30 points! You are monitoring coral growth on a specific site for several months. Over time, you notice that some of the coral colonies are beginning to turn white and die. What process could you infer is happening on the coral reef site? (A) The coral reef is experiencing succession, so over time the coral will continue to die off gradually as the zooxanthellae algae leaves the coral polyps.

(B)The coral reef is experiencing succession, so the coral will continue to die off quickly as the zooxanthellae algae leaves the coral polyps.

C) The coral reef is experiencing climate change, so the rise in ocean temperatures is causing the coral to bleach as the zooxanthellae algae leaves the coral polyps.

(D) The coral reef is experiencing climate change, so the coral will die off from seasonal variation, which has no impact on zooxanthellae algae in the coral polyps.

Match the digestive enzymes to the macromolecules they to digest. break down fats into glycerol and fatty acids break down carbohydrates into simple sugars break down nucleic acids into nitrogenous bases and simple sugars break down proteins into amino acids

Ricardo notices that when he plays soccer in the rain, his ball does not seem to go as far after a kick. what is the best scientific question that ricardo could ask about this observation? is soccer better played in the rain or sun? how does rain affect the distance a soccer ball can travel? how does rain affect the speed of a soccer ball? is soccer affected by the rain?

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.
