Answer:
a. This is actually a case of frequency-dependent selection. With too many cheaters in a population, the fruiting body's stalk is not built well, and all individuals have lower fitness.
Explanation:
Frequency dependent selection is a process in evolution whereby the
a gene, genotype or phenotype varies depend on the percentage of that gene, genotype or phenotype that is present in the population.
There are two types of frequency dependent selection:
a. Positive frequency dependent selection.
b. Negative frequency dependent selection.

Answer:
The correct answer is option d. "Elastic channels".
Explanation:
The vascular plants uses xylem and phloem cells that carry water and nutrients to all the parts of the plant, which are present in the leaves of the plant. Stomata is part of the vascular system of a plant, but it serves for gas exchange instead of water and nutrients exchange. Palisade mesophyll is a structural component that contains columnar cells with spaces between them, located in the leaves of vascular plants as well. A component that is not part of the vascular plant leaf anatomy are the elastic channels.
