Given -The average gallon of gas contains about 5 lbs. of carbon.
-One five-pound bag of charcoal briquettes contains approximately 100 briquettes.
-5 lbs. of carbon/100 briquettes = 0.05 lbs. carbon per briquette
* Sample Problems
1. If you drive or ride in a vehicle that averages 25 mpg, how many briquettes per mile would you be emitting?
2. If each briquette contains 0.05 lbs. of carbon, how many lbs. of carbon are emitted each mile?

the correct answer should be false

{apex}

i think that it is plants

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.
