Question: Answer the following question given this paragraph: All alkanes are composed of carbon and hydrogen atoms, and have similar bonds, structures, and formulas; noncyclic alkanes all have a formula of CnH2n+2. The number of carbon atoms present in an alkane has no limit. Greater numbers of atoms in the molecules will lead to stronger intermolecular attractions (dispersion forces) and correspondingly different physical properties of the molecules. Properties such as melting point and boiling point (Table 20.1) usually change smoothly and predictably as the number of carbon and hydrogen atoms in the molecules change. Properties of Some Alkanes[3] Alkane. Q: All alkanes are composed of carbon and hydrogen atoms, and have similar bonds, structures, and formulas; noncyclic alkanes all have a formula of cnh2n+2. the number of carbon atoms present in an alkane has what? A:
OPTIONS:
- done limit
- crippling limit
- such limit
- no limit
Answer: no limit

input with options: Answer the following question given this paragraph: Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane , or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus. Q: The cytoplasm is all the contents of the cell inside the cell membrane, with the exception of what? A:
OPTIONS:
- vacuole
- lysosome
- molecules
- nucleus
output: nucleus

Q: Answer the following question given this paragraph: Momentum is a vector quantity that has the same direction as the velocity of the object. Q: Momentum is a vector quantity that has the same direction as what? A:

OPTIONS:
- object energy
- initial speed
- inertia
- object ' s velocity

A: object ' s velocity

input: OPTIONS:
- hectase ii
- cyclohexane ii
- chromosome ii
- metaphase ii Now, answer this question: Answer the following question given this paragraph: Metaphase II: The chromosomes line up one on top of each other along the middle of the cell, similar to how they line up in mitosis. The spindle is attached to the centromere of each chromosome. Q: In which stage do chromosomes line up one on top of each other along the middle of the cell, similar to how they line up in mitosis? A:
A:
output: metaphase ii

Question: Answer the following question given this paragraph: The formation of scientific theories is generally guided by the law of parsimony. The word parsimony means "thriftiness. " The law of parsimony states that, when choosing between competing theories, you should select the theory that makes the fewest assumptions. In other words, the simpler theory is more likely to be correct. For example, you probably know that Earth and the other planets of our solar system orbit around the sun. But several centuries ago, it was believed that Earth is at the center of the solar system and the other planets orbit around Earth. While it is possible to explain the movement of planets according to this theory, the explanation is unnecessarily complex. Q: What the scientific concept stating that when looking at two competing theories, the one with fewer assumptions should be chosen? A:
OPTIONS:
- law of thermodynamics
- law of simplicity
- law of averages
- law of parsimony
Answer:
law of parsimony
