Answer:
disrupting membrane integrity
Explanation:
Surfactants work by disrupting membrane integrity. Surfactants disrupt cell membrane integrity by absorbing at the cell membrane and destroying the cell membranes bilayer thus lowering the surface tension of the cell which results in leaky spots resulting in the cell being more permeable.
The best example is roots and stems
This is a difficult question because the paragraph says that the scientists found the crater was dated back to the time the dinosaurs became extinct according to the fossil record, so that would make it true, but what it does not say is where they got the fossil record from or how the fossil record is correct, so that would make it false. So I would put it in as false.
Yes, C4 is a process used by plants to survive in hot dry climates along with the CAM cycle. Hope this helps!
<span>For the first step, you must isolate the cells from the media. The cells contain the DNA so you keep the cells and pellet.
The next step would be a cell lysis which causes the cells to open and the DNA to come out. At this point you would keep the supernatant, as the pellet is the cell membrane and other parts of the cell.
The chelex is to bind to transition metal ions. This would cause and DNases in the cell to become inactive because the metal ion is their cofactor. The pellet in this case would contain the chelex and the DNA would still be in the supernatant.</span>
