10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

Anoura fistulata‚ otherwise known as the tube-lipped nectar bat‚ is a nectarivorous species endemic to South America (Mantilla-Meluk et al. 2009). A. fistulata specializes in feeding on the nectar and pollen from larger flowering plants‚ but also frequently hunts insects to round out it’s diet (Muchhala et al. 2005). However‚ unlike other species of the same genus A. fistulata has co-evolved as a pollinator of the bellflower Centropogon nigricans (Muchhala et al. 2009). C. nigricans has developed

Bob Garfield‚ You Tube vs. Boob Tube According to Garfield‚ most people create or share video content online because everyone wants to be a movie star and posting home made videos of them self gives them a chance at that. And to give other people a chance to view it. I do agree with it because I think it gives people a chance to feel accepted. Hollywood’s role in video entertainment has changed in that the internet video sites such as you tube are taking over the way people view television. Advertisers

advancement in the field of medicine has been used recently which helps childless couple to have their biological child. This advancement includes what the people call in vitro fertilization which results to what is commonly known as the test tube baby. In Vitro Fertilization (IVF) is the most common among the high-tech fertility treatments. It can help the woman conceive if she has ovulatory problems‚ if they have problems in the fallopian tubes‚ if their partner has low sperm count‚ or other fertility

1. Shell and Tube Heat Exchanger – Working Principle The shell and tube heat exchanger comprises of two major things as its name state "Shell and Tube". The shell is a major vassel with quantities of tube inside it (Jalmood‚ n.d). Shell and tube heat exchangers are helpful for pressurized application. Heat is exchanged between the liquid in the tubes and the liquid inside the shell. Configuration of the tube pack is such that‚ all the section sides of the tube could be joined with a typical header

Research project #2 Test Tube Meat Scientists have recently traveled to the Netherlands to check out different laboratories researching test tube meat. This is a recent study and may seem far-fetched but we could be eating this meat in the next couple of years. With a new study like this there will be many controversial Pros and Cons. The two articles I researched online were; Burgers From A Lab: The World Of In Vitro Meat and the other is from Beefmagazine.com: Test Tube Meat. Both of the articles
