Answer:
A. All organisms have a common biochemical evolutionary origin.
Explanation:
Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid. 
One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

Answer:
Daphnia is an ideal system for studying multiple stressors because of its short generation time, well-studied ecology and evolutionary history, wide geographical distribution across many limnetic systems, high mutation and recombination rates, high sensitivity to changes in environmental conditions, unique cyclical
