Answer:
Explanation:
According to Erwin Chargff's rule, he stated that, adenine (a purine) always forms base pairs with thymine (a pyrimidine) and that guanine (a purine) always forms base pairs with cytosine (a pyrimidine). an adenine does not form base pairs with cytosine despite it being a pyrimidine.
thus the amount of adenine will always be equal to that of thymine while
the amount of guanine will always be equal to that of cytosine. Therefore, since we have 22% of adenine, the amount of thymine will also be 22% making a total of 44%. thus to find the amount of guanine and cytosine = 100-44= 56%.
the amount of guanine will thus be 56/2= 28%, since guanine and cytosine are of equal amount.
Answer:
The correct option is 'c'
The archaea and bacteria diverge from early eukarya.
Explanation:
The cell wall material is different from archaea with bacteria as the cell wall of archaea lack peptidoglycan and contain lipid and hydrocarbons rather than fatty acid but the cell wall of bacteria contain peptidoglycans.
Archaea and bacteria both derived from eukarya as they both have similarities with eukarya.
The similarity between archaea and bacteria is that they both share lateral gene transfer.
There are similar features that are seen between archaea and bacteria like protein secretion,ATP production,protein modification etc.
Both bacteria and eukarya belongs to prokaryotes and the membrane of both eukarya and bacteria contain unbranched fatty acid chain that are attached to glycerol with ester bond.
Answer: Marine environments provide the perfect habitat for these seagoing birds. They can be found in tropical and subtropical regions of the west coast of Central America, and northern South America.
