Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?
1 answer:
Answer:
<u>The Golgi apparatus </u>plays a central role in molecular transport after biosynthesis.
Explanation:
Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be <em><u>folded and modified</u></em>. In the Golgi, they are <em><u>tagged and separated</u></em> into lysosomes for export<em> </em><em><u>outside the cell.</u></em>
The Golgi system comprises of several regions known as cisternae; they act as<em><u> independent microenvironments</u></em> where products requiring their own unique conditions are <em><u>converted into new, stable biomolecules</u></em>.

Answer: The probability is 100%.
Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:
- If it is a boy, he inherites the chromosome Y from his father and X from his mother;
- If it a girl, she inherites X from her father and X from her mother;
In the question, the woman is color-blind, which means she carries the recessive alleles:
The man, on the other hand, is normal, so his X-linked genotype will be: .
Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one from her mother and one
from her father.
So, the daughter's genotype can only be heterozygotic in other words, the probability is 100%.
