Answer: d. none of the other answers
Explanation:
Enzymes that turn chemical energy into mechanical work are molecular motors.
There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin filaments and microtubules carry the motor-driven transport on the cytoskeleton.
The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.
Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.
Hence, the correct option is d.

Answer:
<h2>B) 4, 6, 7, 1, 2, 3, 5</h2>
Explanation:
Action potential ,the change in electrical potential associated with the passage of an impulse along the membrane of exciting cell. The order of steps in generation of action potential is-4.A graded depolarization brings an area of an excitable membrane to threshold.→ 6. in excitable membrane ,after that, Sodium channel get activated,→ 7. aftre that Sodium ions enter the cell and depolarization occurs,→1.after that, then Sodium channels are inactivated,→ 2. Voltage-gated potassium channels open and potassium moves out of the cell, initiating repolarization, →3. Sodium channels regain their normal properties,→ 5A temporary hyperpolarization occurs.
