Answer the following question given this paragraph: An inclined plane is also a simple machine. The resistance is the weight of the box resting on the inclined plane. In order to lift this box straight up, the effort force would need to be equal to its weight. However, assuming no friction, less effort (a smaller effort force) is required to slide the box up the incline. We know this intuitively; when movng boxes into a truck or onto a platform, we use angled platforms instead of lifting it straight up. Q: An inclined plane is a good example of what kind of machine? Choices: - strong - complex - weak - simple A:
simple

Answer the following question given this paragraph: With the naked eye, bacteria just look like a slimy smear on a petri dish. How can we study them in more detail? The invention of the microscope has allowed us to see bacteria, cells, and other things too small to be seen with the naked eye. Q: How does the bacteria look when seen with the naked eye? Choices: - slippery smear - dry smear - oily smear - slimy smear A:
(Answer)
slimy smear
Ques: Answer the following question given this paragraph: Movable joints are also known as synovial joints. This is because the space between the bones is filled with a thick fluid, called synovial fluid, that cushions the joint (see Figure below ). Q: What is the thick fluid in the space between bones that cushions the joint? Choices: - interstitial fluid - amniotic fluid - collagen - synovial fluid A:
Ans: synovial fluid

Answer the following question given this paragraph: Strontium is a silver-colored alkaline Earth metal that is even softer than calcium. Strontium compounds are quite common and have a variety of usesfrom fireworks to cement to toothpaste. In fireworks, strontium compounds produce deep red explosions. In toothpaste, like the one pictured in the Figure below , the compound strontium chloride reduces tooth sensitivity. Q: What is a silver-colored alkaline earth metal that is even softer than calcium? Choices: - mercury - magnesium - lithium - strontium A:
(A).
strontium
