Answer: The simplest way is to determine if a strain is mutant is observing morphology, growth rate, double time, etc but it is accurate if you can prove if the strain is deficient in one aminoacid or can't metabolize lactose, etc.
Explanation: A wildtype strain functions normally, for example, can metabolize as a carbon source, glucose, lactose and other sugars, can synthesize all the aminoacids requered for protein synthesis, etc. If a strain suffers a mutation and it is inheritable, the strain become a mutant. Since several mutations can be silent ones, only those that interfere with a process, can be assesed easyly.
For example, if you have several strains and put them in a lactose medium, but some of them cannot growth means that are lactose mutants. Those strains could carry a mutation in genes that encode lactose degrading enzymes or in regulatory genes of the lac operon, etc.
In the Claritin commercial, the man is laying in the grass with a
beagle puppy. The beagle is a breed of small hound that is similar to a larger
foxhound that has approximately
220 million scent receptors. This is the reason why they are employed as
detection dog and not as guard dogs for they are usually friendly dogs.
Presumably whatever their nutrition and health requires, for instance, if a tree frog requires fruit flies to maintain a healthy and balanced diet, then the conservation center probably feeds their tree frogs fruit flies.
<span>Evolution can best be summed up by statement D - change in a population through genetic variation over time. The other statements do not refer to evolutionary changes, as these are changes that occur slowly, rather than suddely or with speed.</span>
