A teacher makes the analogy that stem cell research did for medicine what the Internet did for communication. What is meant by this analogy?
Stem cells allow for communication between cells
Stem cell research led to a huge leap in medical science.
Stem cell research led to a setback in medical science,
Stem cell information is stored in databases online,

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
