A is the correct answer you are looking for
Answer:
It can be both but mainly Fresh water
The correct answer is C. Translation.
The given figure is the scheme of the gene expression. It provides the flow of genetic information from a DNA sequence to a protein synthesis inside cells. This process of flow of genetic information from DNA to RNA is called transcription and the process of flow of genetic information from RNA to protein is called translation.
Thus in given figure label A is to be replaced by transcription and label B is to replace by translation.
Catenation:
The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.
Formation of multiple bonds:
Carbon atoms are capable of forming multiple bonds with other carbon atoms.
Hydrocarbons:
All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.
isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.
