Mathematical Operations with Negative and Positive Numbers
Evaluate the following equation: 2*3-1
5
What is the missing number that makes the following equation true: 2*"____" =4
2
Where do consumers get the sugar they need to do cellular respiration?
From the food they eat
Carbon Dioxide (CO2) and water (H2O)
Where do consumers get the matter and energy they need to live, grow, and reproduce?
From the other organisms they consume
Evaluate the following equation:
(-1)*2
-2
What is the missing number that makes the following equation true: 5+"____"=16
11
Where do consumers get the oxygen gas (O2) they need to do cellular respiration?
From the air (or water) around them, often times through breathing
What happens to the carbon dioxide produced during cellular respiration?
It is released back into our blood stream and then we breathe most of it out
Is sugar a type of fat, carbohydrate, or protein?
Carbohydrate
Evaluate the following equation: (-4)+(-5)
-9
What is the missing number that makes the following equation true:
50 - "_____"=20
30
Which molecule has the stored chemical energy in it?
The glucose sugar (C6H12O6)
What stays in the cell after cellular respiration takes place?
The released from breaking down the glucose molecule
What is fat?
Oils that provide long-term energy storage and help us absorb certain important vitamins
Evaluate the following equation: (-2)*3-(-1)
-5
What is the missing number that makes the following equation true:
30 div "_____" = 3
10
Mitochondria
What does our body do with the energy it gets from cellular respiration?
Energy to move, grow, think, and continue doing other important body processes
What are proteins?
Molecules that make up much of our body structures and help out body function
Evaluate the following equation: -5+10div(-0.1)
-105
What is the missing number that makes the following equation true:
2*"_____" -5=5
5
How many oxygen gas molecules (O2) are needed to break down one glucose molecule (C6H12O6)?
6
How do photosynthesis and cellular respiration cycle matter and energy through ecosystems?
Photosynthesis turns the suns energy into chemical energy that can be used by living organisms. They do this by converting carbon, oxygen, and hydrogen atoms from carbon dioxide and water into glucose and oxygen gas. These molecules are turned back into carbon dioxide and water when the energy is released from the glucose to be used by an organism through cellular respiration.
Photosynthesis and cellular respiration chemical equations are the reverses of each other
What is the most common molecule in the human body?
Water (H2O) makes up over half of the average human body.
