When tissues are injured or infected, chemical signals can be releases that affect the plasma membrane of cells that line the nearby blood vessels. These blood vessels cells (endothelial cells) respond to the chemical signals by displaying a type of glycoproteins on their surface. These proteins will attach to circulating white blood cells bringing them to the site of injury or infection. These glycoproteins would best be described as ________.
Answer:
Cell Adhesion Molecules (CAMs)
Explanation:
took the test
These proteins will bind to moving white blood cells, transporting them to the location of the infection or damage. These glycoproteins would best be described as cell adhesion molecules.
What are cell adhesion molecules (CAMs)?Chemical signals that alter the plasma membrane of the cells that line the adjacent blood arteries may be released when tissues are wounded or diseased. These blood vessel cells (endothelial cells) respond to the chemical signals by outwardly exhibiting a particular class of glycoproteins.
The sort of protein molecules known as cell adhesion molecules may be found on the surface of cells and are involved in the process of cell attachment.
The intracellular, extracellular, and transmembrane domains of molecules make up single-pass transmembrane receptors.
Therefore, these glycoproteins would best be described as cell adhesion molecules.

Convection currents cause changes in the earths crust. Describe what would happen in each situation.
•Plates move apart:
•One plate goes under another:
•Plates move together:
Answer:
Hope this helps!
Explanation:
1. At divergent boundaries, plates move apart from each other. When this happens, new plate material forms.
2. Two plates pushed together create a convergent fault.
3. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down.
Following things would occur:
1. New plate material forms as a result.
2. A convergent fault is created when two plates are forced together.
3. The margin of the oceanic plate will be pushed downward if one plate is continental and the other is oceanic.
What are convection currents?The transfer of energy from one location to another is what's known as a convection current, and it may be thought of as a process. This type of heat transfer is also known as convective heat transfer.
Convection currents in the earth's mantle have been hypothesized to be related to the movement of tectonic plates. This hypothesis has been developed by geologists. The process of rising, spreading, and sinking of gas, liquid, or molten material that is caused by the application of heat is referred to as convection currents.
