What is one hypothesis to explain the diversity of life (especially the honeycreepers) on the Islands? Question 5 options:

Isolation from parent population and random mutation caused the populations of honeycreepers to evolve and become different enough to be considered a new species.

Isolation and lots of predators played a major role in creating new species of honeycreepers

The islands started out extremely bare, so it was really hard for any mammals to get to the island.

All of the above

What are the four basic classes of organic molecules how do they differ structurally and functionally

The shift of a vehicle's weight around its center of gravity is known as

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.
