That'll be guanine. If you look up "pyrimidine" in google, it will tell you the two nucleotides that are pyrmidines are cytosine and thymine. So that leaves guanine.

stromatolites
Explanation:
"stromatolites is a calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australasia"
Ancient cyanobacteria present in stromatolites are considered as key factor for the increased amount of oxygen in atmosphere. Furthermore, these were considered as first organisms to trap carbon dioxide and release oxygen by the process of photosynthesis.
I would say the the mechanism of control and co-ordination in plants and animals is called the Hormonal Feedback Mechanism. Since hormones command many cell functions, they are very important for homeostasis. Hormones control many cell activities, so they are very important for homeostasis or the stable functioning of an organism. These hormones are managed by feedback mechanisms. Such a mechanism feeds back to control its own production. It does this in a continuous loop.
Answer:
space
Explanation:
space is our solar system therefore water is found in space, and on earth, and on many other planets.
<span>This energy gets trapped in the ATP as it converts from ADP to ATP by the addition of phosphate. There are 3 main pathways for harvesting energy from glucose: Glycolysis - begins glucose metabolism in all cells to produce 2 molecules of pyruvate. Occurs outside of mitochondria, usually in cytoplasm</span>
