Moves Oxygen into the body and Carbon dioxide and water out of the body
100
what is the difference between repiration and breathing?
breathing is a physical movement of your rib muscles and diaphragm expanding to let air in and out
respiration is a chemical process in the cells mitochondria that combines oxygen and glucose to release energy
100
What is th dark, sticky substance that forms when tobacco burns
Tar
100
What are 2 main differences between a plant and animal cell
What is a cell wall and chlorophyll
(plants also have larger vacuoles)
100
An experiment where only 1 variable is changed
What is a controlled experiment
200
What are the components of the respiratory system?
Nose, Trachea,
Bronchi, Lungs , Alveoli
200
What are is the waste product given off by respiration?
carbon dioxide and water
200
What is the dangerous chemical / drug found in tobacco that causes addiction, increased heart rate, and an increase in blood pressure
What is nicotine
200
An organism that consumes both plants and animals
What is an omnivore
200
In a controlled experiment, the variable that is changed by the scientist (you can only have 1 or the results will be invalid)
What is the manipulated variable
300
the raw materials needed for respiration
What is glucose and oxygen
300
Why do you breathe faster when you exercise?
Your muscles are burning glucose faster for energy and need more oxygen and need to get rid of the carbon dioxide being given off after respiration
300
A poisonous gas that is found when tobacco is burned---it also come out of a car's tailpipe as exhaust
What is carbon monoxide
300
the process where autotrophs take in carbon dioxide and water and with energy from sunlight produce thier own food- glucose
They then give off oxygen
What is photosynthesis
300
How will increasing the temperature of water effect the rate at which it melts?
What is the Manipulated variable?
What is " increasing the temperature"
400
The muscle that expands the rib cage so you inhale
What is diaphragm
400
What are the passageways that lead to the lungs called?
Trachea & Bronchi/Bronchus tubes
400
a serious disease that destroys lung tissue and causes breathing difficulties because they don't get enough oxygen - the damage cannot be healed by stopping smoking
What is emphysema
400
A relationship where one species benefits and another is harmed
What is parasitism
Parasite: benefits
Host: is harmed
400
The variable(s) that are measued and observed to see how the change in the manipulated variable effected this variable
What is the responding variable
500
How does oxygen enter the red blood cells to be taken to the cells of the body?
Oxygen enters the alveoli, tiny air sacs, inthe lungs and then is taken to all the cells of the body where it is combined with glucose to release energy in cellular respiration
500
What process in the alveoli allow the two gases, carbon dioxide and oxygen, to pass through the membrane?
Diffusion!
500
when people involuntarily inhale the harmful chemicals in a cigarette,cigar, or pipe.
This cause asthma, bronchitis, cancer, and other respiratory diseases
What is passive or second hand smoke
500
A process by which individuals that are better adapted to their environment are more likely to survive and reproduce than others of the same species
** pass on adaptations that occur (think turtles on the Galapogos Islands)
What is Natural Selection
500
A scientist wants to make sure the results of his experiment are valid. The results are caused by the manipulated variables effect on the responding variable. He has to make sure of what 2 things.....
There is only 1 manipulated variable and all other factors are controlled variables
