The correct answer is Transfer of RNA.
Transfer of RNA acts as the delivery truck which delivers amino acid to the ribosome for the synthesis of protein and then leaves empty again. Transfer RNA is termed as an adaptor molecule which is composed of RNA which have 76-90 number of nucleotides in length.
It is a link which is between amino acids sequence and mRNA of proteins. The work of tRNA is to specify which sequence from genetic code corresponds to amino acids. mRNA encodes the protein as series of contiguous codons. Its structure can be decomposed into a primary and secondary structure.
<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
</em>
Answer:
145 degrees F
Explanation:
To prevent contamination and food borne infections, raw beef, pork, lamb and veal steaks, chops and roasts must be cooked to a minimum of 145°F internal temperature before being removed from heat source.
This minimum temperature reading will annihilate traces of food borne pathogens in the food and make it safe for consumption.
Answer:
Chemical energy eventually leaves an ecosystem, when the top predator eventually dies. Other plants and animals will use this energy because when the dead body decays, the plants will take some of it through the soil, and put back into the cycle.
