The Praying Mantis

.... The Mantidae family, in turn, is part of the order/suborder Mantodea that includes a variety of mantid-like species. But the existing literature does not reflect a clear consensus about what insect order Mantodea belong in. Some have placed Mantodea in the Dictyoptera Order-with the roaches. Others place Mantodea in the Orthoptera Order-with crickets and grasshoppers. Finally, some believe that Mantodea constitute their own independent order of insects.

Predator - Prey Relationships

.... and the predator derives nourishment from the prey on which it feeds(Nitecki 1983). Parasitism is different from most normal predator prey situations because many different parasites can feed off of just one host but very few predators can feed on the same prey(1973). In parasite-host relationships most commonly the parasite is smaller than the host. This would explain why many parasites can feed off of one single host. Another difference in parasite-host relationships is that normally the parasite or group of parasites do not kill the host from feeding, whereas a predator will kill it’ s prey(1983). Efficient parasites wil .....

One of the methods used for this purification process was using .....

Properties Of Water

.... also has a very high heat of vaporization. Converting one gram of cold water into ice requires 80 Calories of energy. Converting the same amount of very hot water into steam requires 540. The high amounts of energy required to change water from its liquid state make water tend to stay a fluid. The process of freezing water involves slowing down the activity of the water molecules until they contract and enter into a solid state. Once the ice is cooled down to 4 degrees or less, the hydrogen bonds no longer contract, but they become rigid and open, and the ice becomes less dense. Because the ice has become l .....

Acid Rain

.... as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one. This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. .....

Mitochondria

.... and related processes to produce the ATP required to perform cellular work.(Campbell 182-9) Pyruvate, or fatty acids from the breakdown of triglycerides or phospholipids, pass easily through pores in the outer mitochondrial membrane made up of a channel protein called porin. The inner membrane is a more significant barrier and specific transport proteins exist to carry pyruvate and fatty acids into the matrix. Once inside the matrix, pyruvate and fatty acids are converted to the two carbon compound acetyl coenzyme A (acetyl CoA). For pyruvate this involves a decarboxylation step which removes one of the three carbons of pyruva .....

Sharks

.... yet, it could have been the overall storyline: A Great White shark with an eating disorder and a taste for human flesh. Perhaps that’s what is keeping vacationers from grabbing their trousers and snorkels. Over all, there have been 1026 attacks on humans by sharks in the last ten years. Only 294 of these attacks have been linked to Great White sharks. That’s roughly the number of people who drown each year in swimming accidents. Of these 294 attacks, less than eighteen percent were fatal. Out of the eighteen fatal incidents more than seventy percent was contributed to loss of blood.

Near Earth Objects

.... collisional fragments and burned-out short-period comets. According to Dr. Tom Gehrels of the University of Arizona Spacewatch program, "The total number of NEOs over 100 meters is estimated to be about 100,000, with 150 or so currently known". Do they pose any real threat to Earth? The Earth orbits the Sun in sort of a cosmic shooting gallery, subject to impacts from asteroids. It is only fairly recent that we have come to appreciate that these impacts by asteroids pose a significant hazard to life and property. Although the annual probability of the Earth being struck by a large asteroid is extremely small, the conseque .....
