Some of the earliest research on keystone species was conducted by robert t. paine, who actually coined the term keystone species. for over 25 years paine and his students removed pisaster ochraceus, a sea star, from tidal pools on the coast of washington. throughout his research, paine discovered that removal of this predator resulted in a) another predator moving in to replace the sea stars. b) a change in trophic levels, with only producers and herbivores present. c) mussels becoming the dominant species and crowding out all competitors. d) a shift in the ecosystem and a new keystone species becoming established.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
