Distinguish between smooth endoplasmic reticulum and rough endoplasmic
reticulum (1 point)
Smooth endoplasmic reticulum has ribosomes attached to
its surface
Smooth endoplasmic reticulum has vacuoles attached to its
surface
Rough endoplasmic reticulum has ribosomes attached to its
surface
Rough endoplasmic reticulum has vacuoles attached to its
surface

Answers

The smooth endoplasmic reticulum is different from rough endoplasmic reticulum as the rough endoplasmic reticulum has ribosomes attached to its surface which are absent in smooth endoplasmic reticulum. Thus, the correct option is C.

What is Endoplasmic reticulum?

Endoplasmic reticulum (ER) is a large, dynamic structure which serves for many roles in the cell. There are two types of ER which are Smooth Endoplasmic Reticulum (SER) and Rough Endoplasmic Reticulum (RER). The diverse functions of the ER are performed by distinct domains present in the ER consisting of tubules, sheets and the nuclear envelope.

Rough endoplasmic reticulum contains ribosomes on its surface and synthesizes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of SER are found in the cells which participate in lipid metabolism and detoxification of the body, such as liver cells.

Therefore, the correct option is C.

what does unequal division ensure?

Answers

Answer: unequal divisions by design provides a unique synthetic system capable of making decisions on its future fates and states by selectively utilizing two types of divisions.

Explanation:

Stem cells make decisions on either self-reproduction or differentiation by selectively utilizing equal vs. unequal cell divisions Stem cells reproduce themselves by equal divisions. However, they undergo a one-round of an unequal division to reproduce one daughter stem cell which is identical to the original and to produce the other daughter cell that is destined to differentiate to a specialized cell type, thus differentiating into non-stem cell lineages – the process known as “asymmetric cell division”. The differentiated cells reproduce themselves via equal divisions. Therefore, the ability to control equal vs. unequal divisions by design provides a unique synthetic system capable of making decisions on its future fates and states by selectively utilizing two types of divisions.

Over the last two decades, several synthetic cell division systems were synthesized However, none provided a system where equal vs. unequal divisions could be controlled by design. Hence, we set out to synthesize an artificial cell system where we can control equal vs. unequal divisions by design.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism

Answers

Answer:

The child has a 1/4 chance of having albinism

Explanation:

I hope this helps!

For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.

What is the probability that their first child will have albinism?

This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.

Do both parents have to carry the albinism gene?

Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.
