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.

Which organisms are prey?
Herbivores and carnivores are both types of consumers in a food web but they are on different trophic levels. Why are herbivores and carnivores on different trophic leves
оооо
Herbivores have more available energy and are at a lower trophic level because they receive energy directly from producers.
Carnivores have more available energy and are at a lower trophic level because they receive energy directly from producers.
Herbivores have more available energy and are at a higher trophic level because they receive energy directly from carnivores
o Carnivores have more available energy and are at a higher trophic level because they receive energy directly from herbivores,
Herbivores have more available energy and are at a lower trophic level because they receive energy directly from producers in the Food chain. So, the correct option is A.
What is Food chain?A food chain is defined as a linear network of links in a food web that begins with producer organisms and ends at apex predator species, detritivores or decomposer species. It also refers to how organisms are related to each other through the food they eat where each level of the food chain represents a different trophic level.
Producers have 100% of the energy that is derived from the Sun, the next level would receive 10% of it, so herbivores would have a 10% energy level, followed by carnivores at 0.1% and after this another higher trophic level is 0.01%. Herbivores have more available energy and are at a lower trophic level because they obtain energy directly from producers in the food chain.
Therefore, the correct option is A.

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.

Logically why would light move faster in vacuum than in a solid? *
light cannot travel in vacuum; it needs a medium to travel in just like mechanical waves
this is incorrect, light moves faster in a solid
in a solid light gets absorbed by atoms before coming out the other side
there's nothing for light to bounce off of in vacuum
