You decide to test peptides 1 and 2 using an in vivo model (in mice). for this experiment, you prepare tissue grafts loaded with a starting culture of wild-type s. aureus and surgically implant them into mice. in the control treatment, you don't add either peptide to the graft. you run six different experimental treatments in which you add each peptide alone to the graft, or you add both peptides to the graft. you also test a single dose of peptide versus three doses spread out over the experiment. after seven days, you remove the grafts and measure the amount of toxin present. your results are shown below.

"griffith's experiment discovering the "transforming principle" in pneumococcus bacteria. griffith's experiment, reported in 1928 by frederick griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation." - griffith's experiment.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
