Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- <u>Claim</u>: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- <u>Evidence</u>: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- <u>Reasoning</u>: <u>cohesion</u> in water depends on the force of attraction between H₂O molecules, <u>adhesion</u> is the capacity of H₂O molecules to join other different molecules and —together with <u>surface tension</u>— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.
"Apical Meristem Tissue" is the part of the plant among the following choices given in the question where the activity in the plant stem could have caused this. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has come to your help.
Answer:
I think the answer is the first option, more reliable and harder to use.
Explanation:
I think this because technology is expensive and the most reliable thing we have right now so the other options don't make sense.
It is found in the understory or the lower canopy
Answer:
Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.
Explanation:
undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.
Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.
Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.
