A ’tropism’ is a growth in response to a stimulus. Plants grow towards sources of water and light‚ which they need to survive and grow. Auxin is a plant hormone produced in the stem tips and roots‚ which controls the direction of growth. Plant hormones are used in weedkillers‚ rooting powder and to control fruit ripening. Tropisms The direction of plant growth Plants need light and water for photosynthesis. They have developed responses called tropisms to help make sure they grow towards sources

Should Genetic Engineering Be Controlled by Law Victor Gatdula Waukesha County Technical College Allen Jackson Written Communications December 18‚ 2011 Abstract This paper explores scientists ’ points of view about genetic engineering. Some of them are sure that it should not be controlled by law; others consider that genetic engineering has crossed the line and as a result should be limited. Nobody doubts that with the help of genetic engineering we can treat some diseases‚ change

------------------------------------------------- Genetically modified crops Genetically modified crops (GM crops‚ or biotech crops) are plants‚ the DNA of which has been modified using genetic engineeringtechniques‚ to resist pests and agents causing harm to plants and to improve the growth of these plants to assist in farmers efficiency. Genetic engineering techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create

Assignment 2 Option 1 1. Introduction Language represents human’s experiences and different fields hold different ways of language using. The language of science actively constructs scientific reality‚ i.e. a way of looking at the world‚ the roles assigned to readers and the way of organizing information (LING337-nominalisation). However‚ science may be presented diversely according to the different intended audience‚ purposes and modes. Three texts chosen in this paper are all concerned with the

SARS-The Commonly Uncommon Cold Acute respiratory illnesses are among the most common infectious diseases known to humans as they account for nearly half of all diseases that plague our species. Of these respiratory illnesses‚ viruses are the cause in 50-75% of reported cases. The Corona Virus known as SARS or Severe Acute Respiratory Syndrome is one of the most recently highly publicized respiratory illness that has drawn a surge of research since the first reported cases of the virus in Southern

The Grape Industry Most grapes come from cultivars of Vitis vinifera‚ the common grapevine; and its cultivation began approximately 6000 to 8000 years ago (B) (This et al.‚ 2006). Grapes can be eaten raw and used for making wine‚ raisins‚ juices‚ jellies‚ vinegars‚ and seed oils (B). The grapevine has played an essential role in history‚ religion‚ and industry worldwide. Archaeological evidence suggests that the first wine production has originated between the Black Sea region and Iran‚ and by the

including those previously implicated in cancer. INTRODUCTION Numerous methods exist to characterize transcriptomes and to measure gene expression at both the transcript and exon level (1–5)‚ and recent work (6–8) indicates that much more of the genome is transcribed than previously thought. Techniques to map transcriptional start sites (9–11)‚ quantitatively measure splicing events (12‚13)‚ and discover mutations in the transcriptome (14) have been described. Analysis of full-length cDNA data generated
