Answer: C) GMOs, genetically modified foods engineered in a lab to produce desirable traits.
Explanation:
The genetic engineering involves the insertion of genes from other organism to the host organism so as to make up genetically modified organism. Some unwanted and default genes are also removed from the organisms so that their body function properly.
The genetically modified foods are the examples of genetic engineering. This is done to produce desirable traits in the food crops. In plants both plants and animal genes are inserted to improve the yield of crops, and to improve their quality. In animals, the insertion of genes of other animals is likely to improve the milk and meat yield.
he Piranha is one of the most efficient predators on the face of the earth. Granted it is not a large animal, with most only reaching about 5 1/2 to 10 inches (14 – 26 cm), but it is known world wide for its ferocious nature. They have razor sharp teeth and are opportunistic carnivores.
A frenzied attack by a group of Piranha will set the water churning. They will attack and eat all sorts of aquatic animals, insects, lizards and amphibians. They will also devour rodents, carrion (dead meat), and sickly or weakened land animals that venture into the water.
The teeth of the Piranha are triangular in shape with an exact fit in their jaw, comparable to a bear-trap. They are designed to puncture and slice the flesh from their prey. They can strip their prey to the bone in a matter of minutes.
These fish are a great source of fascination. Their natural behaviors have become fodder for the scripts of moviemakers looking for a sensational twist to excite and entice an audience. What could be more intriguing than creating a 'fear factor' from the behaviors of these provocative fish found in the "wild". Yet just like the Great White Shark and the Anaconda constrictor, also popular subjects of thriller movies, the Piranha’s behaviors are over-fantasized.
The Piranha does engage in a feeding frenzy that will "make the water boil" if only because a hungry school of fish are trying to reach the same limited food source. All that activity is bound to create water turbulence. A Piranha school generally only consists of about 20 or so fish, but in a feeding frenzy it can reach up to several hundred..
Piranhas are not always that deadly. Many species live solitary lives once they reach maturity and only four or five species pose any significant danger. Piranhas rarely attack people. Many experts believe they are actually timid fish, and shoal for protection. Even the most aggressive are thought to be not really dangerous until they are trapped and confined, and then attack in self defense. As a pet they are fascinating and beautiful fish, yet you can't hold or pet them. They are not affectionate and owners must be extremely careful, especially when handling them. They do have sharp teeth and an aggressive/defensive nature. Most Piranha bites are sustained when the fish are being handled, though that's not to say a hungry fish is never dangerous.
The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.
Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.
Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.
The kingdom of fungi is made up of variety of organisms, such as mushrooms, yeast, molds, etc. The organisms in this kingdom live by decomposing and absorbing the organic molecules on which they grow.
The major characteristics of the organisms in the fungi kingdom is that they possess hyphae, which they use for absorption of nutrients.
The organisms in the fungi kingdom are multi cellular eukaryortic and are incapable of producing their own food, that is, they are heterotrophs.
Take for example the group of prokaryotes against eukaryotes. They may be similar in a way that they contain cells with organelles such as mitochondria, ribosomes, cytoplasm, and many more. But they may differ in the presence of a cell membrane and a nucleus. Eukaryotes have cell walls and a nucleus, while prokaryotes don't have.
