There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.
Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.
The distance between the two points is always positive because the direction does not matter.
However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.
In other words:
<em>Speed </em>is looking at the <em>magnitude</em>
<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>

Only euryhaline organisms would.

Answer:
plasma, red blood cells, white blood cells, and platelets
Explanation:
PLASMA: The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it.
RBC: The main job of red blood cells, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs.
WHITE BLOOD CELLS:They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health.
PLATELETS: a component of blood whose function is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot.
hope this helped you

I think the answer is C but i am sorry if i am wrong i took this test but i am pretty sure it is C have a good day and good luck on the test
Answer:
The plasma membrane is made up by a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. Only relatively small, non- polar materials can easily move through the lipid bilayer of the plasma membrane.
