After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parabola.

Answers

Answer 1
Answer: Rainbow is mainly caused when light hits the tinu raindrops and reflects from the surface of those drops. The raindops actually works as a prism by separating the different bands of light that are present within the white sunlight. We continuously see the raindrops because one drop of rain is quickly replaced by another and this causes a continuous effect. The angle between the incoming light and the reflected light is 4o degrees for violet band and 42 degrees for the red band. The angle of bending is always different for different colors of light.

The human heart, composed of specialized muscle cells, beats to a specific rhythm. The heart cell rhythm partly depends on the opening and closing of series of gateways within the cell membrane, called ion channels. Some channels let certain ions flow out, others let different ions flow in. The same membrane system is at work in other cells, helping to regulate what stays and what leaves the cell.This cell membrane gateway system is specifically called the

Line Graph

Explanation:

It would be easier to see the data in a line graph. This way, you could easily see the growth of mass and the (i'm guessing height?) of the AWM in relation to the time (aka week). The bar graph could work, but a line graph would be a better option for this information.

We could possibly use water as a fuel source, rather than fossil fuels (which are limited)

Science has already developed something of the sort, and with using water as a fuel source for say vehicles and such, it's inevitable for a positive change to happen because there would be less carbon monoxide; which means less polution.
