6 0

Answer: D) a hollow soccer ball

Explanation:

Carbon is capable of forming many structurally different forms of the same element due to its valency. These forms are called allotropes. One of these is the buckminsterfullerene. It has a cage-like fused-ring structure made of twenty hexagons and twelve pentagons. If you look at this structure, it resembles a soccer ball.

Cells in the pancreas are responsible for producing insulin, a protein excreted from the cell and used to help regulate blood su
GarryVolchara [31]
The choices for the above question are:
<span>
A. The ribosomes lining the cell membrane will make it so it can be sent out of the cell more quickly.

B.The ribosomes surrounding the Golgi apparatus will make it so it can be more easily captured and wrapped in membrane.

C.The ribosomes on the endoplasmic reticulum will make it so it can be wrapped in membrane and sent to the Golgi apparatus.

D.The ribosomes floating in the cytoplasm will make it so it can be bent into the correct shape.
</span>
The right answer is C. Ribosomes are more or less located in two general areas - freely in the cytosol or attached to the rough endoplasmic reticulum. Now, you know that these proteins will be secreted. Keep in mind then, that ribosomes associated with the ER create their proteins in the lumen or interior of the ER. The ER then packages these proteins into vesicles and secretes them to the Golgi, which secretes them to the membrane. So, ER-associated ribosomes are bound by vesicles, and free ribosomes in the cytosol create proteins are not. I hope that this is the answer that you were looking for and it has helped you.

olya-2409 [2.1K]

Answer;

-PET scan

A PET scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x-ray

Explanation;

-A positron emission tomography (PET) scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

-A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.

-In a PET scan, a machine detects radiation that is emitted by a radiotracer. A radiotracer consists of radioactive material that is tagged to a natural chemical, such as glucose.
