Answer the following question given this paragraph: Like equations in math, equations in chemistry must balance. There must be the same number of each type of atom in the products as there is in the reactants. In equation 1, count the number of hydrogen and oxygen atoms on each side of the arrow. There are two hydrogen atoms in both reactants and products. There are two oxygen atoms in the reactants but only one in the product. Therefore, equation 1 is not balanced. Q: What do you call the atomic "ingredients" that go into a chemical reaction? Choices: - propellants - complexes - Starters - reactants A:
reactants
Answer the following question given this paragraph: Composition of Body Fluids The compositions of the two components of the ECFplasma and IFare more similar to each other than either is to the ICF (Figure 26.5). Blood plasma has high concentrations of sodium, chloride, bicarbonate, and protein. The IF has high concentrations of sodium, chloride, and bicarbonate, but a relatively lower concentration of protein. In contrast, the ICF has elevated amounts of potassium, phosphate, magnesium, and protein. Overall, the ICF contains high concentrations of potassium and phosphate ( HPO 24 ), whereas both plasma and the ECF contain high concentrations of sodium and chloride. Q: What are the two components of the ecf? Choices: - proteins and if - polymer and if - solids and if - plasma and if A:
plasma and if
Q: Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. Solar cells are also called photovoltaic (PV) cells because they use light ( photo- ) to produce voltage ( -voltaic ). Solar cells contain a material such as silicon that absorbs light energy. The energy knocks electrons loose so they can flow freely and produce a difference in electric potential energy, or voltage. The flow of electrons creates electric current. Solar cells have positive and negative contacts, like the terminals in chemical cells. If the contacts are connected with wire, current flows from the negative to positive contact. The Figure below and following URL show how a solar cell works. http://www. suntreksolar. com/solarElectricity/howCellsWork. asp. Q: Solar cells convert the energy in sunlight to what type of energy? Choices: - active energy - radical energy - stellar energy - electrical energy A:
A: electrical energy
Question: Answer the following question given this paragraph: The gonads secrete sex hormones. The male gonads are called testes . They secrete the male sex hormone testosterone. The female gonads are called ovaries . They secrete the female sex hormone estrogen. Sex hormones are involved in the changes of puberty. They also control the production of gametes by the gonads. Q: The testes produce what hormone? Choices: - dopamine - insulin - estrogen - testosterone A:
Answer: testosterone

Answer the following question given this paragraph: A protein is an organic compound made up of small molecules called amino acids . There are 20 different amino acids commonly found in the proteins of living organisms. Small proteins may contain just a few hundred amino acids, whereas large proteins may contain thousands of amino acids. The largest known proteins are titins, found in muscle, which are composed from over 27,000 amino acids. Q: What are the largest known proteins called? Choices: - obscures - sporozoans - aminos - titins A:
**Answer**
titins
