Answer the following question given this paragraph: Carbon sequestration is any way of removing carbon dioxide from the atmosphere and storing it in another form. Carbon is sequestered naturally by forests. Trees take in carbon dioxide for photosynthesis. Artificial methods of sequestering carbon underground are being researched. Q: What term refers to any method of removing carbon dioxide from the atmosphere and storing it in another form? A:

OPTIONS:
- carbon footprint
- carbon metamorphosis
- carbon transfer
- carbon sequestration

Answer: carbon sequestration

Problem: OPTIONS:
- free energy
- experimental energy
- subsequent energy
- electrical energy
Q: Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. The electrons flow and create electric current. Figure below and the animation at the URL below show how a solar cell uses light energy to produce electric current and power a light bulb. Many calculators and other devices are also powered by solar cells. Q: What do solar cells convert the energy in sunlight into? A:
Answer: electrical energy

Problem:OPTIONS:
- the metabolism
- pancreas
- kidney
- the stomach

Answer the following question given this paragraph: Q: The contents of which organ are mixed every 20 seconds? A:
****
A: the stomach

Answer the following question given this paragraph: Populations may show different patterns of growth. The growth pattern depends partly on the conditions under which a population lives. Two common growth patterns are exponential growth and logistic growth. Both are represented in Figure below . Q: What are 2 common growth patterns of population? A:
OPTIONS:
- migratory and logistic
- exponential and economical
- organic and inorganic
- exponential and logistic
exponential and logistic

Answer the following question given this paragraph: The double helical nature of DNA, together with the findings of Chargaff, demonstrated the base-pairing nature of the bases. Adenine always pairs with thymine, and guanine always pairs with cytosine ( Figure below ). Because of this complementary nature of DNA, the bases on one strand determine the bases on the other strand. These complementary base pairs explain why the amounts of guanine and cytosine are present in equal amounts, as are the amounts of adenine and thymine. Adenine and guanine are known as purines . These bases consist of two ring structures. Purines make up one of the two groups of nitrogenous bases. Thymine and cytosine are pyrimidines , which have just one ring structure. By having a purine always combine with a pyrimidine in the DNA double helix, the distance between the two sugar-phosphate backbones is constant, maintaining the uniform shape of the DNA molecule. Q: What distinctive configuration of dna demonstrates the base-pairing nature of the bases? A:
OPTIONS:
- single helix
- double loop
- triple helix
- double helix

Answer: double helix

input with options: Answer the following question given this paragraph: osmol = M i If more than one solute is present in a solution, the individual osmolarities are additive to get the total osmolarity of the solution. Solutions that have the same osmolarity have the same osmotic pressure. If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from the lower-osmolarity solution to the higher-osmolarity solution. Counterpressure exerted on the highosmolarity solution will reduce or halt the solvent transfer. An even higher pressure can be exerted to force solvent from the high-osmolarity solution to the low-osmolarity solution, a process called reverse osmosis. Reverse osmosis is used to make potable water from saltwater where sources of fresh water are scarce. Q: If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from what to what, in terms of osmolarity of the solution? A:
OPTIONS:
- low to low
- high to high
- high to low
- low to high
output:
low to high
