A is the correct answer, eukaryotic cells have membrane-bound nucleus, prokaryotic cells do not.
Oxidative Phosphorylation is the metabolic process needed
to provide energy for the cell. It is the final stage in the process of
cellular respiration, where acetyl CoA produce energy precursors that leads to the
phosphorylation of ADP, producing adenosine triphosphate (ATP) and in return
provide energy. Moreover, when the body lacks oxygen, fermentation happens.
During glycolysis, only two ATP molecules are produce and the pyruvate is
reduce to NADH forming lactate. Meanwhile, in alcoholic fermentation pyruvate
is converted to ethanol, releasing CO2. Lastly, the co-enzyme that is involved
in photosynthesis is NADP+ where extra phosphate group is attached.

I believe the answer is D, as we can reproduce and we have to be the same biological species to do that
Weathering is process in which the rock breaks down into due to physical and chemical processes. It leads to wearing and tearing in the rocks. Weathering can be of three types physical weathering, chemical weathering and biological weathering.
Thermal stress weathering or insolation weathering occurs in places where there is a large change in daily temperatures. It causes the peeling off of the outer layer of the rocks.
