Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs. ... Diagram of a plant cell with components labeled.
Less prey for their predators to feed on which would lead to the predators getting endangered in that ecosystem.
Answer:
The answer is B, extensive research of an individual organism over many years.
Explanation:
The question is asking, what best describes Darwin's studies that led to the theory of evolution, it would be a lot of research over a long period of time. Think, if you were to do a school project, would you get your best results over a short or long period of time with little or a lot of evidence/research? So, B is the best answer, I believe.

Answer:
It lacks a cytochrome oxidase for passing electrons to oxygen.
Explanation:
During aerobic respiration, the NADH and FADH2 formed during glycolysis and Kreb's cycle are oxidized through the electron transport chain. NADH and FADH2 pass their electrons to the molecular oxygen via four complexes electron transport chain. Cytochrome oxidase is also called a complex IV of the electron transport chain. It serves to carry the electrons from cytochrome c to molecular oxygen, reducing it to H2O.
In the absence of cytochrome oxidase, electrons from NADH and FADH2 will not be passed to the molecular oxygen. Oxidation of NADH and FADH2 is required to continue glycolysis and Kreb's cycle. Therefore, in the absence of cytochrome oxidase, the cells will perform anaerobic respiration to oxidize NADH into NAD+ so that glycolysis can be continued as a source of energy.
