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>.

The answer is D. Animals and plants
Answer:
Transport vesicles will not be brought to either the Golgi apparatus or the plasma membrane.
Explanation:
Microtubules forms part of the structure of the cytoskeleton. It is a polymer of tubulins.
Apart from maintaining the cell structure, cytoskeleton plays a role in transportation in a cell.
A Constructive secretory pathway is an exocytosis process found in all eukaryotic cells, in which transport vesicles destined for the plasma membrane leave the trans-Golgi network in a steady stream
A disruption on microtubules will lead to a change in structure of the cytoplasm. It will not be able to perform its function therefore transport vesicles will not be brought to either the plasma membrane or the golgi apparatus.
<span>Corticotropin-releasing factor is produced by the anterior pituitary, hypothalamus, adrenal glands, and ovaries. It is a hormone released in response to stress. Secretion has been seen to be higher in patients with depression and Alzheimer's disease. In addition to the aforementioned, CRF is secreted in lymphocytes and the placenta.</span>
