bucket of water, which of the statements would be true
n n n n n n n n n



?

a. The entropy of the bucket of water would be gr

eater.
b. The entropy of the bucket of water and the e

n n n n n n



c. The entropy of the dog would be greater. -
n n n n n n n n



ANSWER >>>>a. The entropy of the bucket of water

, would be greater. (To maintain itself as a living organis

ut of energy. A bucket of water will remain a bucket of
n n n n n n n n n n n n



water without input of energy. In fact, if you add energy

to water, it may change its state to a gas and become

Suppose that a researcher claimed to have created a n n n n n n n n n



genetically modified plant that produces twice as muc n n n n n n n



h energy as it harnesses from its environment. How co
n n n n n n n n n



uld this be possible?
n n n




a. This is impossible because such a plant would vi

b. The researcher has likely doubled the amount of D
n n n n n n n n



NA present in the plant's genome.
n n n n n



c. The researcher has inserted genes into the plant's
n n n n n n n n



genome that increase the amount of work the plant is c

apable of performing. n n



d. The researcher has inserted a mutation into the pla

produced.
e. The researcher has found a way to decrease the ov
