A cell is incubated with a radioactive lipid called [3H]-palmitic acid. Membrane proteins are then isolated from the cell using multiple different treatments. High pH and high salt treatments serve to reduce the strength of ionic and hydrogen-bonding interactions. Determine the type of membrane protein that is isolated from each of these treatments.

How did the miller-urey experiment impact the way scientists think about the origins of life? use what you know about the miller-urey experiments to discuss the factors needed for life to arise, and speculate on whether life could arise on another planet.

Explain why phospholipid molecules form a bilayer. (3 marks)

Plz fast biotechnology is a growing field of applied biology. many crops such as corn have been engineered to be resistant to herbicides. therefore farmers can spray these chemicals to kill weeds growing near the crop without worries of killing the crop itself how does this type of biotechnology work? a. by changing the genetic make up of the crops. b. by causing the crops to kill the weeds. c. by changing the type of crops used. d. by changing the location of the crops.
