Answer the following question given this paragraph: The lungs release carbon dioxide into the air. Carbon dioxide is a gaseous waste product of the cells. Wastes are excreted from the body by the excretory system. Therefore, the lungs are organs of the excretory system as well as the respiratory system. Q: Are the lungs organs of the excretory system, the respiratory system, or both? Choices: - excretory - respiratory - neither - both A:
both

Answer the following question given this paragraph: The thyroid gland is a large gland in the neck. Thyroid hormones increase the rate of metabolism in cells throughout the body. They control how quickly cells use energy and make proteins. Q: Hormones produced by what gland in the neck increase the rate of metabolism in cells throughout the body? Choices: - pituitary - kidney - thymus - thyroid A:
(Answer)
thyroid

Nonrenewable resources, such as fossil fuels and soil, cannot be remade or else take millions of years to remake. Q: These resources can be remade quickly, through natural processes Choices: - fossil fuel - non-renewable - electric - renewable A:
Ans: renewable
(Q).
Answer the following question given this paragraph: Glial Cells Glial cells, or neuroglia or simply glia, are the other type of cell found in nervous tissue. They are considered to be supporting cells, and many functions are directed at helping neurons complete their function for communication. The name glia comes from the Greek word that means "glue," and was coined by the German pathologist Rudolph Virchow, who wrote in 1856: "This connective substance, which is in the brain, the spinal cord, and the special sense nerves, is a kind of glue (neuroglia) in which the nervous elements are planted. " Today, research into nervous tissue has shown that there are many deeper roles that these cells play. And research may find much more about them in the future. There are six types of glial cells. Four of them are found in the CNS and two are found in the PNS. Table 12.2 outlines some common characteristics and functions. Q: What nervous tissue cells play a supporting role to neurons? Choices: - reissner cells - mammalian cells - axial cells - glial cells A:
(A).
glial cells
Ques:Answer the following question given this paragraph: Like the formation of ions, the formation of charged matter in general depends on the transfer of electrons either between two materials or within a material. Three ways this can occur are friction, conduction, and polarization. In all cases, the total charge remains the same. Electrons move, but they aren't destroyed. This is the law of conservation of charge . Q: Electrons move, but they aren't destroyed. this is the law of conservation of what? Choices: - energy - cost - matter - charge A:

Ans:charge
Ques:Answer the following question given this paragraph: Solid ionic compounds are poor conductors of electricity. The strong bonds between ions lock them into place in the crystal. However, in the liquid state, ionic compounds are good conductors of electricity. Most ionic compounds dissolve easily in water. When they dissolve, they separate into individual ions. The ions can move freely, so they are good conductors of electricity. Dissolved ionic compounds are called electrolytes. Q: In what state do ionic compounds best conduct electricity? Choices: - gas - solid - plasma - liquid A:

Ans:
liquid
