The cane toad was a failure as a biological control method in Australia because: -The greyback beetle it was supposed to be eating fed at the top of the sugarcane stalks (which were 6-8 meters in height). Cane toads cannot fly or climb and therefore couldnt feed on the beetles. -The beetles were out during the daytime, and cane toads feed at night. -The two species are not seasonally compatible (aren't in the same place at the same time of year). -The toads needed moist conditions to survive, and so moved away from where they were supposed to be. -The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives. -Breeding habits made the cane toads a very invasive species.
the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
its actually really healthy and is quite easy once u get the hang of it. u end up eating more veggies then u might want but it really healthy and benfits you more than the meat does. ive been a vegetarian forever (never eaten meat before ever) and im athletic and everything just like any other meat eater
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
