Answer:
<u>Stores DNA</u>
Explanation:
The nucleus controls all the activities of a cell. The chromatin contains the hereditary materials, DNA while the nucleolus is responsible for the manufacture of ribosomes.
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.

Erythrocytes, or red blood cells, transport oxygen to various parts of the body. A low RBC count means that the person will not get enough oxygen to different parts of the body. Therefore, symptoms of anemia include lethargy, feeling of fatigue and dizziness.
Answer:
The correct answer is mechanical energy.
Explanation:
For an internal combustion engine to work you will need to burn fuel. This burning of fuel is called combustion.
It is a chemical process in which mixing oxygen with fuel generates heat for the motor to move
.
The oxygen in this process is called oxidant and together with the fuel it will be the one that manages to run the internal combustion engine.
