Which are examples of science rather than pseudoscience? Check all that apply. People can get rid of hiccups by holding their breath. The US surgeon general's 1964 report declared that smoking cigarettes was linked to cancer. Going outside with wet hair will cause a person to catch a cold. The average global temperature of the Earth has increased by almost two degrees in the last century. People should not swim right after eating because they could develop severe muscle cramps and drown.

1. People can get rid of hiccups by holding their breath 2. Going outside with wet hair will cause a cold  3. People should not swim right after eating

Explanation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
