When a woman that is 9 months pregnant receives the message to release the hormone oxytocin into the bloodstream, and then as a result the hormone causes her cervix to dilate, which then results in the release of more oxytocin.

Name three ways that carbon dioxide gets into the atmosphere

Burning fossil fuels for

1. electricity

What has been happening to the concentrations of greenhouse gases in Earth's atmosphere over the past 200 years?
It has been increasing.
400

Clearcutting to make room for an outlet mall.

Deforestation

Blood sugar increases and the pancreas releases insulin, liver removes glucose from blood and stores it as glycogen, blood sugar is set back to normal level.

Negative feedback loop
400

This causes increased precipitation which results in flash flooding.

Describe albedo effect.

Albedo is the amount of light and heat reflected. Ice and snow have high albedo and ocean and land have low albedo and result in more absorption of heat and light.
