Answer:
B. an important international tournament begins in eight months
Explanation:
i just did it on study island
Answer:
For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.
When using liquid reagents, the percent concentration is based upon volume per volume, i.e. #ml/100ml. Example 2: If one wished to make a 70% ethanol solution, 70 ml of 100% ethanol would be dissolved in 30 ml of water (or the equivalent for whatever volume was needed).
<h2>Answer:</h2>
The involved organelles are:
- Nucleus
- Ribosomes
- Golgi apparatus
<h3>Explanation:</h3>
First in nucleus the DNA is transcripted into mRNA which is the transported to cytoplasm.
mRNA is the message containing the information about the sequence of amino acids in proteins.
In cytoplasm mRNA is translated into proteins in the ribosomes.
After making proteins in ribosomes, they are packed into vesicles in Golgi apparatus.
In Golgi apparatus they are directed to their destination whether it is inside the cell or out side the cell.
Answer:
POLYADENYLATION mechanism.
Explanation:
This is the mechanism of adding a poly(A)tail to a mRNA to protect the RNA.This tail is made up of adenosine monophosphate(AMP) compound, and therefore consists of only this purine base stretch.(adenine is purines).
Polyadenylation participate in production of mature mRNA for the process of translation in the cystosol, therefore ensuring stability.
However this tail shortened with time, and in extreme shortness the mRNA is degraded by enzymes in the cells.
Conclusively, the protection provided by the poly(A) tail
and production of mature mRNA ensured the stability of these molecules
