Heat Transfer
conduction, convection, radiation
What is yes, because it is unicellular
This happens to primary consumers if the population of producers declines...
What is they decline also...
The formula used to calculate speed
What is distance/time
What is 14 grams.
Why does the handle of a cast iron skillet become hot when heated on a stove
What is iron is a conductor and it is heated through conduction
Can a skin cell survive on its own?
This happens to the population of producers if the primary consumers population declines...
What is they increase because there are less consumers that consume them
What force slows/stops object
What is friction
This change occurs when a match is lit
What is a chemical change
The only type of heat transfer that does not require matter for a transfer of energy to occur.
What is radiation?
Why do multicellular organisms need transport systems?
What is to exchange gasses/and other materials with the outside environment?
What is the primary cause for destruction of ecosystems? explain
What is humans via deforestation, pollution, over-hunting, etc
This force causes a pencil to roll off a desk and fall to the ground
What is gravity
This change occurs when ice cream melts
This happens to metal railroad track on a hot summer day?
What system includes the femur, ribs, skull...also provide its purpose...
What is the skeletal...to provide support and protection
What is a food web is complex and a food chain is simple.
This law of motion states that an object in motion will stay in motion and an object at rest will stay at rest until an outside force acts on that object.
Example- A ball will not move unless something moves it (gravity, push, pull, etc)
What is inertia
Ferns and Orchids are found in this type of ecosystem
What is the tropical rainforest
This is heat transfer through liquids and gasses...also give one example
What is convection...hot air balloon, boiling water, steam, convection cells, etc.
Why is the circulatory system known as a transport system...explain
What is because it moves blood, oxygen, nutrients, wastes throughout the body...
What is a pond
This force causes a ball to speed up as it rolls down a ramp...
What is gravity
This is the fast moving stream of air that moves from West to East over North America...above the boundary is cold air and below is warm air
What is the jet stream
