<span>Atmosphere is the system that includes oxygen, nitrogen, and ozone. The correct answer is C.

The glucose transporter used by cells to obtain glucose from the media is a protein embedded in the membrane. When researchers f
jeka57 [31]

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

When transporting donated platelet units, what is the maximum amount of time that agitation of platelets can be stopped for
SIZIF [17.4K]

24 hours is the maximum amount of time that agitation of platelets can be stopped.

<h3>What are platelets?</h3>

Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They aid in the formation of blood clots that help wounds heal and to slow or stop bleeding. It can be problematic to have platelets that are too many, too few, or aren't functioning properly.

Platelets' main job is to stop and prevent bleeding. The body sends signals to platelets that direct them to the affected location when a blood artery is damaged. Adults typically have between 150,000 and 450,000 platelets per microliter of blood, which is considered normal. Less than 150,000 platelets per microliter indicate a low platelet count. People with thrombocytopenia have low platelet levels. We can bleed heavily and bruise easily if our platelet counts are low.

Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
KiRa [710]

Answer:

corrugated cardboard tube - digestive tract

irregular surfaces on the corrugated tube - villi

pump - heart

Plastic tubing - blood vessels

Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
