Luz raises chickens for eggs. She knows that the diet a chicken eats could contribute to the number of eggs it can lay. She feeds standard chicken feed to all chicken, but separates her flock into two groups. One group is given spinach which is normal, to supplement their diet, while the other group is
given meal worms. Then she counts the number of eggs laid over a month for each group. Luz suspects that the group given meal worms will produce
more eggs. Luz's control group is...
the chickens getting meal worms.
the food she gives them
the amount of time she feeds them.
the chickens getting spinach.

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.
