Answer the following question given this paragraph: Embryonic Development (Weeks 48). Most organs develop in the embryo during weeks 4 through 8. If the embryo is exposed to toxins during this period, the effects are likely to be very damaging. Can you explain why? (Note: the drawings of the embryos are not to scale. ). Q: Exposure to toxins is most damaging during weeks 4 through 8 of the embryonic stage due to development of what during this period? Choices: - samples - faith - pain - organs A:
organs
Answer the following question given this paragraph: Atomic emission spectra are produced when excited electrons return to ground state. Q: Atomic emission spectra are produced when excited electrons return to what state? Choices: - orbital state - work state - side state - ground state A:
ground state
Q: Answer the following question given this paragraph: Another distinguishing feature of vertebrates is an endoskeleton made of bone or cartilage. Cartilage is a tough tissue that contains a protein called collagen. Bone is a hard tissue that consists of a collagen matrix, or framework, filled in with minerals such as calcium. Bone is less flexible than cartilage but stronger. An endoskeleton made of bone rather than cartilage allows animals to grow larger and heavier. Bone also provides more protection for soft tissues and internal organs. Q: What is the tough tissue that contains collagen? Choices: - membrane - muscle - fiber - cartilage A:
A: cartilage
Question: Answer the following question given this paragraph: Kinetic energy is the energy of moving matter. Things with kinetic energy can do work. Kinetic energy depends on an object's mass and velocity. Q: What is the energy of moving matter? Choices: - potential energy - binary energy - residual energy - kinetic energy A:
Answer: kinetic energy

**Answer**
33
(Q).
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? Choices: - multiplication - friction - limiting - dividing A:
(A).
dividing
