Answer: The night
Explanation: 
Remember that a plant does two things, it either produces energy by photosynthesis, in which case it takes up the carbon dioxide and releases oxygen, or consumes energy to grow/carry out the functions of life.
In the second case, the plant takes the glucose, or sugar, that it made during photosynthesis and breaks it into pieces, releasing energy. This step is accompanied by the release of carbon dioxide into the atmosphere. This happens all the time, but since the plant does not produce sugar and release oxygen during the night, the night is when it produces more CO2 than O2.
 
        
             
        
        
        
Light will increase the rate of photosynthesis, should be reflected in the rate of disk rising
- no disks should rise in dark since photosynthesis requires light
        
             
        
        
        
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:
Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.
        
                    
             
        
        
        
Answer:
sedimentary rocks
Explanation:
 can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.
