closer the heart rate should be to the resting heart rate of the Daphnia. Possible errors that could have gone wrong are the duration given to allow for the absorption of the different concentration of salt solutions due to the limited time during the lab period and the distinguishing of the separate heart beats and the inaccuracy of a constant time being off by points of a

Introduction The purpose of this lab was to calculate and determine the optimal dosage of ultraviolet (UV) light to expose Saccharomyces cerevisiae (S. cerevisiae) to that would result in a survival rate of 20-40%. Saccharomyces cerevisiae commonly referred to as baker’s yeast is a single-celled eukaryote. Yeast is capable of growing as either a haploid or a diploid cell. The diploid cell can reproduce mitotically or sporulate‚ a process initiating meiosis and forming an ascus with four spores (Sacchromyces

Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

When one wakes up in the morning with bad breath‚ do they rinse with mouthwash and say "it’s never been fresher?" The Onion is a website dedicated to writing about controversial topics with a twist of humor. One article in particular‚ "Girl Moved to Tears By ’Of Mice and Men’ Cliff Notes‚" preaches out about losing the meaning through all the shortcuts that younger generations seek. The youthful Grace Weaver was gripped by the retelling of the George Steinbeck classic‚ feeling this emotional connection

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

grow onions Today‚ most people simply eat onions raw or cooked‚ in about a thousand different ways. Onions are warm-season veggies and‚ however you plan to use them‚ you can grow them anywhere following the following easy steps: a) Buy started plants at the nursery.
