Answer:
This is a slightly vague question because there are many reasons why DNA can be damaged and determining which organelle was at fault is generally a case by case matter. but the only part of a cell that you could considered to be tasked with protecting genetic material is the nuclear envelope which is simply a phospholipid bilayer surrounding the nucleus and/or the nucleolus so I would say the answer is the nuclear membrane and/or nuclear envelope.
Fractional distillation is the process in which the alkanes in petroleum can be partly separated. This is due to the petroleum having different boiling points. The process starts off with the heating of crude oil for it to vaporize. The vaporized crude oil is then fed into the bottom of the distillation tower. The resulting vapor rises through a vertical column. As the gases rises through the distillation tower, its temperature decreases. Thus, certain hydrocarbons begin to condense and run off at varying levels. Each level-specific condensed fraction contains hydrocarbon molecules that has a similar number of carbon atoms. These "cuts" of boiling point allow numerous hydrocarbons to be separated out in a single process. The cooling of the tower height allows for the separation. Subsequent to the refinement, individual fuels may undergo more refinement to remove existing contaminants or substances so as to improve the quality of the fuel through cracking.
Answer:
some genes can funtion on their own
Explanation:
Muscles are named according to their size, location, function, origin or insertion point. The location of muscles are named on the bases of their size and location such as sternocleidomastoid which is named after its origin ( on ster-num and clavicle) and insertion ( mastoid process).
Naming of the muscles after its function that allows a person to move speak and chew , they can control heartbeat , breathing and digestion.Skeletal muscles are attached to bones and helps in its movement , and perform involuntary function and cardiac contractions.
There are more than 650 muscles in human body such as smooth muscle, they perform variety of vital function.
