Diffusion is the net movement of fluid from area of higher concentration to lower concentration, resulting from the random movement.
From example, if you drop a red ink in a cup of water, the ink will slowly spread among the water, making the water red. This is because the red ink is very concentrated, so it moves to the other part of water to lower the ink concentration. When it reaches the point where whole cup of water is red, it reached equilibrium and there's no more net movement
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below are the choices:
<span>A) lysosomes
B) free cytoplasmic ribosomes
C) roughER
D) plasmodesmata
E) Golgi vesicles

The structure is the site of the synthesis of proteins that may be exported from the cell is roughER
Fast twitch muscle fiber
<span>Fast twitch muscle fiber is known to be most powerful and
lowest in endurance and usually
activated when the body is near maximum exertion. They are identified by a quick
contraction time and usually low resistance to fatigue </span>but are used in powerful bursts of movements like
sprinting. however, muscle fibers have the greatest capacity to produce energy via the anaerobic energy system.
Any type of terrestrial land plant and some aquatic plants too (since you mentioned that it isn't motile)
Answer:
C) 64% AA, 32% Aa, 4% aa
Explanation:
The frequency of dominant allele A is = 80% = 0.8
Since the population is in Hardy-Weinberg equilibrium, p+ q = 1
Here, p= frequency of dominant allele
q = frequency of recessive allele
Given, p= 0.8
So, q = 1-p = 1-0.8= 0.2
Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%
Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%
Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%
