Although isolated virus particles are just assemblages of chemicals‚ they consists of chemical substances of a very special kind - the proteins and nucleic acids that are the essential constituents of living matter. In viruses these substances can be studied in isolation‚ and it was such studies that led molecular biologists to some of their greatest discoveries in the 1950s and 1960s. Nucleic acids are chainlike macro-molecules that carry information for self-replication and protein synthesis. When

Viet Nam is known that is a center of world’s species diversity with a abundant natural ecosystems like: mangrove forests‚ limestones‚ seas v.v with characteristics of the tropical climates. It is a habitat and development of many endemic wild species valuable‚ some of them can’t be found anywhere else in the world. Viet Nam has many valuable wild genetic resources‚ especially medicinal plants‚ the flowers and tropical plants‚ v.v. Biodiversity in Vietnam is the great value in many different aspects

Humans‚ aliens & autism Daedalus‚ Summer 2009 by Hacking‚ Ian Contraries illumine what they are not. Aliens‚ typically from outer space‚ are almost by definition not human. Current portrayals of aliens may show more about who we‚ the humans‚ are than they do about our extragalactic contraries. In portrayal by opposites there is often a large dose of fear: for example‚ that we may be all too like the aliens we imagine. That leads to a paradox about autism and aliens. A persistent trope in some

Summer Chacon 12/15/12 Environmental Science P. 5 Ecocolumn Lab Report The purpose of an eco-column lab is to show the similarities between that and a real world. It is a useful tool for learning because you get to create and see your own little world. It is very much like the real world because of the communities of organisms that it consists of‚ along with their physical environment. An eco-column is a closed system. In a closed ecological system‚ any waste products produced by one species

7 Holt Physics Chapter 7: Rotational Motion and the Law of Gravity I. Section 7-1: Measuring Rotational Motion A. When something spins it undergoes “rotational motion”. When something spins around a single point it is called “circular motion”. B. We measure how fast something spins not in m/s (different points on the object are spinning at different velocities) but by measuring the angle described in a given time period. C. Angles can be measured in radians

Now how many of you believe in aliens? Well if you don’t‚ here are a bunch of reasons why you should believe that aliens exist. Let’s consider galaxies first. There may be 100‚000‚000 galaxies‚ because an estimated 50 billion galaxies are visible with modern telescopes. Every galaxy must have a number of stars in it‚ as many as hundreds of billions. Now we all know that stars have planetary systems. Then it is also a well known fact that the dimming and brightening of a star is when a planet crosses

Chapter 11 of Environmental Science by William and Mary Ann Cunningham begins with mentioning a case study and it’s about an endangered animal‚ they mention the owl and how that they are endangered and what they are doing to save them. The chapter then start discussing biodiversity‚ and then goes on it describes the three types‚ which are genetics‚ species and ecological. They also discussed about the threats that exists against biodiversity include habitat destruction‚ climate change and population
