Answer:
C. All of the organism’s genes are removed.
Explanation:
Mutation does not occur during DNA replication or copying process by removing all of the organism's gene. This is quite impossible.
Mutation is term registered in genetics. They are the changes that occurs to genes when being copied or sometimes as a result of imparting environmental factors like exposures to ultraviolet radiation.
- Genes can mutate when sections are mistakenly removed or added.
- Also, when entire gene is reversed, genes can mutate too.
Genes do not mutate by removing all of them. It is biologically inconsistent.
Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
Antarctic soils exist, in general, they comprise a surface pavement (i.e., a layer of gravel, stones or boulders formed largely by weathering and the removal of fine materials mainly by wind action) and a seasonally thawed active layer over permafrost.
