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.
Temperature increases as depth increases.
Answer:
No, it cannot. The car needs the friction of the surface to drive because the car pushes the surface backwards, and the surfaces makes a reaction force pushing the car forward, and that works because of the friction. In a frictionless surface the tires would rotate in the same place
Answer:
Explanation:
mass of object, m = 3 kg
spring constant, K = 750 n/m
compression, x = 8 cm = 0.08 m
angle of gun, θ = 30°
(a) As the ball is launched, it has some velocity due to the compression in the spring, so it has some kinetic energy.
(b) Let v be th evelocity of ball at the tim eof launch.
by using the conservation of energy
1/2 Kx² = 1/2 mv²
750 x 0.08 x 0.08 = 3 x v²
v = 1.265 m/s
By use of the formula of maximum height
h = 0.02 m
h = 2 cm
I am thinking that maybe the problem is not with the calibration. It might be that the buffered solution is already expired since at this point the solution is already not stable and will give a different pH reading than what is expected.
