Answer:
If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.
Explanation:
When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.
A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.
Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
- <em>Adenine 30%.
</em>
- <em>Thymine 30%.
</em>
- <em>Cytosine 20%.
</em>
- <em>Guanine 20%.
</em>
- <em>Total ..... 100%
</em>
In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
Answer:
The mass of an object is a measure of the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. Mass does not change with gravity as weight does due to the act of pulling down on an object making it in fact heavier.

Answer:
The correct words are - platelets, increased, tissue, thromboembolism, hemophilia, and bleeding.
Explanation:
Thrombocytopenia is a condition in which the number of platelets decreases significantly in the blood due to less production from the bone marrow or higher or increased breaking down of the platelets.
If the flow of the blood stops completely in between the heart and muscles and can lead to stroke in an individual if thromboembolism is not treated. Hemophilia is a blood condition that is a genetic disorder and inherits from the parents. In which blood does not clots and slightest bumps can lead to bleeding.
You might not have enough oxygen you have to survive
Answer:
C. Oxygen
Explanation:
Most, if not all living things use oxygen in some shape or form. While Helium is the most abundant element, it is asking for living things, in which oxygen is a vital building block in maintaining life. Without oxygen, most animal species and humans would die.
