Answer;
D. Meiosis ii of mother
Explanation;
-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.
-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
My answer may not be precise, but I believe if you changed your question to "The presence of these structures indicates that the student is looking at a cell of what organism", then I would safely say a plant, because plants, unlike animals, have cell walls in addition to cell membranes. :) Hope this helps!

Answer:
As amoeba is a unicellular organism all the physiological processes are performed by the single cell.
Explanation:
The food is captured by the pseudopodia and after entering into the body it forms food vacuole. Then the food is broken down by enzymatic activities within the food vacuole and the simplified food absorbed by the cytoplasm.
The remaining undigested food is expelled by the plasma membrane. This is done by rupture of the cell membrane and the waste products diffused out of the plasma.
Most of the time the food captured by amoeba is absorbed more and less waste is formed.
Amoeba reproduces the process of binary fission. It is a type of asexual reproduction where the body is divided into 2, 4, 8.... then 16 and so on.. many cells. These small amoeboid cells grow and become new organisms.
As it is a single-cell organism, nutrition, assimilation, excretion, the reproduction process occurs at a fast rate.
