Answer the following question given this paragraph: Four unifying principles form the basis of biology. Whether biologists are interested in ancient life, the life of bacteria, or how humans could live on the moon, they base their overall understanding of biology on these four principles:. Q: Whether focused on ancient life, the life of bacteria, or how humans could live on the moon, four unifying principles form the basis of what branch of science? A:
OPTIONS:
- electronics
- chemistry
- geology
- biology

Answer: biology

Question: Answer the following question given this paragraph: Energy is the ability to change or move matter. All living things need energy. They need energy for everything they do, whether it is to move long distances or simply to carry out basic biochemical processes inside cells. Energy enters most ecosystems in the form of sunlight. In a few ecosystems, energy enters in the form of chemical compounds. All ecosystems need a constant input of energy in one of these two forms. Q: What is the ability to change or move matter? A:
OPTIONS:
- volume
- temperature
- density
- energy
Answer: energy

input with options: Answer the following question given this paragraph: Restriction enzymes or restriction endonucleases are prokaryotic enzymes that recognize and cut DNA at specific sequences, called restriction sites. It is believed that they evolved as a defense mechanism against foreign DNA, such as viral DNA. Over 3,000 restriction enzymes have been identified. Some of the more common restriction enzymes are shown in the table below, where up and down arrows show the sites of cleavage. Restriction enzymes are named based on the prokaryotic organism they are isolated from. For example, those isolated from Escherichia coli would begin with Eco. As the Table below shows, digestion with the restriction enzymes will result in overlapping or blunt ends. EcoRI produces overlapping "sticky" ends: the enzyme cleaves between the G and A on both strands. On the other hand, SmaII restriction enzyme cleavage produces "blunt" ends. The enzyme cleaves between the G and C on both strands. Q: Restriction enzymes or restriction endonucleases are prokaryotic enzymes that recognize and cut what at specific sequences? A:
OPTIONS:
- mitochondria
- bacteria
- rna
- dna
output: dna

Q: Answer the following question given this paragraph: data are passed to new generations; and even how proteins are built to required specifications. All these abilities depend on the pairing of complementary bases. Figure 19.7 "Complementary Base Pairing" shows the two sets of base pairs and illustrates two things. First, a pyrimidine is paired with a purine in each case, so that the long dimensions of both pairs are identical (1.08 nm). If two pyrimidines were paired or two purines were paired, the two pyrimidines would take up less space than a purine and a pyrimidine, and the two purines would take up more space, as illustrated in Figure 19.8 "Difference in Widths of Possible Base Pairs". If these pairings were ever to occur, the structure of DNA would be like a staircase made with stairs of different widths. For the two strands of the double helix to fit neatly, a pyrimidine must always be paired with a purine. The second thing you should notice in Figure 19.7 "Complementary Base Pairing" is that the correct pairing enables formation of three instances of hydrogen bonding between guanine and cytosine and two between adenine and thymine. The additive contribution of this hydrogen bonding imparts great stability to the DNA double helix. Q: The "double helix" shape is associated with what substance found in cells? A:

OPTIONS:
- genes
- bacteria
- plasma
- dna

A: dna

input: OPTIONS:
- tropical gusts
- cyclones
- doldrums
- trade winds Now, answer this question: Answer the following question given this paragraph: The wind belts have names. The Trade Winds are nearest the Equator. The next belt is the westerlies. Finally are the polar easterlies. The names are the same in both hemispheres. Q: What is the name of the wind belt nearest the equator? A:
A:
output: trade winds

Question: Answer the following question given this paragraph: A friend whispers to you in class in a voice so soft that you have to lean very close to hear what he's saying. Later that day, your friend shouts to you across the football field. Now his voice is loud enough for you to hear him clearly even though he's many meters away. Obviously, sounds can vary in loudness. Loudness refers to how loud or soft a sound seems to a listener. The loudness of sound is determined, in turn, by the intensity of sound. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB) . Q: What is the measure of the amount of energy found in sound waves? A:
OPTIONS:
- decibels
- density
- frequency
- intensity
Answer:
intensity
