The part of the bacteria cells that helps them stick to the surface of objects or beings is called the <span>pilus, and the pilus is found all over the surface of the bacteria.</span>
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:

You've communicated and talked!
Explanation:
<em>I HOPE THIS HELPED!!</em>
The cell has to use active transport when it's trying to transport material against the concentration gradient. (from low to high concentration) Or, if a molecule is too big to diffuse through the cell membrane, it must be moved through using a carrier protein.
Hope that helped you.
<span>The use of steam
is essential in most power plants. Water is heated and dispatched through a
turbine creating thermal energy. Later on, it is converted to electricity. The
steam enables the turbines to rotate which activates a generator, producing
electricity. </span>
