A biologist passes blood isolated from a mouse through an affinity column containing beads. The beads have been modified to display both the antigen alone and the antigen attached to a class II MHC molecule. Some cells stick to the column while the rest wash through with a buffer wash. Which class(es) of cells would be represented by the cells that stick to the column

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
