100 points and Brainliest Anwser ASAP Jeff wants to make a biofuel to power his car (biofuel is a fuel that is made from renewable energy sources unliketraditional gasoline or coal) After doing reseach, Jeff has three options from which he will make his fuel: Sunflower oil, peanut oil, and vegtable oil 1> Design an experiment Jeff can perform in order to test there three fuels and how they perform in his car 2. What is the Independant variable? 3. What is the dependant variable 4. What are two control variables in your experiment?

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.
