Answer:
The answer is A
Explanation:
Because available energy decreases as you go up
Answer:
D. One is polar, and one is nonpolar
Explanation:
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N
Molecules that cannot cross the membrane bind to receptors in the membrane. When the signal binds to a receptor changes it's shape. Other Molecules inside the cell respond to the chainging shape of the receptor.
