Forest rangers are genetically testing the deer in the forest after many were found dead. The tests determined that due to inbreeding, most deer have a genetic disease which decreases life expectancy. Based on genetic and mortality data, the rangers predict that the population of deer will be gone in 3 years. What initial concerns do the rangers most likely have?

There will be an increase in energy at the primary consumer level of organisms.

Energy available at the producer level will increase.

Less energy will be available mushrooms and earthworms.

There will not be enough energy to support the tertiary consumer population.

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.

The green colored pigment in chloroplasts is? a. nitrogen b. chlorophyll c. chlorophorm d. chlorofloromethane
