what is the difference between the trachea and the esophagus?
The trachea is the windpipe in the respiratory system. It is the tube that carries gases to and from the mouth/nose and the lungs.
The esophagus is the pipe in the throat that carries food from the mouth to the stomach in the digestive system.
In a rainforest ecosystem, the tapir is an animal that consumes fruits and shrubs, and the ocelot cat eats the tapir as part of its diet. Earthworms break down the dead matter.
Create the food chain for this example showing the flow of energy with arrows.
fruit and shrubs - tapir - ocelot cat - all give energy to earthworms
What is the law conservation of mass?
mass cannot be created nor destroyed, only transformed
explain in detail the difference between warm front and a cold front.
A cold air mass pushes the warm air mass up and out of the way - low air pressure, brings thunderstorms and lower temperatures
Warm Front = when a warm air mass slides up over a cooler air mass. - brings low air pressure, light/steady rain, higher temperatures
On a time and distance graph, explain what a flat line, steep line, flatter line, and downwards line mean.
steeper - faster
flatter - slower
flat - at rest
down - return back to where it started
