Answer the following question given this paragraph: Both mitosis and meiosis result in eukaryotic cells dividing. So what is the difference between mitosis and meiosis? The primary difference is the differing goals of each process. The goal of mitosis is to produce two daughter cells that are genetically identical to the parent cell, meaning the new cells have exactly the same DNA as the parent cell. Mitosis happens when you want to grow, for example. You want all your new cells to have the same DNA as the previous cells. The goal of meiosis, however, is to produce sperm or eggs, also known as gametes . The resulting gametes are not genetically identical to the parent cell. Gametes are haploid cells, with only half the DNA present in the diploid parent cell. This is necessary so that when a sperm and an egg combine at fertilization , the resulting zygote has the correct amount of DNAnot twice as much as the parents. The zygote then begins to divide through mitosis. Q: Both mitosis and meiosis result in eukaryotic cells doing what? A:
OPTIONS:
- multiplication
- friction
- limiting
- dividing

Answer: dividing

Question: Answer the following question given this paragraph: Atoms form covalent bonds by sharing valence electrons. The valence electrons are located in atomic orbitals. However, when a bond forms, the structure of the atomic orbitals changes. In this lesson, we will see how the atomic orbitals interact to share valence electrons and form different types of covalent bonds. Q: What do atoms form by sharing valence electrons? A:
OPTIONS:
- phenotype bonds
- neutron bonds
- ionic bonds
- covalent bonds
Answer: covalent bonds

Cephalochordates have a notochord and nerve cord but no backbone. Q: Cephalochordates have a notochord and nerve cord but not a? A:
OPTIONS:
- digestive system
- nervous system
- brain
- backbone
output: backbone

Q: Answer the following question given this paragraph: Actually, almost all organisms obtain their energy from photosynthetic organisms. For example, if a bird eats a caterpillar, then the bird gets the energy that the caterpillar gets from the plants it eats. So the bird indirectly gets energy that began with the glucose formed through photosynthesis. Therefore, the process of photosynthesis is central to sustaining life on Earth. In eukaryotic organisms, photosynthesis occurs in chloroplasts . Only cells with chloroplastsplant cells and algal (protist) cellscan perform photosynthesis. Animal cells and fungal cells do not have chloroplasts and, therefore, cannot photosynthesize. That is why these organisms, as well as the non-photosynthetic protists, rely on other organisms to obtain their energy. These organisms are heterotrophs. Q: What is the function of chloroplasts that are found in plant and algal cells? A:

OPTIONS:
- mitosis
- spermatogenesis
- glycolysis
- photosynthesis

A: photosynthesis

Answer the following question given this paragraph: 6. Sound energy is a form of mechanical energy that starts with a vibration in matter. For example, the singer's voice starts with vibrations of his vocal cords, which are folds of tissue in his throat. The vibrations pass to surrounding particles of matter and then from one particle to another in waves. Sound waves can travel through air, water, and other substances, but not through empty space. Q: What is a form of mechanical energy that starts with a vibration in matter? A:
OPTIONS:
- solar energy
- electrical energy
- industrial energy
- sound energy
sound energy
