for developmental research. (4 marks) Organisms | Advantages | Disadvantages | A. thaliana used for plant development research | 1.) Tiny Genome- Therefore it is easy to study the genes and also to manipulate the genes.2.) Short Life Cycle- Experiments conducted on the A.thaliana will have observable results fast as the development of the plant is rapid.3.) Small size-can be cultivated in a tiny space and this is vital because research areas usually have space limitations.4.) Male and female

genetic inheritance pattern is X-Linked traits (Brooker 1999). Drosophila‚ or fruit flies‚ was chosen for the study of X-Linked traits for multiple reasons. Fruit flies are small insects approximately 3mm long‚ and thus use minimal space when compared to other species. The diet of fruit flies is simple and does not require extraneous foods or materials (Ullrey 2011). Additionally‚ the life cycle of fruit flies is quite short‚ lasting approximately 26 days for a female and approximately 33

the standard test for sugar in the urine of diabetics. Some of the solution to be tested (this could be the juice or extract of the fruit or vegetable in question) is mixed with Benedict’s test reagent (by volume‚ usually about 4 solution to 1 reagent) and heated almost to boiling. A color change from the blue of the reagent to almost any other color -- green‚ yellow‚ orange‚ red‚ brown -- is an indication of the

Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance‚ where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the "father of genetics‚" Gregor Mendel. He determined that individuals have two alternate forms

The Forbidden Fruit It seems like the greatest anecdotes revolve around an apple; Adam and Eve damned all of mankind for an apple and an apple inspired Newton’s whole life work. The scrumptious Frisbee-shaped apple pie that Gary Soto’s six-year old self snatches is almost worth spending the rest of eternity in hell. The author compels the reader that the rush and risk of stealing appears pleasuring enough when you enjoy it‚ but guilt fills the conscience when it vanishes. The use of diction‚ imagery

The Feeding Behavior of the Protist known as Tetrahymena vorax Abstract The purpose of this experiment was to study the rate of phagocytosis of the specific protist known as Tetrahymena vorax. This certain kind of protist feeds at a normal rate when conditions are normal. We began the experiment of understanding how Tetrahymena feeds at normal temperatures. Doing so‚ we allowed the Tetrahymena to feed at specific time limits and then killed the protist with gluderaldheyde to detect how much

Abstract: The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results
