Answer:

C. Cholesterol

Explanation:

Cholesterol maintains the fluidity of the cell membrane and thereby, regulates its function.

Bile acids are derived from cholesterol which serves as their precursor. For example, Taurocholic acid is a polar derivative of cholesterol. Bile acids serve in the absorption of fatty acids, glycerol, and fat-soluble vitamins as these compounds are non-polar in nature.  

Vitamin D is produced when the derivative of cholesterol, 7-dehydrocholesterol undergoes photolysis in skin cells in presence of sunlight.

Dmitriy789 [7]

Explanation:

D) 75 J

Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.

With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

How would dna extracted from an onion be different from dna extraction from cauliflower?
JulsSmile [24]
Dna extration from a onion and from a cauliflower would be different because even though all DNA is composed by the same nucleotides (A, T, C and G), the sequence of their genes will be different. That difference is why a cauliflower doesn't look like a onion. The cauliflower has genes that, when expressed, make the organism look like cauliflower and nothing else..
