Answer the following question given this paragraph: No doubt you already have a good idea of what temperature is. You might say that it's how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler. Q: In physics, what is defined as the average kinetic energy of the particles of matter? Choices: - density - friction - magnetism - temperature A:
temperature

Answer the following question given this paragraph: Sebaceous glands are commonly called oil glands. They produce an oily substance called sebum. Sebum is secreted into hair follicles. Then it makes its way along the hair shaft to the surface of the skin. Sebum waterproofs the hair and skin and helps prevent them from drying out. Q: What oily substance prevents the hair and skin of living things from drying out? Choices: - pus - progesterone - pancreatic enzymes - sebum A:
(Answer)
sebum
Ques: Answer the following question given this paragraph: The cells of all protists have a nucleus. They also have other membrane-bound organelles. For example, all of them have mitochondria, and some of them have chloroplasts. Q: The cells of all protists have a what? Choices: - argon - cell walls - protons - nucleus A:
Ans: nucleus
(Q).
Answer the following question given this paragraph: Fungi are simple eukaryotic organisms that consist of one or more cells. They include mushrooms and yeasts. Human diseases caused by fungi include ringworm and athlete's foot. Both are skin diseases that are not usually serious. A ringworm infection is pictured below ( Figure below ). A more serious fungus disease is histoplasmosis. It is a lung infection. Though fungal infections can be annoying, they are rarely as serious or deadly as bacterial or viral infections. Q: Ringworm and athlete's foot are human diseases caused by what simple organisms? Choices: - bacteria - insects - viruses - fungi A:
(A).
fungi
Ques:Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. Q: What can be used to convert the energy provided by the sun to usable electrical energy? Choices: - Wind Mills - Pannels - Power Plants - solar cells A:

Ans:solar cells
Ques:Answer the following question given this paragraph: Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards. Ball bearings are another use of rolling friction. You can see what they look like in the Figure below . They let parts of a wheel or other machine roll rather than slide over on another. Q: What is friction that acts on objects while it is rolling over a surface called? Choices: - blowing friction - opposing friction - surface friction - rolling friction A:

Ans:
rolling friction
