Biology Unit 2 Module 2 1.1: Explain the uptake of ions by active transport in roots; * Emphasize the role of the endodermis. Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

Biology - Main Questions And Answers: Complete the table with a tick if the statement in the first column is true‚ for each process. Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

cells‚ the phages are able to produce more viruses‚ which are released when the bacterial cells rupture. DNA’s Role Revealed Hershey and Chase carried out the following experiment: Step 1 T2 phages were labeled with radioactive isotopes. Step 2 The phages infect E. coli bacterial cells. Step 3 Bacterial cells were spun to remove the virus’s protein coats. Hershey and Chase concluded that the DNA of viruses is injected into the bacterial cells‚ while most of the viral proteins remain outside

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

Lauren Spillers Biology 1408 February 5‚ 2013 Lung Cancer Lung cancer is the number one form of deadly cancer in the United States. It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

Educ 150 Classroom Job Shadow Reflection Taylor Babbis Shepherd University I use to think that being a teacher was going to be a short eight hours of teaching and being with children. Having summers off made being a teacher seem a lot more beneficial to. Being a teacher seemed to be the easiest career choice out there for me. After viewing the second grade classroom in Shepherdstown Elementary it is safe to say that I have changed my opinion of teaching. There is unquestionably another side to
