Explanation: Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
There are basically three types of evolution divergent, convergent and parallel evolution.
a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
I believe A is the most correct (i assume it's about antibiotics - they actually DO harm our immune system in some way).
B is partially correct because, the colds indeed should be treated by anti-viral medication (because the virus is a cause of typical cold) but using antibiotics during recovery is needed only when an additional bacterial infection occurs as a complication after the viral infection. and it doesn't happen very often.
C - what works? antibiotics doesn't work for viral infections (colds). anti-viral medication do.
D i won't discuss.
