Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

Answer:
In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape. The sugar-phosphate backbone is negatively charged and hydrophilic, which allows the DNA backbone to form bonds with water.
Are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group, and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue. ... They can form lipid bilayers because of their amphiphilic characteristic.
<span>The correct answer is A. water. That's because water's chemical composition is such that it can't be decomposed and turned into a fuel. Unlike Corn, sugar cane, and wood, it can't be used to power machines. The other ones are organic and can be used as biofuel, while wood can even be used in the form of coal as coal is nothing else than wood.I hope that my answer is helpful! Let me know if you need something more :)</span>
