A,C, D.. Those are correct ..
In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
Answer:
B. The cell cannot be a human
Explanation:
Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.
The correct answer is C) only some survive because variation exists
