Question: Answer the following question given this paragraph: The process that produces haploid gametes is meiosis. Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of the organisms. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair. Two cell divisions occur during meiosis, and a total of four haploid cells are produced. The two cell divisions are called meiosis I and meiosis II. The overall process of meiosis is summarized in Figure below . You can watch an animation of meiosis at this link: http://www. youtube. com/watch?v=D1_-mQS_FZ0 . Q: What is the type of cell division where the number of chromosomes is reduced in half? A:
OPTIONS:
- cloning
- mitosis
- interphase
- meiosis
Answer: meiosis

input with options: Answer the following question given this paragraph: Because the hydroxyl radical has an unpaired electron, it is highly reactive. (This is true of any substance with unpaired electrons, known as a free radical. ) This hydroxyl radical can react with all kinds of biological molecules (DNA, proteins, enzymes, and so on), causing damage to the molecules and disrupting physiological processes. Examples of direct and indirect damage are shown in Figure 21.32. Q: The hydroxyl radical is highly reactive because it has what? A:
OPTIONS:
- unpaired neutron
- paired proton
- paired electron
- unpaired electron
output: unpaired electron

Q: Answer the following question given this paragraph: Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. Concentration refers to the number of particles of a substance per unit of volume. The more particles of a substance in a given volume, the higher the concentration. A substance always moves from an area where it is more concentrated to an area where it is less concentrated. It's a little like a ball rolling down a hill. It goes by itself without any input of extra energy. Q: What type of transport occurs when substances cross the plasma membrane without any input of energy from the cell? A:

OPTIONS:
- physical transport
- wave diffusion
- active transport
- passive transport

A: passive transport

input: OPTIONS:
- source
- material
- food
- energy Now, answer this question: Answer the following question given this paragraph: Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Q: Heat, electricity, or light might provide what necessary input to the process of decomposition? A:
A:
output: energy
