Worksheet 1 1. How would you explain the cell cycle to your patient? (20 points) Scenario: A 21-yearl-old lady came into the primary care network clinic to avail of health teachings and resources for first time mothers. After graduation from nursing school, Alisha Marston got married to her former classmate and now expecting a baby due in 7 months. After being given instructions for the blood work and necessary health teachings, I offered to further discuss how the fertilized egg in her body…

even after the dramatic change? The concept of a critical point is something that can be seen in many sciences. For example, in physics, there are critical points when water changes its state – once it falls below 0 Celsius, the water becomes an ice, and once it rises above 100 Celsius, it becomes a gas. An example of the critical point from history could be an invention of the phone. We can reach any person within a couple of seconds nowadays, whereas it was unthinkable before 1876. We can…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…

manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species to use when results are needed in a short amount of time (Jennings 2011). These two characteristics allow a variety of experiments to be conducted on D. melanogaster. For example, different strains of…

they need because of the lack of lipase. Along with lipase the pancreas also produces insulin and glucagon, two hormones inside body needs to break sugar down into the bloodstream. The optimum temperature for an enzyme to work at is 37.5 degrees Celsius, anything over 40 degrees will denature the enzyme and reaction time will rapidly fall. Shown in figure two is a graph of enzyme temperature. It is clearly visible in this graph that anything below 35 degrees or over 40 show a slow reaction rate…

Prep: In order for the experiment to be conducted, there needed to be an extract available in order to soak the 7 mm disc. The way that the spices were extracted was by taking both the fresh and dry spices (Zingiber officinale (Ginger), Thymus vulgaris (Thyme), Allium sativum (Garlic), and A. cepa (Onion)) and measured out 1.5 grams of each of the spices. For the fresh spices, they had to be chopped up finely in order to get an exact measurement of 1.5 grams like the dry spices and this also…

tube was plated on a nutrient agar using the streak method . The unknown test tube was then placed in a refrigerator to slow down any continued growth. The nutrient agar was labeled “VB TR1” and was placed in an incubator for 48 hours at 37 degrees Celsius. Following this procedure, I started to do research on microorganisms that presented the same type of symptoms (diarrhea and nauseous). After 48 hours, the plate was observed. There were multiple tiny whittish isolated colonies present, all of…

Are you a cheesecake lover? If the answer is yes, let me introduce you to some history of cheesecake briefly. Back into prehistory (previous time of invention writing in human history), cheeses had been around for a thousand years according to an anthropologist who excavated cheese molds (Bellis, 2014). However, the first cheesecake might have been made in Greece in order to eat good source of nutrition and energy. In 776 B.C. of the first Olympic Games, the evidence shows that it was served to…

Plan B 4.0 states that, “(t)he Earth’s temperature is rising. It has gone up 0.6 degrees Celsius (1 degree Fahrenheit) since 1970, and it is projected to rise by up to 6 degrees Celsius (11 degrees Fahrenheit) by the end of this century” (Brown, L. 2009); climate change is a highly controversial topic which many individuals argue for and against its occurrence on the planet. The issue of climate change has become gradually more pressing and there has been numerous research done by highly…

In 1969, Thomas Brock and Hudson Freeze of Indiana University discovered a new bacteria species in the Yellow Stone Park, that scientist thought it could not survive above 55 degrees Celsius. Thermus aquaticus is a typical gram-negative bacterium, meaning that its cell walls contain much less peptidoglycan and unlike gram-positive bacteria, gram-negative bacteria contain lipoproteins. T. aquaticus appears as either a rod or short filaments. When exposed to sunlight, it can exhibit a yellow, pink…
