Answer:
semipermeable
Explanation:
semipermeable membrane, such as plasma membrane, only allows only some materials such as oxygen—small material. other <em>stuff</em><em> </em>like starch couldn't get in.
Velocity change increases as the force increases.
Even though this question is incomplete, but we can approach it from the stand point of Newton's second law of motion.
According to this law, force is directly proportional to change in velocity.
F = m(v - u)/t
F = force applied
m = mass of the body
v = final velocity of the body
u = initial velocity of the body
t = time taken
This means that velocity change increases as force increases.
Can you give more details? do you have a screenshot you can send?
The answer is "Every cell has a nucleus that contains genetic material."
So to solve this problem, we are going to have to set up a couple unit conversions and then cancel units:

This method can be used to convert between many different units and is a very helpful tool for questions such as these.
