PLEASE HELP ME! HELP, PLEASE! 30 POINTS< POSSIBLY BRAINLIEST! when water molecules stack up, creating bonds between different molecules of water, the following explains the chemical bonds occurring:
(choose correct letter answer, A, B. C, or D.)

A. oxygens form each water molecule bond together, DUE TO THEIR NEGATIVE CHARGES
B. hydrogens bond to oxygens of other water molecules, DUE TO HYDROGENS POSITIVE AND OXYGENS NEGATIVE CHARGE
C. hydrogens bond to each other, DUE TO THEIR POSITIVE CHARGES
D. hydrogens bond to oxygens of other water molecules, DUE TO HYDROGENS NEGATIVE AND OXYGENS POSITIVE CHARGES

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.
