Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.

Answer:100% breaths or 50% 2
Explanation:
This means that they each have there own part in the cell, think baseball team. there are different players but you work together
Answer:
<h2>D) 610:190, round seeds:wrinkled seeds</h2>
Explanation:
Let round seed as R and wrinkled seed as r.
So the round is dominant (R) over wrinkled(r).
Hence , round is dominant and wrinkled is recessive rr.
Now cross between pure round (RR) and pure wrinkled (rr).
RR× rr
F1 offspring are: Rr ( all)
Now cross between F1 offspring;
Rr × Rr
F2 are= RR, Rr, Rr and rr
RR and Rr = round
rr= wrinkled.
round to wrinkle ratio is= 3:1
So, 610:190; round seeds:wrinkled seeds is the expected result in the F2 progeny.
