Miguel is studying cells in his science class. his teacher tells the class they will be examining their own cells today. she shows them how to use several scientific tools to collect a sample of cells from inside their cheeks. she explains that scientists use a certain tool to see very tiny objects like the cells from the inside of their cheeks. what scientific tool is she describing?

a) hand lens

b) microscope

c) telescope

d) video camera

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
