The vascular system of the plants are responsible for transporting water and needed nutrients for the plant to survive. Hence, when this is disturb certain transpirational pull is also disrupted, rendering the plant unable to collect water effectively. Thank you for your question.

Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
They would die or have to have food digested for them.
Answer:
The compound is dissolved in water
Explanation:
"aq." is the abbreviation for "aqueous" ( watery).
In chemical equations the symbol (aq) means that the substance is dissolved in water.
