They reproduce quickly and you would have a large amount of animals to take care of if you kept all of the newborns. Linear growth is a type of growth pattern where a population increases by the same amount at regular intervals, such as each month, year or decade. A population increasing by two individuals every month is an example of a linear growth. 2,4,6,8,10,12,14.. is the pattern that population data collects monthly and follows. A straight line is produced from the data when plotted on a graph.
9. Record observations for each hyphal tip in table such as the one below but do one for each hyphal tip and for two different slides. Calculate the speed of growth using s=distance/time. Table 2: Hyphal Tip with Growth Medium (Slide 1) Time(minutes) | Distance (um) | Speed (um/min) | | 1 | 2 | 3 | 1 | 2 | 3 | 5 min | | | | | | | 10 min | | | | | | | 15 min | | | | | | | 20 min | | | | | | | 10. To determine if hyphae grow at the same rate, graph the results of table 2 and compare the slopes of the 3 hyphae from the slide preparations.
September17.2013 P.4 Environmental Sources Of Bacteria Purpose: We did this lab to find out exactly which conditions would help to grow a bacterium the best. Materials: • Agar • Petri dish • Cotton • Incubator • Tape • Bacteria Procedure: 1. Mark bottom of Petri dish 2. Split petri dish into 4 sections and label the sections 3. Pour hot agar into dish 4.
How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able to make more chainobeads as time progressed. 4.
The relationship isnt linear because the amount of product didnt increase by the same amount between the amount of concentrations of substrate. As the substrate concentration increases the initial reaction rate continues to increase until a certain point where it remains the same no matter how many more substrates are added. The highest rate of reaction was 4g of substrate resulting with 8g of substrate producing the same result. What is the maximum initial reaction rate for this enzyme at pH 7? The maximum initial reaction rate for this enzyme at pH7 is 350 molecules of products formed per minute at 4g and 8g of substrate
I know it seems as if each year I go my co-pay goes up at least $10. Medical techs are growing rapidly and now, more than 36% of hospitals are prefering to use robotic surgery. That is certainly a step up in technology but very costly. Lab test are also driving up the cost. Newer machines, better testing, and a combination of training the techs to run and perform these test are all a contributing
He would see a decrease in urinary output as his kidneys worked to maintain volume in the body. 3. Marks blood pressure was low because his blood vessels had dilated to dissipate heat. His heart rate would vary depending upon what stage he was in. Initially it would rise in an attempt to compensate and hold the blood pressure up, but after awhile the body would tire and his heart rate would fall.
Title of Paper: Check Point: Population Size Student Name: Daniel Gurley Course/Number: SCI/275 ENVIRONMENTAL SCIENCE Due Date (MM/DD/YYYY): 06/08/2012 Instructor Name: Steve Renner The four factors that directly affect population size are birth rate, death rate, immigration, and emigration. The higher the birth rates of a species, the more likely the growth of the population, all else being equal. When talking about death rate, the fewer deaths within a population, the longer and more stable the population is likely to be. Immigration is the influx of members from surrounding areas. This is viewed as a growth in one area, but is really only a tradeoff for the entire species.
He discusses that although the population is growing, our planet may not have all the resources it needs to accommodate the growing population. Kunzig states that with the increasing population will the planet have the resources it needs to support our growing population? It is discussed that the death to birth rate is completely unbalanced with 5 births to 2 deaths every second, which is causing our population to grow drastically. It is also discussed how the life span has also gone up around the world and by the year 2045 there will be 9 billion people living on this planet. Both are very big issues to worry
A third sign is granulovacuolar degeneration, this is when the fluid-filled vacuoles are crowing inside the nerve cell. This condition is can only be observed in a careful sliced and analyzed brain tissue. However the cell having lost all its dendrites and nucleus the disintegrates vanish into the body waste system. With the depletion of nerve material the brain is actually shrinking and sometimes as much as ten perfect. The cells that Alzheimer Disease suffers from the more mental function the person loses, and soon the person will have little to no motor skills.
