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.

Mia enjoys studying fossils. She learned how fossils called index fossils are found in the rock layers. The index fossils help scientists study rock ages. In what way do index fossils help determine rock ages?
A. Index fossils are widely distributed but were not around long, and so they show up in only a few rock layers.
B. Index fossils are widely distributed and were around for a long time, and so they show up in many rock layers.
C. Index fossils were around only a short time but they show up in many rock layers.
D. Index fossils are widely distributed and are always found in every sedimentary rock layer.

How it’s possible to compress a given amount of air into a smaller space?
Answer:
The answer will be
Compressed air is made of the same air you breathe in and out, but that air is compressed into a smaller size and kept under pressure. When you take atmospheric air and then physically force it into a smaller volume, the molecules take up less space and the air is compressed.

How could changing to a plant-based diet help reduce world hunger?
IF YOU DONT USE GOO_GLE I WOULD GIVE YOU BRAINLIEST
but if you do then you will see
Answer:
Raising animals for food requires massive amounts of land, food, water, and energy, causes animal suffering, world hunger and disease. Fifty one percent or more of global greenhouse-gas emissions are caused by animal agriculture. It takes almost 20 times less land to feed someone on a plant-based diet than it does on a meat-based diet, since the crops are consumed directly instead of being used to feed animals. Even though there are enough plant-based foods grown to feed the entire world, the majority of crops (including those grown in countries where people are starving) are fed to livestock for the western nations instead of feeding their own people. Eating a plant-based diet will help starving people around the world, the environment, your health and the animals!
Explanation:
ok so, as you asked the question you are saying how we change to a plant based siet help to reduce the world's hunger

Evaporation happens in the Dead Sea and other bodies of salt water (like the oceans) as part of the water cycle. What fuels evaporation in bodies of salt water?
Answer:
Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation. A state of saturation exists when these two process rates are equal, at which point the relative humidity of the air is 100 percent. Condensation, the opposite of evaporation, occurs when saturated air is cooled below the dew point (the temperature to which air must be cooled at constant pressure for it to become fully saturated with water), such as on the outside of a glass of ice water. In fact, the process of evaporation removes heat from the environment, which is why water evaporating from your skin cools you.
Explanation:
Solar energy fuels evaporation in bodies of salt water. Evaporation happens in the Dead Sea and other bodies of salt water (like the oceans) as part of the water cycle.
What is evaporation?Evaporation in bodies of salt water is fueled by solar energy from the sun. The sun's heat causes the water molecules in the surface of the salt water to gain energy and become more active. As the water molecules become more active, they gain enough energy to break free from the liquid and become water vapor, which rises into the atmosphere. This process is known as evaporation.
In bodies of salt water, the process of evaporation leaves behind salt and other minerals, which increases the salinity of the water. The high salinity of the Dead Sea and other saltwater bodies can also affect the evaporation rate, as the presence of salt can make it more difficult for water molecules to escape from the surface.

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.

Identify a situation in which friction works against you.
Answer:
Friction tends to oppose any relative motion between objects, acting at the surfaces in contact. If there is relative motion, the frictional force is the kinetic force of friction. If there is no relative motion, the frictional force is the static force of friction.
