Ques:Answer the following question given this paragraph: The sliding-and-shortening process occurs all along many myofibrils and in many muscle fibers. It causes the muscle fibers to shorten and the muscle to contract. Q: What part of the muscle fibers cause shortening and contraction? Choices: - fasciae - pores - collagen - myofibrils A:

Ans:myofibrils

Ques:Answer the following question given this paragraph: Continuous Capillaries The most common type of capillary, the continuous capillary, is found in almost all vascularized tissues. Continuous capillaries are characterized by a complete endothelial lining with tight junctions between endothelial cells. Although a tight junction is usually impermeable and only allows for the passage of water and ions, they are often incomplete in capillaries, leaving intercellular clefts that allow for exchange of water and other very small molecules between the blood plasma and. Q: What is the most common type of capillary? Choices: - channels - large - ending - continuous A:

Ans:continuous

Ques:Answer the following question given this paragraph: In other materials, there are regions where the north and south poles of atoms are all lined up in the same direction. These regions are called magnetic domains . Generally, the magnetic domains point in different directions, so the material is still not magnetic. However, the material can be magnetized (made into a magnet) by placing it in a magnetic field. When this happens, all the magnetic domains line up, and the material becomes a magnet. You can see this in the Figure below . Materials that can be magnitized are called ferromagnetic materials . They include iron, cobalt, and nickel. Q: The regions of a material where the north and south poles of atoms are aligned are called what? Choices: - magnetic rays - cores - observed domains - magnetic domains A:

Ans:magnetic domains
