Answer:
b. thick wall.
Explanation:
Endospore is a structure formed by some bacteria, that help them survive unfavourable conditions (e.g. lack of nutrients). This survival strategy of some bacteria (usually Gram+ bacteria) help them stay dormant for a while, until stressful conditions stop. A thick wall composed of many layers (exosporium, spore coat, spore cortex, core wall) of the endospore is what provides resistance to different stressful chemical and physical factors such as UV radiation, temperature, chemical damage etc.

Pretty sure it’s heterotrophic eukaryote
Yes, It seems that evolution has occurred in this area.
Explanation:
Evolution refers to a phenomena in which new traits or alleles that favor a better survival of organisms in a given environment, become fixed in the population.
Evolution is characterized by appearance of new characters and change in allele frequencies.
In the given situation we find that the frequency of the recessive allele in the population has changed over time and the percentage has become fixed.
So, we can say that evolution has occurred in the robin population
I don't know the answer options, but it would probably either be phase of matter or physical change.
