Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

De acuerdo a lo visto en clases, de los siguientes elementos señale 3 que no pueden estar ausentes en una célula.

Rama09 [41]

Answer:

The nucleus, cell membrane and cytoplasm.

Explanation:

The nucleus, cell membrane and cytoplasm are three elements that cannot be absent in a cell because they are necessary for the survival of the cell. The nucleus controls and regulates the activities happening inside the cell e.g. growth and metabolism etc. Cell membrane acts as a wall to protect the inner part of the cell from the external environment as well as allows nutrients and gases inside and outside the cell. Cytoplasm serves as a medium for the conduction of nutrients and waste from on place to another and also for the medium for organelles in which they floats.

When most proteins, fats, and carbohydrates are digested completely, they are converted to end products that?

nadezda [96]

The choices can be found elsewhere and as follows:

1.are soluble and can easily pass through cell membranes
2.contain long chains of amino acids and fatty acids 
3.contain atoms of carbon, hydrogen, oxygen and nitrogen 
4.are a direct result of dehydration synthesis

I believe the correct answer is option 1. When most proteins, fats, and carbohydrates are digested completely, they are converted to end products that are soluble and can easily pass through cell membranes. So as to distribute the nutrients needed in different parts of the body.
