Answer: It is an observation which cannot be explained.
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.
Answer:
Decelerating
Explanation:
One arrow is moving it forward but the other arrow is using more force to move it backwards causing it to have a reduction in speed.
Correct answer choice is:
C. Medium range
Explanation:
Medium range exercises are used to gain extra strength and fitness. Usually, heavyweights are used with less number of repetitions. These sort of exercises are mostly the hardest t do. All you need is to have a high level of motivation and stamina, which can be gained by running or cycling.
Answer:
T = 1.766(M-m) Nm where M and m are the 2 masses of the objects
Explanation:
Let m and M be the masses of the 2 objects and M > m so the system would produce torque and rotational motion on the pulley. Force of gravity that exert on each of the mass are mg and Mg. Since Mg > mg, the net force on the system is Mg - mg or g(M - m) toward the heavier mass.
Ignore friction and string mass, and let g = 9.81 m/s2, the net torque on the pulley is the product of net force and arm distance to the pivot point, which is pulley radius r = 0.18 m
T = Fr = g(M - m)0.18 = 0.18*9.81(M - m) = 1.766(M-m) Nm
