Answer the following question given this paragraph: Cells, like these nerve cells, do not work in isolation. To send orders from your brain to your legs, for example, signals pass through many nerve cells. These cells work together to perform a similar function. Just as muscle cells work together, bone cells and many other cells do as well. A group of similar cells that work together is known as a tissue. Q: When orders are sent from your brain to your legs, these signals pass through what type of cells? Choices: - mobility cells - molecules - skin cells - nerve cells A:
nerve cells
Answer the following question given this paragraph: Red blood cells are flat, round, and very small. Their small size allows easy maneuverability through the capillaries, the narrowest blood vessels, where oxygen is transferred into body cells. Q: What are the narrowest blood vessels, where oxygen is transferred into body cells? Choices: - arteries - muscles - viens - capillaries A:
capillaries
Q: Answer the following question given this paragraph: An innate behavior is any behavior that occurs naturally in all animals of a given species. An innate behavior is also called an instinct . The first time an animal performs an innate behavior, the animal does it well. The animal does not have to practice the behavior in order to get it right or become better at it. Innate behaviors are also predictable. All members of a species perform an innate behavior in the same way. From the examples described above, you can probably tell that innate behaviors usually involve important actions, like eating and caring for the young. Q: What type of behavior occurs naturally in all animals of a given species? Choices: - learned - observational - reflex - innate A:
A: innate
Question: Answer the following question given this paragraph: Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level. Q: The number of electrons in the outer energy level determines what property of nonmetals? Choices: - density - permeability - vibration - reactivity A:
Answer: reactivity

Answer the following question given this paragraph: Tuberculosis (TB) is a common and often deadly disease caused by a genus of bacterium called Mycobacterium . Tuberculosis most commonly attacks the lungs but can also affect other parts of the body. TB is a chronic disease, but most people who become infected do not develop the full disease.

Choices: - E. coli - staphylococcus - streptococcus - mycobacterium A:
**Answer**
mycobacterium

Answer the following question given this paragraph: A series of chemical reactions where an initial amount of copper reacts with nitric acid, goes into solution, and disappears. Then a series of reactions proceed, only to have the copper metal recovered. The copper cycle is a good illustration of how mass is conserved in a given chemical reaction. Q: The cycle of copper reacting is a good example of what principle? Choices: - law of inertia - conservation of energy - conservation of momentum - conservation of mass A:
(A).
conservation of mass
