In 1900 more than 30 percent of deaths in the u. still were caused by infectious disease. in 2005 what percent of deaths were caused by infectious disease?

a. more than 30%
b.30%
c. less than 5%
d.0%

option c is the correct answer.

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.
