Because vaccines are fairly common today,, it is hard to imagine the terrible risk a colonial person took when undergoing inoculation. It isn’t known whether Cotton Mather ordered his son to undergo "ye operation," or simply encouraged him to do so, leaving Sammy to make his own decision. It is known that Dr. Boylston, the local doctor who actually administered the inoculations, included his own slave and the slave’s toddler son. The name of the slave has not come down through history, but we do know his child was called Jackie. What dangers did these three people face from the inoculating material itself, or from the procedure and its possible side effects? What may have been their thoughts as they took part?

Eristics do scientists use to distinguish between organisms in different kingdoms

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.
