Diffusion vs. Active Transport: molecules move across cell membranes by two major processes diffusion or active transport. Diffusion is the movement from a high concentration of molecules to a low concentration of molecules. ... Moving molecules with cell energy is called active transport
I believe the answer would be 16:1
This can be looked at by assuming the motor speed is say 2000 RPM. Through the first reduction it is reduced 4 times to 500 RPM. The second reduction of 4:1 reduces it down to 125 RPM. The total reduction is the motor speed of 2000 RPM divided by the final speed of 125 or 16. A gear ratio is the ratio used to determine the angular speed and torque of a geared system.
B .The membrane is what separates, and is the system boundary.<span />
Answer:
Isotonic exercise
Explanation:
Isotonic exercise is basically weight training. It is a type of exercise where you apply force to move a static object. So to move the object, you will need to force your muscles to move them. You can use your own body as weights, use equipment like dumbbells or machines.
Isotonic exercises are good for specific workouts for specific needs. For example runners can do isotonic exercises that focuses on building leg muscles.
