The theory of evolution proposed that a series of catastrophes or mass extinctions followed by repopulation could explain why species change over time
Answer:
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
Answer:
The answer is 6.4 ×
Joules
Explanation:
This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:
Force = 8.0 pN = 8.0 ×
N
displacement = 8.0 nm = 8.0 ×
N
Now let us calculate the work.
work = Force × Displacement
work = 8.0 ×
× 8.0 ×
= 64 × 
= 6.4 ×
Joules (in standard form)
