Effect Of Temp On Endo And Ectotherms (metabolism)

... rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996). Metabolic rate is directly linked to the core temperature in an animal. An ectotherm, or cold blooded animal, warms its body mainly by absorbing heat from its surroundings. The amount of heat it derives from its metabolism is negligible. In contrast, endotherms derive most or all of its body heat from its own metabolism (Campbells,p899). Because ectotherms do not produce their own heat, they cannot actively ensure their ideal temp ...

Marijuana 2

... a sticky black liquid called hash oil. There are three distinct species of cannabis: Cannabis sativa, Cannabis indica, and Cannabis ruderalis, though there is some argument as to whether these should be considered varieties rather than species. Most recreationally used cannabis is the result of interbreeding between these three types. The term 'hemp' is generally used to describe low-thc varieties of cannabis, which are grown for industrial uses. The strength of cannabis varies greatly from one variety to another.

Reproduction: A Courting To Nature

... It was, rather, for another - for her preening rival across the Bavarian lake. Poor goose. Will she mate with the gander of her dreams? Or will she trail him for years, laying infertile egg clutches as proof of her faithfulness? Either outcome is possible in an animal world marked daily by scenes of courtship, spurning and love triumphant. And take note: these are not the imaginings of some Disney screen-16 writer. Decades ago Konrad Lorenz, a famed Austrian naturalist, made detailed studies of Greylags and afterwards showed no hesitat ...

The Destruction Of The Ozone Layer

... is really disappearing, we need to understand what it is and what it does. When ultraviolet light from the sun hits the earth's atmosphere, it hits and divides the oxygen molecule (O2). Each molecule then attaches with other oxygen molecules to form O3. O3 is ozone. So when ozone is formed, harmful rays from the sun are absorbed. The O3 molecule is very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So ...
