How does the structure of a phospholipid allow it to function as a cell membrano component ? A The non- polar regions of the phospholipid tails orient toward each other with the polar regions of the phospholipids pointing toward the inside of the cytoplasm or towards B The inner non- polar region of the phospholipid bilayer is extremely attractive to water moleculos , making the cell membrano semipermeable С Phospholipids can shift the polar regions and the non - polar rogions so can frequently within plasma mombrano D Phospholipids are very polar therefore they disperse easily in water .

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
