looking at one of each pair of chromosomes). Currently we think

there are about 20,000 genes in the (haploid) human genome. Using these numbers, about how many genes on average are in 1 Mbp of human DNA

Answer:

on average, in 1 Mbp of DNA there are 6.25 genes

Explanation:

If a direct proportionality between the size of the human genome and the amount of genes is assumed, we can make a simple rule of three to calculate the number of genes in 1 Mbp, as follows:

3200 Mbp------------------20000 genes

1 Mbp-------------------------x genes

Clearing the x:

x genes = \frac{(1 Mbp)x(20000 genes)}{3200 Mbp}=6.25 genes

Which two statements describe the
Goryan [66]

The two statements which describe the production of soy sauce.

Option A. When soy sauce is made, yeast and mold help break down the sugars to produce various acids.

Option F. To produce soy sauce, yeast and a type of mold are added to a  

mixture of soybeans, wheat, and salt.

Explanation:

Soy sauce is naturally prepared by artisanal brewing and fermentation. The basic ingredients used are soybeans, wheat and salt.

During the brewing process, microbes like mold, yeast or bacteria are added to the basic mixture to ferment. When mold is added to the basic mixture, it ferments and forms a mixture called koji.

Molds like Aspergillus soyae called the koji starter is commonly used. The enzymes present in the mold break the starch in the soy beans and wheat into simpler sugars, and proteins into amino acids, and fats into simpler lipids.  

The koji is then treated with yeast and lactic acid bacteria which ferments the koji and forms the moromi which is then processed further to form soy sauce.

The enzymes of the yeast converts the simple sugars into alcohol, CO2 and other organic acids and elements which enhance the flavor of the sauce. Lactic acid bacteria takes the role of converting the sugars into organic acids like aspartic and glutamic acid, and other amines.
