N the early 1900's a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac

t that DNA could not be found outside the nucleus led scientists to belive that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiement that ultimately identified the site of protein synthesis. They also identified the molecule respnsible for transporting information from the nucleus to the site of protein synthesis. What was this newly identified molecule?
Your answer:
How does the cytoplasm synthesize protein?
How does DNA replicate in the cytoplasm to make genes?
What molecule transports information from the nucleus to the cytoplasm to make protein?

The plasma membrane or the cell membrane is the one that protects the cytoplasm of a cell. It is mostly composed of lipids and proteins. It has a phospholipid bilayer that controls the entering and exiting of molecules in the cell and at the same time, provides protection for the cell or plasma membrane. It has polar head and a nonpolar tail. Proteins embedded within the phospholipid bilayer have the same function of the plasma membrane that includes selective transport. The phospholipid bilayer consists mainly of the lipid molecules.

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC  -->1/16  

RRCc,  RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

-why is respiration important for a cell?
Grace [21]
Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.

Tid-bit of info:
Cellular Respiration Formula:
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula: 
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆
