Answer:
"The organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. So as eye. Epithelial tissue helps in protection against the microbes so as skin having different layers."
Explanation:
Eye is an organ because, the organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. Similarly, inside the eyeball there is an organ which is known as retina, with is connected with the neural and epithelial tissue which helps in detection of the light which enters into the eyeball.
Skin is an epithelial tissue because, epithelial tissue helps in protection against the microbes. Similarly skin is composed of different layers of epithelial tissue which is also supported by the layers of connective tissue, helps in protection of internal organs from damage as well as dehydration.
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

So here let's first find the amount of children every santa, in total, sees in one day. So if there are 400 santas, and each sees 125 children, you can just multiply 400 by 125 to see how many children all the Santas see in one day.
400 * 125 = 50,000
Now, since there are 30 days which all the santas see 50,000 children, you can then multiply 30 by the 50,000 children to get how many children are seen by Macy's Santas in a month.
30 * 50,000 = 1,500,000
So 1,500,000 children are seen by Macy's Santas.
