Decomposers are important because
break down dead organisms.

This image is investigating?
The relationship between photosynthesis and cellular respiration!

Fermentation takes place without oxygen present. What is the general term for this?
anaerobic respiration.
100
What do enzymes do? And what factors can influence them?
Enzymes speed up reactions and they are dependent on pH and temperature.

What is an autotroph?
An organism that makes its own food.
200
What type of relationship exists in the picture below?
Mutualism - both organisms benefit from the relationship.

If bubbles were seen coming from a plant that was exposed to light underwater in a fish tank, what gas do you think would be given off?
oxygen
200
The purpose of cellular respiration is..
To break down glucose into energy, thus releasing CO2.
200
The sharing of electrons is called this...
covalent bonding
200
Stomach acid has a pH of 3. This level is considered: acidic, neutral, or basic?
Acidic
300
What trophic level is each of these organisms in:
fox, grass, mouse, cat
Grass = Producer
Mouse = primary consumer
Cat = Secondary Consumer
Fox = Tertiary Consumer

Where does mRNA travel to once it has finished making a single strand copy of the DNA template?
A ribosome outside of the nucleus!
300
During heavy exercise, lactic acid is the result of what?
Fermentation
300
What are the products of cellular respiration?
carbon dioxide and ATP and water
300
What happens to an enzyme if the temperature increases too much?
It denatures
400
Which process usually uses carbon dioxide, sunlight, and water as reactants (inputs)?
photosynthesis.
400
What is the phosphate rich compound (pictured below) used to make energy for a cell?
ATP
400
What is needed for photosynthesis to occur?
sunlight, water, CO2
400
What's happening in this graph?
As population increases, so do carbon emissions from humans.
400
What is the purpose of having a control group in an experiment?
Control group is the one group that you will know the results to, therefore you can use it to compare the other groups to.
500
Draw a picture to show what happens during diffusion.
500
Which process involves amino acids being assembled into polypeptides and, eventually, proteins?
Translation
500
Which organelles do cellular respiration and photosynthesis occur?
mitochondria and chloroplast
500
How do unicellular organisms (prokaryotes) and multicellular organisms (eukaryotes) carry out life processes differently?
Unicellular organisms do NOT have membrane bound organelles to carry out life processes. Multicellular organisms have organelles and organ systems that carry out life processes.
