<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein</span>

Answer:
A
Explanation:
There is no much more to say than the letter A describes the process of facilitated diffusion.
The normal diffusion ocurres when the solute passes the membrane through the space of the double layer of phospholipids. Particles that are small and apolar can pass trough the membrane without problems.
For bigger or polar particles we need to use a protein system to help them pass into the cytoplasm. That's what we call Facilitated Difusion.
About the other options:
B) That's the explanation about active transport. That happen for every particle who is going against the gradient of concentration.
C) Again: if we are talking about diffusion, there is no energy needed.
D) The Water Molecules suffer the process os osmotic pressure. Water deslocates to the higher gradient of concentration - contraty what the other particles do.
Cohesion, adhesion and surface tension are different from each other. Adhesion is used in xylem. Surface tension enables an insect to sit on water.
<u>Explanation:</u>
The force of attraction between the molecules of the same type is called cohesion. The force of attraction between the molecules of different type is called adhesion. Tendency of fluid surfaces to shrink to minimum possible area due to the attraction between the liquid molecules is called surface tension.
Adhesion is used in xylem. In xylem water molecules move from the roots to different parts of the plant through the xylem tubes. The adhesive force between the water molecules and xylem walls make the movement of water possible.
Surface tension enables an insect to sit on the surface of a liquid. Due to surface tension the water surface stretches like a membrane due to the higher attractive force between the water molecules.
The inclusions shown near the bottom of the palisades sill are pieces of the triassic sandstone that broke off from the surrounding bedrock during the intrusion. The palisades sill is a fine grained porphyritic ductile sill which forms spectacular cliffs and palisades in the Cimarron River canyon. The majority of the Triassic sandstones found in Worcestershire are from the fluvially deposited Sherwood Sandstone Group which outcrops across the center and north of the county.<span />
Transitional fossils help scientists bridge gaps in the tree of life, resulting in a picture of gradual evolution over millions of years.
