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? Choices: - done limit - crippling limit - such limit - no limit A:
no limit

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? Choices: - vacuole - lysosome - molecules - nucleus A:
(Answer)
nucleus

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? Choices: - hectase ii - cyclohexane ii - chromosome ii - metaphase ii A:
(A).
metaphase ii
Ques:Answer the following question given this paragraph: The amount of power passed through transmission lines can be calculated by multiplying voltage by current. The same power can be transmitted using a very high voltage and a very low current as with a low voltage and high current. Q: The amount of power passed through transmission lines can be calculated by multiplying voltage by what? Choices: - resistance - amplification - induction - current A:

Ans:current
