5 The graphs below shows the rate of water conduction up three different trees in a forest over 24 hours 25 Free A 204 15 rate of water conduction Idm per hour 1.04 tree B 05 free C 18 12 time 5.1 52 Describe the rate of water conduction in tree A during this 24-hour period. Use the data on the graphs to support your answer (3) Suggest how the ecologists used the data in the graphs to calculate the total volume of water used by a tree in 24 hours. (2) Indicate which tree is a tall tree, a medium-height tree and a short tree? (3) Suggest reasons for the different rates of water conduction in the three trees (2) 5.3 5.4sugesst reason for different rates of water conduction in three trees (10)​

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.
