AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

2. Biological Classification Classification The process of grouping living organisms into convenient categories based on simple characters is known as classification. 1. Two kingdom classification Carolus Linnaeus divided all living things into two kingdoms- Plantae and Animalia. 2. Five kingdom classification R.H. Whittaker divided all living things into five kingdoms- Monera‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The main criteria for classification included o cell structure o thallus

horrific and fatal. Those exposed to the nerve agent can die within 15 minutes of exposure. Mr. Obama’s absolutist position against it is backed up by international law and the United Nations. The 1925 Geneva Protocol prohibits the use of chemical and biological weapons in war. this was reinforced by the 1997 Chemical Weapons Convention‚ which aimed to eliminate an entire category of weapons of mass destruction‚ and forced countries involved to destroy all of their production facilities. Only five of the

During my senior year of high school I applied to Millersville University to pursue a Bachelor of Science in Biology‚ with a concentration in marine biology. Through my undergraduate studies‚ my interest in biological oceanography developed. There are many overlapping aspects of biological oceanography and marine biology that interest me and why I want to pursue a graduate degree in this field. I am particularly interested in marine phytoplankton‚ their role in primary productivity‚ harmful algal

Stem Cell Research Adult stem cell research is providing opportunities to treat people with a various diseases and conditions. In 2010‚ a man’s ankle refused to heal so the doctor took bone marrow from the man’s pelvic bone with a needle‚ condensed it to about four teaspoons of rich red liquid‚ and injected that into his ankle. Four months later‚ the ankle was healed! Adult stem cells are found in all tissues of the growing human being and‚ according to latest reports‚ also have the potential

The use of biological agents in bioterrorism is a topic that generates strong reactions and many opinions. While the use of these agents is not new‚ the increasing level of use in wartime situations is becoming more of a reality. Because biological agents can be relatively cheap to manufacture and can be easily hidden until time to use‚ they have become a real threat to our world. It is important to understand the history of this form of warfare and identify the most widely used agents so that

Although terrorists could use many disease-causing agents‚ experts on biological warfare regard anthrax and smallpox as the two biggest hazards. Other infectious diseases that pose a threat include plague‚ tularemia‚ botulism and tuberculosis. However‚ experts believe these organisms and diseases are unlikely to cause widespread

as terrorizing as biological weapons. Biological weapons are much harder to detect and protect against than ordinary terrorist attacks. Anthrax is a biological weapon that makes people so sick that it can kill them within a short amount of time if they do not get proper medical treatment in time. The fact that anyone would want to deliberately infect other individuals with deadly virus or diseases is entirely disgusting and sick. The first line of defense against biological weapons like anthrax

system which Carl Linnaeus devised in the 17th century has proved to be very useful in the field of taxonomy and for the taxonomists of today. Before the Linnaean system of classification was introduced (which falls under the classification of biological/natural classification)‚ artificial classification methods were the most significant ways of identifying an organism. Artificial classification was the system in which early scientists would use only one characteristic or feature to classify a

In the end the people got their antidote and it was a happy ending‚ I think even though many people died just because of this biological weapon. This movie just shows the capability of the military and certain individuals to fight against odds. They pushed their limits just to cover up their mess and others to save their love ones.
