Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light

succinate to fumarate‚ thus loses hydrogen ions and electrons for use in generating ATP. It is important to know what inhibitors affect the activity of this enzyme which eventually will affect the whole process of cellular respiration. In this experiment‚ 1M Malonate( CH2(COO)22-) and 0.1M of Sodium Fluoride (NaF) ‚were employed as inhibitors to the enzyme succinate dehydrogenase to assess their effect on cellular respiration. Malonate is a molecule that inhibits the oxidization of succinate. Besides

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

Tomato Sweetness Jessica Pursell American InterContinental University 01/18/2015 Biology IP2 Introduction You and your neighbor have small kitchen gardens where you both grow tomatoes. His blotchy green and red tomatoes taste much sweeter than your perfectly uniform red ones. Could the sweetness of the tomatoes be effected by the green chloroplasts in the fruit? Hypothesis I personally think that the green chloroplasts do play a part in the sweetness of the tomatoes because it doesn’t
