of cardiovascular disease. The leading cause of heart attacks is CAD (Coronary Artery Disease). Cad occurs when plaque builds up in the arteries‚ the tubes that supply blood to the heart. After a while the plaque starts to build up and restricts the blood flow causing the muscles to work harder‚ this may sometimes cause some pain and discomfort. A heart attack occurs when the plaque totally blocks an artery. Doctors have many different ways to determine if a person is at risk for CAD.

Investigating the Limits of Cell Growth Background: To find factors that limit cell growth In multicellular organisms‚ In order for an organism to grow cells must divide through mitosis. Cell division happens after the cell is big enough so the daughter cells will be replicated without any flaws. The regulation and amount of materials that can enter and leave the cell is based on how large the cells surface area is. The rate of movement is also determined by the volume of the cell. Many factors like

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

Investigating Ratios of Areas and Volumes In this portfolio‚ I will be investigating the ratios of the areas and volumes formed from a curve in the form y = xn between two arbitrary parameters x = a and x = b‚ such that a < b. This will be done by using integration to find the area under the curve or volume of revolution about an axis. The two areas that will be compared will be labeled ‘A’ and ‘B’ (see figure A). In order to prove or disprove my conjectures‚ several different values for n will

Investigating the Biomolecules found in Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein)

Bacteria have invaded Lola’s lower lobe of her right lung and we shall report the invasion and document all we see. Let’s proceed. We are being injected into the femoral vein close to the groin area. The femoral vein runs parallel with the femoral artery through the upper thigh and pelvic region of the body. (Yahoo Health‚ 2013) Being one of the larger veins in the body‚ the

Lab Design “Investigate the effect of a factor on the number of stomata of a leaf.” Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores‚ typically found under the leaf (lower epidermis)‚ that control the gas exchange of transpiration‚ where water vapor leaves the plants‚ and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts
