1. Photosynthesis increases oxygen levels, as oxygen is one of the remainders from photosynthesis. Remember, for photosynthesis to happen plants taken carbon dioxide and release oxygen.
2. Cellular respiration will decrease oxygen levels. For cellular respiration to occur animals take in oxygen and release carbon dioxide.
3. If there is a higher light intensity then there will be higher levels of oxygen production. Plants need energy in the form of sunlight in order to photosynthesize, and the more photosynthesis that is done the more oxygen that is produced.
If an organism has more specialized cells, it's cells because they are specialized, they have their own function.
Answer:
it can produce two types of errors or mutations. cancer occurs when mutated cells ignore or override the normal "checkpoints" regulating mitosis and begin to reproduce uncontrollably
Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.
( So basically there are 2 stages )
Answer:
dependent variable
