input: OPTIONS:
- the alkaline
- the chloride
- the protein
- the phosphate Now, answer this question: Answer the following question given this paragraph: The sugar of one nucleotide binds to the phosphate group of the next nucleotide. Alternating sugars and phosphate groups form the backbone of a nucleotide chain, as shown in Figure below . The bases, which are bound to the sugars, protrude from the backbone of the chain. In DNA, pairs of bases-one from each of two nucleotides-form the middle section of the molecule. Q: The sugar of one nucleotide binds to what group of the next nucleotide? A:
A:
output: the phosphate

Answer the following question given this paragraph: For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it.

OPTIONS:
- independent variable
- making a conclusion
- carbon dating

Answer the following question given this paragraph: Not all archaeans live in extreme conditions. In fact, archaeans are now known to live just about everywhere on Earth. They make up as much as 20 percent of Earth's total mass of living things. Q: What kingdom of organisms constitutes up to 20 percent of all living things on earth in mass? A:
****
A: archaeans

Answer the following question given this paragraph: The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. The representative particles can be atoms, molecules, or formula units of ionic compounds. This relationship is frequently used in the laboratory. Suppose that for a certain experiment you need 3.00 moles of calcium chloride (CaCl 2 ). Since calcium chloride is a solid, it would be convenient to use a balance to measure the mass that is needed. The molar mass of CaCl 2 is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl 2 . Dimensional analysis will allow you to calculate the mass of CaCl 2 that you should measure. Q: Who first proposed that earth is a magnet? A:
OPTIONS:
- Albert Einstein
- Isaac Newton
- Marconi
- william gilbert
william gilbert

Answer the following question given this paragraph: Most biochemical reactions take place within cells. Cells are the microscopic building blocks of organisms. Q: Where do most biochemical reactions take place? A:

- outside of cells
- within cells

Answer:
within cells
