Answer:
When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.
Explanation:
If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.
The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.

The trait distribution most likely change over this time such that the plants with favorable traits, medium-tip leaves and drip-tip leaves will survive due to natural selection.
<h3>What is natural selection?</h3>
Natural selection is the process by which organisms which are better suited to their environment survive whereas those not suited die off.
The organisms that are suited to their environment possess special features which enable them to adapt to changes in their environment.
Considering the plants in the rainforest with different leaf tips:
- Trait A: medium-tip leaves
- Trait B: drip-tip leaves
- Trait C: wide-tip leaves
Since fungi grow in moist environments, it can be seen that plants with Trait C will be least favored to survive, while plants with Trait B will be most favored to survive by natural selection.
Thus;
- In year 1: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves.
- In year 5: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 0 % have drip-tip leaves
- In year 10: the composition of plants is 25% have medium-tip leaves, 75% have wide-tip leaves, and 0% have drip-tip leaves.
In conclusion, plants with favorable traits will survive due to natural selection.
