<h3>Answer</h3>
B)
FN - mgcosФ = 0
<h3>Explanation</h3>
Given the mass of an object, forces that will be acting on it are as following
- Force due to gravity (weight) of an object
- The Normal force (the perpendicular force from that the inclined surface exerts on the object)
- Any frictional forces (due to static friction or kinetic friction, if applicable) along the incline
- The corresponding force component along the incline (downhill force due to gravity)
Force due to gravity = -mgcosΔ
Normal force = fN
Frictional force = -f
force applied forward = mgsinΔ
Horizontal force = mgsinΔ - f
vertical force = fN - mgcosΔ
Answer:
C. both

Answer:
Facilitated diffusion of solutes occurs through protein pores in the membrane.
Explanation:
Facilitated diffusion: It is known as a type a passive transport which diffuses the solutes through specific trans membrane integral proteins in the plasma membrane. Transport proteins helps in diffuse some ions, and molecules across the plasma membrane.
There are three types of transport proteins which are involved in this diffusion:
1) gated channel proteins.
2) carrier proteins.
3) channel proteins.
Some example of facilitated diffusion are: glucose transporter, ion channels, and aquaporins.
