Which of the following statements is FALSE?
Delvig [45]

Answer:

c. Damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions.

Explanation:

The primary motor cortex is an area in the brain that is responsible for the control and regulation of activities that involves movement of the body as well as the postures they body takes which we also refer to as motor skills.

The primary motor cortex sends signals in the form of nerve impulses to the brain and this in turn helps in the maintenance of the motor skills that is carried out by the body.

Not only does the damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions, it also causes other losses such as constant contraction of the muscles also know as spasticity, involuntary muscle contraction also referred to as clonus.

Water molecules diffuse through the cell membrane through aquaporins. How are these proteins helpful in osmosis?
romanna [79]

Answer:

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
