telescope that different coloured filters heated up his telescope by different amounts. Using a prism he broke up visible light he put a thermometer in the different colours. He found that the temperature got more massive as he moved the thermometer from violet to red after this He then measured the temperature where there was no visible light ( red end of the spectrum) and it was the hottest. This is how he discovered infrared light. Herschel’s early observational work soon focused on the search for pairs

are used in psychology today to study questions about human behavior and allow scientists to study why these behaviors occur (Spear‚ 2007). Another school of thought of psychology is biopsychology‚ or behavioral neuroscience‚ and it is used to study the brain and the nervous system (Spear‚ 2007). The study of the brain is used to link biopsychology to human behavior (Spear‚ 2007). The Major Schools of Thought “Since the birth of scientific psychology over 100 years ago‚ four major schools have

The cause of the Earth’s Ozone layer depletion is man made gases called CFC’s and Halogens. These gases are emitted into the air from motor vehicles‚ factories‚ aerosol can’s and many other forms such as natural gases. The harmful gases rise to the stratosphere where the Ultra Violet Radiation then breaks them up and releases

ALDEHYDES AND KETONES Abstract Aldehydes and Ketones have certain characteristics in common. However‚ both couldn’t exist in the same compound. Some test for the presence of aldehyde was made for this experiment. These tests includes Tollen’s test‚ Benedict’s Test‚ 2-4-dinitrophenylhydrazine and Schiff’s test. All the tests conduted yielded same results‚ that is‚ formalin and benzaldehyde are aldehyde-containing compounds while acetone is a ketone. On the other hand‚ effect of acid concentration

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

either be aerobic or anaerobic. Gram positive bacteria have a simpler cell wall‚ with a large amount of peptidoglycan. Peptidoglycan is a polymer composed of modified sugars cross-linked by short polypeptides. In effect‚ the cell wall traps the crystal violet in the cytoplasm‚ concealing the red dye safranin in gram staining experiment. Certain gram positive species have virulent strains that are resistant to one or more drugs. Gram negative bacteria on the other hand are composed of lipopolysaccharides

positive‚ is violet or purple. Sakaguchi test is another color reaction test used in testing certain amino acids or proteins. This test specifically aims to detect the presence of arginine. The positive result for this test yields a reddish wine color or reddish-orange color. Ninhydrin test is a test that is used to detect or determine the presence of free alpha amino group. Ninhydrin targets the free amino acid group and free carboxylic acid group that produces a color reaction of blue-violet solution
