Answer the following question given this paragraph: Figure 11.7 Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. Q: Meiosis and mitosis are both preceded by one round of what? Choices: - internal fertilization - germination - cellular respiration - dna replication A:
dna replication
Answer the following question given this paragraph: Hydrogen peroxide is commonly sold as a 3% by volume solution for use as a disinfectant. Q: Hydrogen peroxide is commonly sold as a 3% by volume solution for use as a what? Choices: - detergent - antiseptic - surfactant - disinfectant A:
disinfectant
Q: Answer the following question given this paragraph: Plasma cells are activated B cells that secrete antibodies. Antibodies are large, Y-shaped proteins that recognize and bind to antigens. Plasma cells are like antibody factories, producing many copies of a single type of antibody. The antibodies travel throughout the body in blood and lymph. Each antibody binds to just one kind of antigen. When it does, it forms an antigen-antibody complex (see Figure below ). The complex flags the antigen-bearing cell for destruction by phagocytosis . Q: What do you call large, y-shaped proteins that recognize and bind to antigens? Choices: - proteins - membranes - parasites - antibodies A:
A: antibodies
Question: Answer the following question given this paragraph: The two ribosomal subunits are named base on their sedmentation rate in a centrifuge. The unit of measurement is the Svedberg unit , a measure of the rate of sedimentation, not the size. This accounts for why fragment names do not add up (70S is made of 50S and 30S). Q: The svedberg unit is a measure of the rate of what, which is tested in a centrifuge? Choices: - precipitation - temperature - secretion - sedimentation A:
Answer: sedimentation

Answer the following question given this paragraph: A : A theory is needed to explain gravity. In science, a theory is a broad explanation that is supported by a great deal of evidence. Q: What is another name for a broad explanation that is supported by a great deal of evidence? Choices: - hypothesis - concept - conjecture - theory A:
**Answer**
theory
Q: Answer the following question given this paragraph: Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds. Q: What type of gases are the least reactive of all elements? Choices: - brave - humble - lucky - noble A:
A: noble
