2.The preservation of biodiversity can only be accomplished as part of an overall strategy to promote global stability.
3.Applied science is directly concerned with the application of the working laws of pure science to the practical affairs of life.
4.We are confronting an episode of species extinction greater than anything the world has experienced for the past 65 million years.
5.Our children may be able to choose their kids' traits: to select their gender and eye color, perhaps to tinker with their IQs, personalities and athletic abilities.
6.This notion rests on a dangerous lack of understanding of what goes on in an agricultural ecosystem and is one reason why biotechnology makes many people nervous.
7.Some single gene disorders are quite common and in total, diseases that can be traced to single gene defects account for about 5% of all admissions to children's hospitals.
8.Over time, scientists will piece together the genetic, physiological or ecological roots of such problems, a necessary step in building confidence in the regulatory process.
9.Concern has been voiced that biotechnology might increase the risk of biological warfare, and some have speculated that biologists today are stepping into the shoes of the nuclear physicists of 60 years ago.
10.As an example of the sensitivity of the measurement devices, the static magnetic fields produced by particles of metal in the body resulting from eating canned food were readily detected.
1l.Scientists believe that while endowing a person with various potentials, genes also set limits on what he can achieve in the future.
12.The genome refers to all the genes within a species.
13.Transgenic food, which directly changes the ecological environment, arouses questions on the safety of such food.
14.The volume of a gas becomes smaller when the pressure upon it is increased.
15.Biodiversity is the word we use to describe the variety of animal and plant species, genes and ecosystems on the planet.

19.All humans are born with unique fingerprints, which will remain unchanged for the whole of their lives.
20.Very often biotechnology and genetics are the objects of negative criticism as interference in nature, a kind of lack of respect towards its rules.
