Answer:
Cytosine- 40%
Explanation:
DNA is the genetic material in virtually all living organisms. It is a molecule made up of long chains of nucleotides, which are its building block. Four types of nucleotides make up the DNA molecule viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
According to Erwin Chargaff in his rule regarding DNA composition, he stated that in a DNA molecule, the amount of adenine must equal thymine while that of guanine must equal cytosine. In a nutshell, the total of all the base pair must equally be 100% i.e. (A + T) + (G + C) = 100%.
In this case where a newly discovered bacteria from a hot spring in Yellowstone National Park was found to contain 10% of adenine in its DNA. Since Adenine is 10%, Thymine base must also be 10% in accordance to Chargaff's rule.
Hence, 10% + 10% + (G + C) = 100%.
20% + G + C = 100%
G + C = 100 - 20
G + C = 80%
Since, G and C must be equal, then G = C = 80% ÷ 2 = 40%. This means that the percentage of cytosine will be 40%.

Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.
Answer:
Proteins can be catalysts which help to reduce the energy used in a chemical reaction or speed it up. Proteins can help carry oxygen throughout the body in the form of hemoglobin

Hello LonelyPerson, to answer your question.
The Galápagos were officially annexed by Ecuador in February 12 1832 and were named "Archipelago del Ecuador.". It is still today officially a province of Ecuador. Ecuador claimed the <span>Galápagos Islands</span> just three years before their most famous visitor, Charles Darwin, dropped anchor on the Beagle and stepped ashore and into history.
