35m/s is meters per second.
35x35=1225
it will have gone a total of 1225 meters on thirty five seconds
1. If the red blood cells are placed in beaker B, water would move out of the cells by osmosis and cause the cells to shrink. this is because the the solution is hyper tonic compared to the red blood cell.
2. If some red blood cells are placed in beaker A,
Water would move into the cells by osmosis and the cells would swell.
3. The concentration of water inside and outside the cells will be equal so no osmosis would occur. There is no osmotic pressure.
4. Water takes part in the production of lipids and carbohydrates.
5. The membrane and water are both involved in the movement of materials into and out of the cell. The membrane is semipermeable therefore it allows the transmission of materials into and out of the cell. water acts as a solvent for the materials entering the cell as in their original forms, they can not enter through the cell membrane pores.

7. OSMOSIS AND DIFFUSION are both examples of passive transport as the cells do not take part in the transport. It only occurs due to uncontrollable conditions that occur in a cycle in the cell.
Answer:
The velocity of the blood in the thinner arteries is 0.1 times that of the thicker artery.
Explanation:
To find the velocity of the blood we need to use the continuity equation:
(1)
<u>Where</u>:
n: is the number of branches
A: is the cross-sectional area
v: is the velocity
For artery 1, we have:
n₁ = 1, A₁ = 1 cm², v₁ = v
For the 20 arteries (2), we have:
n₂ = 20, A₂ = 0.5 cm², v₂ =?
By using equation (1):
Therefore, the velocity of the blood in the thinner arteries is 0.1 times that of the thicker artery.
I hope it helps you!
<span>Answer: capillary oncotic pressure.
In the vascular system, there is the hydrostatic pressure that caused by the heart pumping the blood and oncotic pressure that caused mostly by protein. This pressure keeps the water inside the blood vessel and a change can cause some disease.
Low protein in the blood can cause edema which was the water inside blood vessel come out to interstitial tissue because the oncotic pressure is dropped.</span>
The frictional force is given by
where m is the mass of the puck,
and
is the dynamic coefficient of friction.
The work done by this force to stop the puck is
where
is the total displacement of the puck.
The initial kinetic energy of the puck is
with v being the puck initial velocity. The puck comes to rest after 12 m, this means it loses all its kinetic energy, and for the principle of conservation of energy this loss of energy is equal to the work done by the frictional force. So we can write
and from this we can find the inizial velocity of the puck:
