A cell membrane completely made of a polar substance would be completely permeable to all ions present in the extracellular environment, thus disrupting unique ionic composition within the cell.
Each increase/decrease on the scale is by a factor of 10. 2-4 is two factors, 10x10. Lemon is 100 times more acidic
The answer is ion channel! hope this helped :)
Answer:

Explanation:
The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.
Artificial Selection or “ Selective Breeding”. aka the process by which humans use animal breeding and plant breeding to selectively
