Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."
I hope this helps a little bit.
The answer is A, true.
Fungal cells have cell walls which are made out of chitin, unlike plant cells, their cell walls are made up of cellulose.
Other reasons that why fungi are not classified as plants include that because they have no chloroplast, instead they feed on dead organic matters. Another reason is that they store carbohydrates in form of glycogen, instead of plants which store carbohydrates as starch instead.
