Asexual reproduction has less genetic variety. Any catastrophic environmental change would effect all organisms. Since sexual reproduction gives a variety of genetic combinations, some organisms would probably survive.

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable. A dependent variable is the response or measure of results. Extraneous variables — other than the independent ...

10 yards are needed for a first down. With the losses, they needed to make 18 yards. They made 15. The decision to punt or go for it would depend on where they are in the field, the time remaining and the current score. They might even want to try a field goal. http://drdavesp...
