What is the difference between the first and second laws of thermodynamics? provide two scenarios that exemplify each.

The first law states that energy can be neither created nor destroyed. All machines work on first law of thermodynamics. An example of this is a light bulb. A light bulb transforms electrical energy into light and heat energy.

The second law states that the state of entropy of the entire universe will always increase over time. An example of this is when something is caught under fire. When something is on fire, we pour water because, according to the second law, heat from the fire (high temperature) will flow to the water (lower temperature).

Hope this helps! :-)

google my dude. if it doesn't show up ask me.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
