The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

The family members themselves perform one of the factors that shared in the breakdown of their family by making self-interest before the need of the family. When this happens‚ family members alienated from each other and communication breaks down. The structure of the family is vanishing because everyone follows his desire and tries to achieve his aim on the cost of family scattering. Al is the member whose chief interests seem to be girls and cars. He feels that he stays with his family against

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

How much salt must be added to a glass of water for an egg to float? Hypothesis: I believe it will take 5 tbsp. of salt to be added to water for an egg to float. My reason is that I think that 5 tbsp. of salt is very heavy and will make the water heavy enough to float the egg. I must make the water heavy enough to float the egg. If the water has enough salt it will float. Materials Used: Eggs – 2 medium sized chicken eggs (2.0oz each) Natural Sea Salt Iodized Salt (table salt)

This egg drop experiment forced me to think and develop a design that I felt confident with. I developed several models and tested them numerous times‚ but could not settle on one. Eventually‚ I was able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing

Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and
