Ans.
Genetic codes provide information for the protein synthesis as each code specifically codes a particular amino acid that gets joined in polypeptide chain during the process of translation.
Each genetic code is three letter code, made up of three nitrogenous bases. There are four different bases in DNA or RNA that make sixty four codes with different combinations, out of which sixty one code for amino acids and three act as stop codons.
Thus, nitrogenous bases are important in preserving the genetic codes.
Acid precipitation is an agent of erosion weathering.
I would need the picture to know how to answer this question
Answer:
(B.) their predictions are almost never accurate
Explanation:
A model is a representation of an idea, process that scientists use in explaining a complex data to a more simple and understable way. Models reflect the natural world e.g. climate models are used by humans to learn and to know about carbon cycles, water cycles and the weather. Model do come with some limitations one of them is an incomplete detail e.g. measuring the distance round the earth, we were made to believe that the model of the Earth is spherical, so in calculating the distance round the earth certain details are missing like the variations in distance caused by valleys and mountains and other topological problems that might be encountered.
