The figure below depicts a rabbit and a tree.
What is the best explanation for what the circles represent in the figure above?
The circles represent the cycling of energy through an ecosystem.
The circles represent the cycling of food through an ecosystem.
The circles represent that the products for respiration are the same as the products for photosynthesis
The circles represent that the reactants for respiration are the same as the products for photosynthesis.
A plant and a snail occupy the same tightly closed aquarium. The aquarium is exposed to sunlight for 12 hours a day and has 2 inches of water in it. What would happen to the snail if you removed all the plants from the snail’s environment?
The snail would die from lack of oxygen
The snail will die from lack of carbon dioxide
The snail will have higher ATP production
The snail’s mitochondrion will function better
A plants and snails occupy the same tightly closed aquarium. The aquarium is exposed to sunlight for 12 hours a day and has 2 inches of water in it. What would happen to the plant if you removed all the snails from the aquarium?
The plant would die from a lack of glucose.
The plant would die from a lack of oxygen.
The plant will thrive because it can undergo both processes of photosynthesis and cellular respiration.
The plant will thrive because it can photosynthesize but then it will die because it cannot perform cellular respiration.
The diagram below shows the cycling of cellular respiration and photosynthesis.
What are the possible effects if water (H2O) is eliminated from this cycle?
Photosynthesis and cellular respiration will continue at a normal rate.
Photosynthesis would stop and cellular respiration would continue
at a normal rate.
Photosynthesis would slow down and the rate of cellular respiration
would increase.
Photosynthesis would stop and cellular respiration would slow down and
eventually stop.
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?
Only species Y is aerobic.
Only species Y is anaerobic.
Both species X and Y are aerobic.
Both species X and Y are anaerobic.
1.A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
The ATP molecule is composed of three components. At the center is a sugar molecule, ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. What function does ATP carry out in living things?
aids in protein folding and coiling
used to capture and transfer energy
identifies DNA start sequences for transcription
.helps maintain the fluidity of cell membranes
The diagram is a food web for an ecosystem.
Which process do the animals in the food web use to convert energy from food into ATP?
cellular respiration
osmosis
photosynthesis
transcription
Which of the following equations represents the overall chemical reaction for photosynthesis?

6CO2+ 6H2O→ C6H12O6+ 6O2
6O2 + 6H2O→ C6H12O6 + 6CO2
