Answer the following question given this paragraph: The process of protein synthesis is summarized in the Figure below . DNA produces an RNA template that directs the amino acids to be introduced into the growing protein chain in the proper sequence. A specific transfer RNA attaches to each amino acid and brings it to the RNA for incorporation. Q: What directs the amino acids to be introduced into the growing protein chain in the proper sequence? Choices: - organism template - gene template - organelle template - rna template A:
rna template

Answer the following question given this paragraph: Atoms have protons and neutrons in the center, making the nucleus, while the electrons orbit the nucleus. The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different. What makes atoms of different elements different? The fundamental characteristic that all atoms of the same element share is the number of protons. All atoms of hydrogen have one and only one proton in the nucleus; all atoms of iron have 26 protons in the nucleus. This number of protons is so important to the identity of an atom that it is called the atomic number of the element. Thus, hydrogen has an atomic number of 1, while iron has an atomic number of 26. Each element has its own characteristic atomic number. Atoms of the same element can have different numbers of neutrons, however. Atoms of the same element (i. , atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus. However, a small number (about one in a million) of hydrogen atoms have a proton and a neutron in their nuclei. This particular isotope of hydrogen is called deuterium. A very rare form of hydrogen has one proton and two neutrons in the nucleus; this isotope of hydrogen is called tritium. The sum of the number of protons and neutrons in the nucleus is called the mass number of the isotope. Saylor URL: http://www. saylor. org/books. Q: All atoms of the same element share the same number of what type of particle? Choices: - quarks - neutrons - nucleus - protons A:
**Answer**
protons
Answer the following question given this paragraph: The strength of bases is measured on a scale called the pH scale, which ranges from 0 to 14. On this scale, a pH value of 7 indicates a neutral solution, and a pH value greater than 7 indicates a basic solution. The higher the pH value is, the stronger the base. The strongest bases, such as drain cleaner, have a pH value close to 14. Q: The strength of bases is measured on what scale? Choices: - acid test - litmus test - pneumatic scale - ph scale A:
ph scale
