Which cell structure plays a direct role in the release of chemicals from the cell?

Biology
1 answer:
jonny [76]2 years ago
6 0

Answer:

The correct answer is - the cell membrane.

Explanation:

When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.

Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.

A woman who is a carrier for colour blindness (X-linked recessive) has children with a man who has normal colour vision. A. What
viva [34]

Answer:

Explanation:

The Genotype of the  woman is XCbXN

The man XNY

Since the allele for the color blindness is carried on one of the X -chromosomes of the  carrier mother, then  the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal  allele from the  mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal  X allele from the father.

Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes

1. XNY vs XCbXN.Then the one of the  boys will be colorblind  and the one of  girls will be carriers. XNXCb, XNXN, XCbY,XNY  50 %

2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle

Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).

The proportions that will be  the females  since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls  take the defective allele from the mothers and take normal from the father,they will all  be carriers,since the X of the father is normal.

They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.
