Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid rain? I also should say the most important thing that scientists are doing in their labs. Where acid rain is most effects on which states and does it affect human when we swim in a really high acidic ocean. Acid rain is a mixture of water and gases that have a pH of 5 or lower and it is found in our atmosphere. Acid rain is made

HSC Biology 9.4 The Search for Better Health 9.4-6 You have been looking at the different types of diseases that affect the human body and the natural defence mechanisms that maintain health. In this last part of the module you will look at how increased understanding has led to the development of a wide range of strategies to prevent and control disease. In this part you will have the opportunity to: • discuss the role of quarantine in preventing the spread of disease and plants and animals

Arrangement of Vascular Tissues in Flowering Plants • Xylem and phloem often are grouped together -> vascular bundle • Cambium -> lies in between xylem and phloem -> divide and differentiate -> form new xylem and phloem tissues -> thickening of stem Movement of Substances Into and Within Flowering Plants Entry of Water and Nutrients into Plants • Absorption of water -> root hairs -> grow into close contact with liquid around them • Thin film of liquid surrounding soil

The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

producer and distributor of fruit and vegetable juices. Industry Strategic Analysis Threat of New Entrants: In the fruit juices industry there are high entrance barriers because there are big companies that have economies of scale because of the great amount of products they sale‚ and this companies have machinery to make a lot of juices of different fruits and vegetables‚ making it easy for big companies to have economies of scale. Many of these companies not only make fruit juice‚ but have products

DIFFERENT STORAGE TECHNIQUES FOR FRUITS AND VEGETABLE Food spoilage: Every change in food that causes it to lose its desired quality and eventually become inedible is called food spoilage or rotting. Factors affecting storage life The natural limits to the post-harvest life of all types of fresh produce are severely affected by other biological and environmental conditions: Temperature: An increase in temperature causes an increase in the rate of natural breakdown of all produce as food reserves
