Answer the following question given this paragraph: The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins . Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK) . Cyclins comprise a group of proteins that are rapidly produced at key stages in the cell cycle. Once activated by a cyclin, CDK are enzymes that activate or inactivate other target molecules through phosphorylation. It is this precise regulation of proteins that triggers advancement through the cell cycle. Leland H. Hartwell, R. Timothy Hunt, and Paul M. Nurse won the 2001 Nobel Prize in Physiology or Medicine for their discovery of these critical proteins. Q: What are cyclins made up of? A:
OPTIONS:
- enzymes
- group of sugars
- steroids
- group of proteins

Answer: group of proteins

Question: Answer the following question given this paragraph: The supertree also shows that another major diversification of mammals occurred about 50 million years ago. Again, worldwide climate change may have been one reason. This time Earth's temperature rose. The warmer temperature led to a greater diversity of plants. This would have meant more food for mammals or their prey. Q: A major diversification of what animal group occurred about 50 million years ago, possibly spurred by worldwide climate change? A:
OPTIONS:
- reptiles
- amphibians
- insects
- mammals
Answer: mammals

input with options: Answer the following question given this paragraph: According to the Aufbau process, sublevels and orbitals are filled with electrons in order of increasing energy. Since the s sublevel consists of just one orbital, the second electron simply pairs up with the first electron as in helium. The next element is lithium and necessitates the use of the next available sublevel, the 2 s . Q: According to which process, sublevels and orbitals are filled with electrons in order of increasing energy? A:
OPTIONS:
- Schrodinger's cat
- hausen
- particle dynamics
- aufbau
output: aufbau

Q: Answer the following question given this paragraph: Eventually a main sequence star will use up all of its hydrogen. It then starts to fuse helium atoms into larger elements like carbon. At this time, the star's core will collapse inward. The star's outer layers will spread out and cool. The result is a larger star that is cooler on the surface, and red in color. The star is now a red giant . Q: When a star's core collapses inward while the outer layers spread and cool, what "colorful" celestial body forms? A:

OPTIONS:
- blue giant
- green giant
- white giant
- red giant

A: red giant

input: OPTIONS:
- working muscles
- active muscles
- bone muscles
- skeletal muscles Now, answer this question: Answer the following question given this paragraph: Skeletal muscles are attached to the skeleton and cause bones to move when they contract. Q: Which types of muscles cause bones to move when they retract? A:
A:
output: skeletal muscles

Question: Answer the following question given this paragraph: f 2 = v w / 2 = v w / 2L = 2 f 1 . Similarly, f 3 = 3 f 1 , and so on. All of these frequencies can be changed by adjusting the tension in the string. The greater the tension, the greater v w is and the higher the frequencies. This observation is familiar to anyone who has ever observed a string instrument being tuned. We will see in later chapters that standing waves are crucial to many resonance phenomena, such as in sounding boxes on string instruments. Q: Stringed instruments can help show the relationship between tension and what in strings? A:
OPTIONS:
- volumes
- temperatures
- lengths
- frequencies
Answer:
frequencies
