... it. Another example of the importance of the center of gravity is how an airplane flies. If the center of gravity is too far forward, the plane will have an unstable equilibrium and in turn will take a nose dive into the ground. If the center of gravity is too far aft (back) the plane will fall out of control. You must limit the weight and its positioning on board the aircraft to prevent these occurrences from happening. The engineers design an airplane so that it has a maximum weight capacity of passengers, cargo, fuel, and etc... The engineers design an airplane so that the center of gravity must stay within certain limits. Any weight added to an airplane may ch ...
... zero. Temperatures in cryobiology range from zero degrees Celsius--water freezes--to just above negative two hundred and seventy three point sixteen degrees Celsius--absolute zero. The word "Cryogenics" comes from the Greek word “kryos” meaning cold (“Cryogenics” Raintree 127, Kavaler 16). The science of cryobiology was first recognized in the early nineteen sixties. Cryobiology is the study of the effects of extremely low temperatures on living animals and plants. The chief concern in cryobiology is to preserve living matter for future use. This method can also be called cryopreservation. Cryotherapy is the use of extreme cold in treatment. The f ...
... date palm. The writers of this article however have been testing halophytes, which, is a salt-tolerant plant that can be used for food, forage and oilseed crops. They first gathered several hundred halophytes and began testing these plants in the desert of Puerto Peñasco. They irrigated the plants daily by flooding the fields with seawater from the Gulf of California. The best halophytes produced roughly the yield of alfalfa using freshwater irrigation. In order to show that these halophytes could replace other crops for use they tested to see if the crops could feed livestock. The halophytes have protein and carbohydrates but they contain too much salt. Thi ...
... meals. Small amounts of carbohydrates are also used for structural purposes and others are attached to outer surfaces of cell membranes to guide cellular interactions. For many cells, sugars are the most important source of energy. Lipids are important because they function as structural components of cell membranes, sources of insulation, and a mean of energy storage. The lipid molecules are most well known as forming basic structures of cell membranes and as energy storage molecules as well. In this group of lipids, there are about three main types: true fats (triglycerides), phospholipids, and steroids. True fats represent the body’s most abundant and ...
... a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point be ...
... sometimes be difficult to distinguish whether or not someone has been exposed to the other form of , genital . This is because there are very often no symptoms that go along with the virus. This is not always the case though and when symptoms do occur they are often seen as a cluster of blister sores, usually on the vagina, vulva, cervix, penis, or anus. For genital , symptoms may last several weeks, go away but only to return again weeks, months, or even years later. Symptoms may also include pain in the infected area, itching, burning feeling if urine flows over sores, and possibly an inability to urinate if severely swollen from many sores. Very severe outbr ...
... times, dogs have been domesticated by humans and it has helped him to hunt, in herding, protection, etc. It has been very important as a work animal and as a psychological support for humans. The habitat of the dog is where it’s owner lives. Different dogs have different adaptations to their ancestral habitat but nowadays, this is not applicable. ANATOMY SKELETON The skeleton of the dog is the articulated structure, moved by the muscles, that holds the dog’s body and protects some organs and the nervous system. It also functions as mineral and blood deposit of the body. The skeleton of a dog is made up of approximately 321 bones: 134 form the axial skeleton ...
... 12 feet. 2. Bonnethead (Spyrna tiburo)-With a head shaped like a shovel the bonnethead rarely grows more than four feet long. This shark is commonly seen inshore. 3. Smooth hammerhead (Sphyrna zygaena)-Bronze with dusky fin tips, it can grow to thirteen feet. 4. Great hammerhead (Sphyrna mokarran)-Attaining a length of a possible 18 feet, this is the largest and most dangerous of all the hammerheads. One of the most interesting things about the hammerheads is the unique shape of their heads. Ever since scientists started to study the hammerhead they have speculated about the use of the hammer. The hammer is a complex structure and probably serves more th ...
... more true than in nature, where dozens of animals (and plants) spend their time masquerading as others. So clever are their disguises that you've probably never known you were being fooled by spiders impersonating ants, squirrels that look like shrews, worms copying sea anemones, and roaches imitating ladybugs. There are even animals that look like themselves, which can also be a form of impersonation. The phenomenon of mimicry, as it's called by biologists, was first noted in the mid-1800s by an English naturalist, Henry W. Bates. Watching butterflies in the forests of Brazil, Bates discovered that many members of the Peridae butterfly family did not look ...
... administrations due to pressure from the pro-life factions of the Republican party.” The societal issue addressed is expressed from all point of views, and the following will further strengthen and help you understand their points. “The procedures used in human embryo cloning have been around for many years, and have been used in the cloning of cattle and sheep embryos, for the production of animals with known genetic traits. The news of human embryo cloning did not surprise many people in the scientific community, but it shocked the general public.”(psu.edu) Many biologists believe that they have a personal duty to the improvement of society ...
