Assume that the average protein in E.coli consists of a chain of 400 amino acids. Now, a single amino acid present in the protein requires a codon to code for it. A codon consists of 3 nucleotides. This shows that a protein of length 400 amino acids will require, 400 codons to code for it, that is, 1200 (3 x 400) nucleotides are required. We know that the length of the E.coli genome on average is 5 x 
base pairs.
1200 nucleotides = 1 protein
5 x nucleotides = X no. of proteins
X = 
= 4167
The answer is 4167 proteins.
Answer: It is A
Explanation: C and D are jokes/ complete lies. B is wrong because Darwin did observe that animals and plants adapted (evolved) to suit their environments.
Answer: A. mitosis
Explanation: Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Answer:
Aerobic respiration saves a lot of energy compared to anaerobic respiration. Aerobic activities can generate up to 38 ATP per gram of glucose consumed. Anaerobic reactions only produce 2 ATP per gram of glucose.
The organelle the question is referring to is called the chloroplast. I hope this helps; have a good evening!
