Answer the following question given this paragraph: Coefficients are used to balance chemical equations. A coefficient is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction. For example, two molecules of hydrogen would be written as 2H 2 . A coefficient of 1 usually isn't written. Q: What are used to balance chemical equations? Choices: - velocities - densities - fractions - coefficients A:
coefficients

Q: Answer the following question given this paragraph: The electrochemical potential across a membrane determines the tendency of an ion to cross the membrane. The membrane may be that of a cell or organelle or other sub cellular compartment. The electrochemical potential arises from three factors:. Q: The electrochemical potential across a membrane determines the tendency of an ion to do what? Choices: - attach to the membrane - move away from the membrane - destroy the membrane - cross the membrane A:
A: cross the membrane
Question: Answer the following question given this paragraph: Bones are far from static, or unchanging. Instead, they are dynamic, living tissues that are constantly being reshaped. Under the direction of osteocytes, osteoblasts continuously build up bone, while osteoclasts continuously break it down. You can watch an animated video of these processes in bone at http://www. youtube. com/watch?v=yENNqRJ2mu0 . Q: Bones are far from static, or unchanging. instead, they are what? Choices: - continuous - stable - fluid - dynamic A:
Answer: dynamic

Answer the following question given this paragraph: Remember that proteins are made out of amino acids. How does the information in the gene get converted from the language of nucleotides to the language of amino acids? The process is called translation . The amino acids are placed in a specific order during translation. The order is specified by the codons in the mRNA, which is produced during transcription. As the mRNA sequence is based on the gene sequence in the DNA, the order of amino acids that makes the protein is based on the gene sequence as well. Q: What is the name for the process where data in the genes is transferred to amino acids? Choices: - mutation - transpiration - generation - translation A:
**Answer**
translation
