Because the bug was dead‚ it was nearly impossible to compare it to any of the characteristics on the this. However‚ the anatomy could be compared. While the type of bug is unknown‚ the bug was black‚ along with some other few bugs of the same petri dish‚ which is most likely believed to be the same type.

Biological Macromolecules Lab Cells‚ the fundamental units of life‚ are composed of various combinations of organic macromolecules: carbohydrates‚ lipids‚ proteins‚ and nucleic acids. This lab exercise is designed to show you the qualitative tests commonly used to detect their presence. Objectives Test for the presence of monosaccharides by using the Benedict’s test Test for the presence of starch‚ a polysaccharide‚ by using the Lugol’s iodine test Test for the presence of lipids by using the

Biology assignment - In Vitro Fertilization. In Vitro Fertilization (IVF)‚ is the procedure whereby human babies are conceived‚ not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure‚ their infertility would render them childless. There are many aspects of

Vicera January‚ 2012 Ms. Santiago Abstract Humans especially for those who live in dirty community are prone to get disease such as cholera‚ diarrhea‚ fever and many more because there is an unseen specimen called bacteria. Bacteria such as e-coli and staphylococcus are the most common bacteria that can cause illness to mankind. According to the World Health Organization (WHO) 3 out of 10 people are infected by bacteria

INVESTIGATION OF THE INHERITANCE OF THE ROSETTE GENE IN BRASSICA RAPA By: Justine Poorbaugh Foundations of Biology 2 Laboratory Thursday 2:30 PM Professor Cheek April 21‚ 2011 ABSTRACT The Brassica rapa is a rapid growing plant that has a standard form and a mutant rosette form. Relative to normal plants‚ the rosette form is shorter and takes longer to flower. The mode of inheritance of the rosette gene was tested by crossing two true-breeding plants‚ one of each form. The F1 generation

non-infections. Infectious diseases are diseases that can be spread or transmitted from one organism to another. Non – infectious diseases cannot‚ be spread from one person to another. Infectious Diseases Infectious diseases are generally caused by microbes known as pathogens. Pathogens invade the host and can cause changes in the body that stop parts‚ or all‚ of the body working correctly. Pathogens contain antigens that are made of proteins or polysaccharides. The bodies immune system reacts to these

that is already allowing scientists to test new drugs and figure out the cause of birth defects. The process is very delicate because scientists must work with a four to ten day old blastocyst to get the stem cells. They put the stem cells into a petri dish along with proteins and enzymes. The stew of cells‚ enzymes‚ and proteins is what helps regenerate the bad tissues that cause diseases. “Blastocysts can also potentially be created from a donor egg”(“Embryonic Stem Cell Research:The Facts‚ Page

Planarian Behavior – Biology II Honor Overview Work in pairs for this lab. You will directly observe planarian movement. You will then formulate a hypothesis about planarian behavior‚ and propose an experiment to test this hypothesis. Your experiment should be focused on one of the various types of stimuli listed below. Your experiment must collect both qualitative and quantitative data. Think about how you can increase the sample size of your observations to minimize the effect of confounding

Continue adding drops of sodium hydroxide until the mixture is neutral (pH 7). 8 Pour the mixture into a petri dish and use a glass rod to ensure it is evenly spread over the surface. Allow to dry overnight on a sunny windowsill or radiator‚ or you can dry the plastic in a drying cabinet. Read more:

tested varying wavelengths of light to see which would cause photosynthesis to occur to the greatest degree in spinach leaf disks. The spinach leaves were hole-punched to form 60 disks. These disks were placed in a solution of sodium bicarbonate and dish detergent to create a vacuum and remove all of the oxygen from their environment. This vacuum caused the disks to sink‚ and floating of the disks would indicate that photosynthesis has occurred because they had produced oxygen. Light was filtered
