Ribosomes can be found on the surface of the endoplasmic reticulum and suspended in the cytoplasm.

Biology
1 answer:
Alisiya [41]3 years ago

True.

Ribosomes are organelles inside a cell made up of protein and ribosomal RNA (rRNA).

Ribosomes synthesize proteins by linking amino acids together. Some ribosomes float freely in the cytosol of a cell, while others bind to the endoplasmic reticulum.

Free ribosomes are those found floating freely in the cell cytosol. They mainly manufacture proteins needed for the cell's own use.

Bound ribosomes are found "bound" to the endoplasmic reticulum creating what is known as rough endoplasmic reticulum. Most of the proteins made by these bound ribosomes are transported outside the cell for use in other parts of the body.

Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
laiz [17]

Answer:

A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).

Explanation:

Susan is right in this case because her <u>son with type B blood may have a mother with type B blood and a father with type O blood</u>.

Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.

In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.

Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:

<em>Alleles      O     O </em>

<em>B            B/O  B/O </em>

<em>B            B/O  B/O</em>

So it is very likely that the child is Craig's son and Susan is right.

Why is it so difficult to breathe when snorkeling at a depth of 1?
Mamont248 [21]
Because your lungs get inflated like a balloon they become compressed when submerged in water and the air within is compressed. Air will not itself flow from one region of low pressure into a region of higher pressure. The diaphragm in one's body reduces lung pressure to permit breathing, but limit is strained when nearly 1m below the water surface. It is exceeded at more than 1,m.
