Answer the following question given this paragraph:   Figure 7.8 Following meiosis, each gamete has one copy of each chromosome. Nondisjunction occurs when homologous chromosomes (meiosis I) or sister chromatids (meiosis II) fail to separate during meiosis.   Q: Each gamete will have one copy of each chromosome following which process involving cell division?   A:
****
A: meiosis

Answer the following question given this paragraph:   Flatworms reproduce sexually. In most species, the same individuals produce both eggs and sperm. After fertilization occurs, the fertilized eggs pass out of the adult’s body and hatch into larvae. There may be several different larval stages. The final larval stage develops into the adult form, and the life cycle repeats.   Q: Flatworms reproduce sexually. in most species, the same individuals produce both what?   A:
OPTIONS:
- gametes
- heart and sperm
- diploid and haploid
- eggs and sperm
eggs and sperm

Answer the following question given this paragraph:   Flagella ( flagellum , singular) are long, thin structures that protrude from the cell membrane. Both eukaryotic and prokaryotic cells can have flagella. Flagella help single-celled organisms move or swim towards food. The flagella of eukaryotic cells are normally used for movement too, such as in the movement of sperm cells, which have only a single flagellum. The flagella of either group are very different from each other. Prokaryotic flagella, shown in Figure below , are spiral-shaped and stiff. They spin around in a fixed base much like a screw does, which moves the cell in a tumbling fashion. Eukaryotic flagella are made of microtubules that bend and flex like a whip.   Q: What are the long, thin structures that protrude from the cell membrane and help single-celled organisms move or swim towards food?   A:
OPTIONS:
- microvilli
- tentacles
- sporangia
- flagella

Answer: flagella

Question: Answer the following question given this paragraph:   Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone.   Q: What does cartilage lack compared to bones, making it softer and less rigid?   A:
OPTIONS:
- potassium
- magnesium
- protein
- calcium
Answer: calcium

input: OPTIONS:
- protons
- electrons
- nuclei
- neutrons Now, answer this question: Answer the following question given this paragraph:   An atom’s mass number is its mass in atomic mass units (amu), which is about equal to the total number of protons and neutrons in the atom. Different isotopes of an element have different mass numbers because they have different numbers of neutrons.   Q: Different isotopes of an element have different mass numbers because they have different numbers of what?   A:
A:
output:

assistant: neutrons
