The missing answer choices are:

a. hypotonic

b. isotonic

c. osmosis

d. hypertonic

The correct option is d. hypertonic

Explanation:

A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.

Answer: what are the choices

Explanation: hi

When dissolved in water, electrolytes produce solutions of ions. The correct option is 2.

When electrolytes are dissolved in water or other solvents, they produce ion solutions that conduct electricity.

These ions, which can be positively or negatively charged (cations or anions), form when the electrolyte dissociates into its constituent atoms or molecules in the presence of a solvent.

Electrolytes include ions such as sodium, potassium, calcium, magnesium, chloride, bicarbonate, and phosphate.

These electrolytes are important in many physiological processes in the body, including fluid balance, nerve impulse transmission, and muscle function.

Food and drink, supplements, and intravenous fluids are all sources of electrolytes.

Thus, the correct option is 2.

The correct statement is that the outer planets are further from one another than the inner planets. So the correct option is D.

There are eight planets in our solar system that are classified according to their distance from the sun.

The planets closest in distance to the sun are called the inner planets. The first four planets of the solar system are classified as the inner planets. These are Mercury, Venus, Earth, and Mars.

The rest of the four planets of the solar system are farther in distance from the sun. They are called the outer planets. These are Jupiter, Saturn, Uranus, and Neptune.

The outer planets are much bigger than the inner planets and make up for 99 percent of the mass of all celestial bodies that revolve around the sun.

The outer planets are mainly composed of gases and are called gas giants or jovian planets. The distance of outer planets between one another is much more than the distance of inner planets between one another.

Therefore, the correct option is D.
