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.
Answer:
transcription is the synthesis of an mRNA molecule using a DNA molecule for a template. That mRNA molecule then goes on to complete translation in the ribosome. Translation is the process in which proteins are produced based on instructions carried by mRNA.
Explanation:
the answer is b. energy and matter can enter and leave.
Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
