Correct answer: A). Gathering evidence
The scientific explanation uses measurements and observations in order to explain something in the natural world. The Scientist uses the scientific method to collect evidence in the experiment that is related to the hypothesis.
They can gather the evidence by just observing the natural world and its phenomena or by performing an experiment in the laboratory or by running a model.
Hence, the correct answer would be option A.
I might be wrong but i think is C
The hormone is ANTIDURETIC HORMONE, ADH.
The collecting duct and the distal convoluted tubules vary in their permeability to water based on the quantity of ADH present. The collecting duct becomes more permeable to water when the ADH production increases. As the ADH production decrease, the urine volume increases. <span />
1. Three nucleotide bases on mRNA (which are complementary to three nucleotide bases on DNA) are called codon. Each codon codes for the specific amino acid. So, for 1 amino acid in protein, there are 3 nucleotides on RNA (or DNA). That is why the coding sequence is three times as long as the <span>protein sequence it codes for.
2. There are 20 different amino acids, but there are more than 20 combinations of three nucleotide bases on DNA. There are 64 different combinations of three nucleotide bases on DNA, which is about 3 times more than the number of amino acids. So, different combinations of three nucleotide bases code for one amino acid and this is the reason why </span>the DNA sequence is so <span>different when the protein sequence isn’t</span>
