Answer:

Bb and Bb

Explanation:

Let B be the allele of a black color;  &

Let b be the allele of a white color

Allele B is dominant over allele b, and as such it masks the expression of allele b

If we have a cross between two heterozygous individuals

i.e Bb × Bb

we have:

               B                b

B              BB             Bb

b              Bb              bb

From above, Phenotypically;

we have the following offspring:

BB  ;   one normal black color

2 Bb:  two heterozygous for black color

bb : one white color

The color ratio is in the ratio of 3 black :1 white  which is synonymous to 10 black : 3 white

So; we can therefore conclude that the genotype of the parents are :

Bb and Bb

You are researching a cytoplasmic protein associated with a nerve disorder. The native form of the enzyme appears to be globular
kherson [118]

Answer:

This signifies that the protein primarily comprises multiple polypeptide chains connected together with the help of disulfide bonds. The enzymes may be found in the form of dimers, trimers, or tetramers. Various examples of dimers, trimers, and tetramer proteins are known, of them, NEMOs dimers are considered to be held by disulfide bonds.  

Thus, it can be hypothesized that the enzyme under examination is a multimer held in combination by disulfide bonds, with each comprising catalytic sites. On breaking of disulfide bonds, the enzyme dissociates into its many single units.  

This illustrates the reduction in catalytic activity. Each active site in a single unit will work, however, at a gradual rate. This also shows detection of multiple globular proteins after disulfide reduction.

Gre4nikov [31]

Answer:

I like how the cheetah has a really pretty coat of spots and speckled with really makes it stand out and look different. I also like that the cheetah is lightning fast, but it's sad it can only run 60-70 miles per hour for a short period of time. I Also like that cheetahs can be in zoos and also can be trained, petted, and can also (rarely) have babies. Cheetahs need to be saved because they are starting to get really rare and endangered.
