Sandra has a houseplant sitting on her kitchen windowsill, where it receives a lot of sunlight.

What will most likely be the plant’s pattern of growth?

The cells on the shaded side of the plant will grow longer, causing the opposite side of the plant to grow toward the window.
A. The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
B. The cells on the sunny side of the plant will grow longer, causing the shaded side of C. the plant to grow away from the window.
D. The cells on the sunny side of the plant will shrink, causing the shaded side of the plant to grow away from the window.

What kind of seafood would you expect to have the highest levels of mercury and why? kelp, because they use the sun to photosynthesize on the bottom trophic level. oysters, because they filter feed on plankton on a lower trophic level. small fish, because they eat plankton on a higher trophic level. sharks, because they feed on organisms on a higher trophic level.

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.
