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:
cartilage

Answer the following question given this paragraph: A day or two after an ovary releases an egg, the egg may unite with a sperm. Sperm are deposited in the vagina during sexual intercourse. They propel themselves through secretions in the uterus and enter a fallopian tube. This is where fertilization normally takes place. Q: Sperm propel themselves through secretions in the uterus and enter what tube? Choices: - gaseous - ovarian - uterine - fallopian A:
(Answer)
fallopian
Ques: Answer the following question given this paragraph: Metals such as iron are useful for many purposes because of their unique properties. For example, they can conduct electricity and bend without breaking. However, pure metals may be less useful than mixtures of metals with other elements. For example, adding a little carbon to iron makes it much stronger. This mixture is called steel. Steel is so strong that it can hold up huge bridges, like the one pictured above. Steel is also used to make skyscrapers, cargo ships, cars, and trains. Steel is an example of an alloy. Q: Adding carbon to iron makes what type of metal? Choices: - ions - titanium - plastic - steel A:
Ans: steel

Answer the following question given this paragraph: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. Q: What is the measure of kinetic energy of the particles in matter? Choices: - energy - precipitation - friction - temperature A:
(A).
temperature
Ques:Answer the following question given this paragraph: Glial Cells of the PNS One of the two types of glial cells found in the PNS is the satellite cell. Satellite cells are found in sensory and autonomic ganglia, where they surround the cell bodies of neurons. This accounts for the name, based on their appearance under the microscope. They provide support, performing similar functions in the periphery as astrocytes do in the CNSexcept, of course, for establishing the BBB. The second type of glial cell is the Schwann cell, which insulate axons with myelin in the periphery. Schwann cells are different than oligodendrocytes, in that a Schwann cell wraps around a portion of only one axon segment and no others. Oligodendrocytes have processes that reach out to multiple axon segments, whereas the entire Schwann cell surrounds just one axon segment. The nucleus and cytoplasm of the Schwann cell are on the edge of the myelin sheath. The relationship of these two types of glial cells to ganglia and nerves in the PNS is seen in Figure 12.12. Q: Satellite and schwann cells are the two types of what kind of cell found in the pns? Choices: - dendritic - osteoclast - epidermal - glial A:

Ans:glial
Question: Answer the following question given this paragraph: Floods may occur when deep snow melts quickly in the spring. More often, floods are due to heavy rainfall. Floods happen when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams. Q: What occurs when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams? Choices: - typhoons - greenhouse effect - landslides - floods A:
Answer:
floods
