The chemical process that is happening is called fermentation.

<u>Explanation:</u>

Grapes contain a lot of carbohydrates, specially maltose. Maltose is a disaccharide, composed of two molecules of glucose. This maltose, when acted upon by yeast produces ethanol. The process going in is called fermentation. Here one molecule of glucose undergoes the process of glycolysis which leads to formation of two molecules of pyruvate.

These pyruvates are acted upon by alcohol dehydrogenase to form two molecules of ethanol and two molecules of carbon dioxide. Thus we can see bubbles coming out of the solution. Yeasts die as the alcohol concentration reaches around 13 to 14% v/v.

1. In pea plants, tall (T) is dominant to dwarf (t). Show the cross
MA_775_DIABLO [31]

Answer:

Tt - 2/4 = 1/2 or 50%            Heterozygous TALL

tt - 2/4 = 1/2 or 50%             Homozygous Dwarf

Explanation:

So let's make a Punnett for this so you can see what the outcome is yourself:

Tall is <u>dominant</u> - T

Dwarf is <u>recessive</u> - t

Heterozygous means that they have one of each allele. The genotype of one parent would be then Tt.

***It is heterozygous tall because Tall is a dominant trait so if it is accompanied by the recessive trait dwarf, then the Tall allele would mask it.

The other parent is a dwarf plant. The genotype would then be tt.

*** Now for a recessive trait to appear, it should not have a dominant trait mixed with it, which could mask it. The result then is homozygous recessive or homozygous Dwarf.

So now that we know the genotypes of the parent plants, we can put it into a Punnet:

    t      t

T  Tt   Tt

t   tt    tt

As you can see, out of the 4 outcomes we have:

Tt - 2/4 = 1/2 or 50%            Heterozygous TALL

tt - 2/4 = 1/2 or 50%             Homozygous Dwarf
