What hormone helps plants move toward a stimulus?
A.)Ethylene
<u>B.)Auxins</u>
C.)Acids
Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance
Hope It Helps you!

I promise to you I’m not lying the answer is D I just had this question
Structure of Water and Hydrogen Bonding
- living systems depend on water and its polarity as well as hydrogen bonds
- hydrogen bonds result in the cohesion: ability for water molecules to stick together through hydrogen bonds, adhesion: ability for polar part of water to stick to other polar surfaces and surface tension: water's attraction to each other in bonds rather than air so have tension on surface
- cohesion of water is the Attraction between molecules of the same substance.
- Hydrogen bonds between the oxygen of one water molecule and a hydrogen of another water molecule.
- Adhesion of water is the property of water to attract with other substance.

When the body moves the muscles supplies the effort or input force. An effort force is a force that is used to move objects over a distance. It is the force that is used to get work done. The output force is the results of the input force or what one has accomplished. The force that moves the bones comes from the muscles. The energy that the muscles use to produce the force and move it through a distance comes from the food one eats.
