The various parts of the endomembrane system serve different functions in the cell. In this activity, you will identify the role
Viktor [21]

Answer:

A) Lipid synthesis : Smooth endoplasmic reticulum.

B) Calcium ion storage : Smooth endoplasmic reticulum.

C) Poison detoxification : Smooth endoplasmic reticulum.

D) Protien synthesis : Rough endoplasmic reticulum.

E) Protien modification and sorting : Golgi apparatus

F) Cisternal maturation : Golgi apparatus.

G) Macromolecule digestion : Lysosomes

H) Autophagy : Lysosome.

Explanation:

<u>Smooth endoplasmic reticulum</u> is involved in the synthesis and storage of lipids . It also stores the calcium ions and contain enzymes responsible for the detoxification of the poisonous substances like CCL4 and other agents. SO the answer of A , B  and C is Smooth endoplasmic reticulum.

<u>Rough endoplasmic reticulum</u> contains ribosomes which synthesize protiens thus answer of D is RER.

The <u>Golgi apparatus</u> functions as a factory in which the protiens recieved from the endoplasmic reticulum are modified and sorted and is also involved in cysternal maturation so answer of option E and F is Golgi apparatus.

<u>Lysosomes</u> are the part of endomembrane system involved in the digestion of the macromolecules and in the recycling of the worn-out organelles hence also involved in autophagy. Hence answers of G and H is lysosomes.

Genetics help please!!Two mothers give birth to sons at the same time at a busy urban hospital. The son of mother 1 is afflicted
Alika [10]

Answer:

If mother 1 is a carrier of hemophilia, it is likely that her son would in fact have hemophilia while the son of mother 2 does not. Mother 1 would have the genotype XᴴXʰ, meaning she has one recessive allele for hemophilia, while the father would have the genotype XᴴY, and would neither be afflicted with hemophilia nor carry it. If you do a punnett square, it shows that the son of mother 1 would have a 50% chance of having hemophilia, since he wouldn't have a second X chromosome with a dominant allele to mask the recessive hemophilia allele. Also, if mother 2 has the homozygous dominant genotype XᴴXᴴ despite the father having hemophilia and the genotype XʰY, a punnett square for this couple proves that their son would have a 0% chance of having hemophilia. Therefore, it is very likely that their sons were not switched at birth and the correct answer is D: The fact that the father in couple 2 has hemophilia would not predispose his son to hemophilia. The first couple has no valid claim. Hope this helped!
