Answer the following question given this paragraph: The dermis is the inner layer of skin. It is made of tough connective tissue. The dermis is attached to the epidermis by fibers made of the protein collagen. The dermis is where most skin structures are located. Look again at Figure above . You'll see that the dermis has blood vessels and nerve endings. The nerve endings explain why skin can sense pain, pressure, and temperature. If you cut your skin and it bleeds, the cut has penetrated the dermis and damaged a blood vessel. The cut probably hurts as well because of the nerve endings in this skin layer. Q: What is the inner layer of skin called? Choices: - connective layer - hypodermis - the epidermis - the dermis A:
the dermis

Answer the following question given this paragraph: From the pharynx, the food moves into the esophagus. The esophagus is a long, narrow tube that passes food from the pharynx to the stomach by peristalsis. The esophagus has no other digestive functions. At the end of the esophagus, a muscle called a sphincter controls the entrance to the stomach. The sphincter opens to let food into the stomach and then closes again to prevent food from passing back into the esophagus. Q: What is the name of the muscle at the end of the esophagus? Choices: - neck - intestine - throat - sphincter A:
(Answer)
sphincter

Answer the following question given this paragraph: Some elements have been known for centuries (gold, silver, iron, copper, among others) while others have been created in the lab only within the last several years. Most elements do not exist as such in nature. They are so reactive that they can be found only in combination with other materials. Q: What is the term for the process in which water vapor changes to tiny droplets of liquid water? Choices: - dispersion - vaporization - diffusion - condensation A:
(A).
condensation

Q: Electrical messages are carried by chemicals called what? Choices: - receptors - amino acids - Biotoxins - neurotransmitters A:

Ans:neurotransmitters
Ques:Answer the following question given this paragraph: Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal conductors are materials that are good conductors of thermal energy. Thermal insulators are materials that are poor conductors of thermal energy. Both conductors and insulators have important uses. Q: What is the transfer of thermal energy between particles of matter that are touching called? Choices: - convection - activation - radiation - conduction A:

Ans:
conduction
