The smallest relative difference that is not statistically significant is stress management at -0.63. The reason that this ratio is not statistically significant is because the value used to determine significance was lower than 0.05. The smaller t ratio has an increased p value and the odds of being able to reject the null hypothesis are diminished. This result means
Bio, 2008). The availability of these resources will determine the carrying capacity, the number of individuals that an environment can sustain (Campbell et al 2009). The amount of resources available and the population size are likely to be influenced when other species are present. With limited resources being available and having more than two species sharing those same limited resources population growth and size are more than likely going to be low. Plants that are grown under crowded conditions tend to be smaller and less likely to survive (Campbell et al 2009).
Daniel Hawkins Nachiket Pendse Biology Lab Sec. 053 9 October 2012 Results For all three trials the generic recycled paper towels held the most amount of weight. The first trail it held 1,407.28g, the second 1,378.56g and on the third trail it held 1450.36g. Also for all three trails the regular generic paper towel held the least amount of weight. In the first trail it only held 315.92g, second 325.90g and the last trial 301.56g.
Which gene(s) were expressed less in Grandpa Joe’s lung cells? How do you know? * Genes three and six were expressed a lot less since they were not being expressed in the wet lab test and there ratios also were very low. The ratio of gene two was equal to one which means it’s not affected. Were there any genes not expressed in either cell type?
Which wood burns the fastest? In my research I found that because of the lower density of soft woods they burn more quickly than hard woods. When looking for a fast burning wood, I found most sources recommend using soft wood. I also found that the more resin (also referred to as sap) types of wood contain affects how it burns. The combination of high resin content and low density means easy ignition and a lesser burn time.
Lots of things are made from wood everyday but it has nowhere near the same production that hemp has. Along with what Dean Curran wrote, David A. Bainbridge writes in his article “Ecocomposite: Hemp Fibers” that, “Hemp can produce 3-8 dry tons of fiber per acre which is four times what an average forest can yield. Hemp grows very densely which does not allow room for weeds and no herbicides are needed for farming industrial hemp” (Bainbridge). Hemp produces more fibers then wood, it also produces more quickly and rapidly then wood does. Trees may take up to 20 to 30 years to fully grow before a person can use that wood and timber to create
The investigation took place at 3 specifically chosen sites where Oak trees, Quercus robur, acted as barriers to sunlight. This meant that nettles growing under branches weren’t exposed to sufficient sunlight in contrast to nettles growing outside the reach of branches. All other factors were controlled. Due to a restricted amount of time, it was assumed that the light intensities measured represented the average conditions at the site. Using systematic sampling to identify and measure the nettle leaves, a strong correlation between light intensity and nettle leaf length was found where nettles that were exposed to lower amounts of sunlight had greater lengths.
Armadillidum vulgare: Light vs. Dark Environments By:Mya Davidson Abstract It is hypothesized that an isopod would prefer a dark environment rather than a light environment based on its natural habitat of soil. For the light vs. dark experiment, a container had 5 isopods on the light side and 5 isopods on the dark side. A study was taken for 5 minutes where every thirty seconds the number of isopods in each dish was counted. The results showed that isopods, like its natural habitats, preferred dark places.
Value of the independent variable: The independent variable can be categorized by the height (and the species of the tree). The collected apples mass was measured by weighting the each sample with scales. In order to determine a difference in tree height, trigonometry was used. The angle to the top of the tree was measured using a clinometer and its remoteness from the tree was measured from the base of that tree. b.
The tropical rainforest is found between 10 ° N and 10 ° S latitude at elevations below 3,000 feet. Almost all rain forests lie near the equator. Only 2 to 3 percent of sunlight reaches the forest floor. The only vegetation that lives here has adapted to low-light levels. The forest floor is littered with leaves and decaying vegetation.
