C...the key is that they are photosynthetic...so they produce oxygen (like plants)!
Answer:
DNA sequences.
Explanation:
DNA sequences, I believe, are the best evidence of common ancestry since they share more traits with more closely related organisms. The similarities and variances in fossils, anatomy, and embryos are all due to DNA.
Answer:
Unable to be divided into further smaller pieces
Explanation:
This theory has been drawbacked by now but books still obey it.
Atoms can be divided further more into proton, neutron and electrons
The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.
