The diagram below represents a solar eclipse. The area in the full shadow is where a total solar eclipse occurs. Based on the diagram, which statement is correct? A. No people on Earth will see the total solar eclipse occur because the Earth spins on its axis. B. The Moon's shadow is cast on all of Earth, so people in all locations will see the total solar eclipse. C. Only people at certain locations on Earth will see the total solar eclipse as it occurs. D. People in some locations will see a total solar eclipse and a total lunar eclipse at the same time.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
