gas exchange is a primary example of simple diffusion,the exchange of *oxygen* and *carbon dioxide* fuels the cellular processes such as photosynthesis and cellular respiration
We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms.
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:
1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.
2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.
3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.
Hope this helps!</span>
Answer:
The correct answer choice is B
Explanation:
We use these brackets in the first place to show the main molecule interconnection with other appendage molecules. For example, Ca(OH)2. The main molecule of calcium is joined with other two molecules and brackets are showing interconnection simply. However, these brackets can't tell us about the orientation and position of bond in 3D space. We have to utilize stereo-chemistry for that...
