Answer:
The student is most likely viewing a (A) plant cell
Explanation:
All cells have a nucleus, but only green plants contain chloroplasts.
Gradualism and punctuated equilibrium are evolutionary theories. Gradualism suggests a slow, constant pace of evolution, whereas punctuated equilibrium involves rapid speciation events after periods of stability.
The theory of gradualism posits that evolution proceeds gradually, with slow and continuous changes taking place over long periods of time. Species progressively mutate and adapt, leading to gradual phenotypic and genetic changes, eventually resulting in some new species over millions of years.
On the other hand, punctuated equilibrium proposes that species experience long periods of stability (equilibrium), punctuated by short, rapid events of speciation. These dramatic events involve a small segment of the population evolving quickly while the rest of the population remains unchanged, leading to a new species.
In summary, gradualism presents a slow, steady pace of evolution, while punctuated equilibrium supports the theory of sudden evolutionary jumps interspersed with periods of little to no evolutionary change.

Answer:
Pathogenic fungus Ustilago maydis causing a plant disease which is known as corn smut (smuts on maize). This fungus grows in the ears of corn and changes corn kernels into black, and all above parts of the corn.
Corn smut showing a parasitic relationship with corn so, that it is using the corn as a way to spread spores, and causing pathogenic fungus disease.
