1. Protein Channel pumps ions and other substance through the cell membrane
2. Hydrophilic - Packed love water
3. Hyphobic - Hate water
4. Phospolipid bilayer - the cell membrane
Explanation:
One type of molecule (or a few molecules that are closely related) is all that a channel will accept for transit.
What role of channel protein and membrane component?A channel protein is an illustration of a transport protein; it serves as a pore in the membrane to permit water molecules or small ions to move through quickly.
Water may quickly diffuse through the membrane thanks to aquaporins, which are proteins that function as water channels. Ion channel proteins enable unrestricted ion transport across the membrane.
Channel proteins span the membrane, forming hydrophilic tunnels that let their target molecules diffusely pass through.
For instance, channel proteins enable the passage of bigger molecules like glucose as well as ions like sodium, potassium, and calcium through the membrane.
Therefore, Large or charged molecules can pass across the membrane to channel proteins.

The diagram below shows the relative concentration of molecules inside and outside of a cell. Which statement best describes the general direction of diffusion across the membrane of this cell?
(1) Glucose would diffuse into the cell.
(2) Protein would diffuse out of the cell.
(3) Carbon dioxide would diffuse out of the cell.
(4) Oxygen would diffuse into the cell.
HELP PLEASE
Carbon dioxide will diffuse out of the cell in the given picture. Option C is correct.
Diffusion:
It is the phenomenon in which a substance moves from its higher concentration to its low solute concentration.
Here,
The concentration of Carbon dioxide is higher inside, hence it will move towards the outside due to diffusion.
On the other side, the statements are showing oxygen, proteins, and glucose are moving against the concentration gradient.
Therefore, Carbon dioxide will diffuse out of the cell in the given picture. Option C is correct.

what is the term that is used to describe short-lived, local changes in the membrane potential in a neuron?
Graded potential is the term which is used top describe local changes which
are short-lived.
Graded potential are temporary changes that occurs in the membrane
voltage as a result of differences experienced in stimuli
Graded potential experiences a decrease with as more distance is covered
in the membrane and the magnitude has a direct relationship with the
strength of the signal/stimuli. They help to increase the functions of the
neurons and nervous system as a whole.

acceleration?
a. 40 m/s2
b. 20 m/s2

C. 10 m/s2
d. 2 m/s2
5. Which units can be used to express force?
a. N
b. kg/s2
c. kg. m/s2
d. two of the above
6. If you know the mass of an object, you can calculate its weight with the formula
a. F=mx9.8 m
b. F=mx9.8 m/s
C. F=mx9.8m/s2
d. F=mx0.98 m/s2
Answer:
4. 2 m/s²
5. Two of the above (both N and kg.m/s² are equivalent)
6. F = m×9.8m/s²
Explanation:
4.
Force = mass × acceleration
40 = 20 × a
a = 40/20
a = 2
5.
Force (in N) = mass (in kg) × acceleration (m/s²)
so the units are equivalent:
N = kg.m/s²
6.
Force = mass × gravity
This is an adaptation of:
Force = mass × acceleration
Gravity is an acceleration of 9.8m/s²
