25 of the 50 animals I need need to be from different species, so there will be 2 animals of the same species. I will feed the first 25 animals, of different species, the berries from the tree for one week. Then I will feed the other 25 animals, of different species, berries that are known to not be toxic for sure. The 50 animals will be closely monitored for that entire week, especially their level of toxicity. The levels of toxicity of the animals that were fed the berries from the tree should closely match the animal of their same specie from the group of the 25 animals that were fed the berries known to not be

In order to test my hypothesis, eight separate plots containing a certain amount of Simploids and plants were used. A total of four plots were utilized as the experimental group, in order to conduct the analysis and test the effects of parasites on the health of the Simploids. The remaining four plots were used as the control group, where they resembled the experimental groups in terms of sample size but received no exposure to parasites. Thus, the four experimental plots that were infested with parasites were each given a sample size of fifty Samploids and fifty plants. This was done as a form of replication in an attempt to identify if there were any outside factors that could be contributing to a change in the Samploids’ health. Thus the control group was composed of the same variables as the experimental group with the exception of parasite exposure.

The outcome of this lab proved for the prediction to be true. The organisms in the aquatic chamber died out and the water quality slowly deteriorated before the lab ended. Although the organisms eventually died, there was a time when the aquatic chamber was able to support life. The aquatic chamber had its own food chain where the fish ate the plant to stay alive. Furthermore, the water quality of the chamber began to deteriorate over the few weeks becoming a cloudy murky brown color.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

1.) My hypothesis that the insects would be most repelled by the lemon plant extract was not supported. Our key findings in the experiment do not support my hypothesis because the lemon had a 60% repulsion response and was the second most repulsive behind orange with a 70% repulsion response. Although the Earthworms were repelled by the lemon plant extract, they were more so repelled by the orange plant extract. 2.)

To test a hypothesis about a given variable, experimental and control groups are tested in parallel. Which of

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

The Demographic environment relates to the structure of populations (Oxford Dictionaries | English, 2017). The factors that contribute to the demographic environment relevant to this report are location and density of the population.

Population size refers to the estimated total number of individuals of a specific species in a given habitat or area at a given time. Population density is the number of individuals of a specific

Besides the total size of the population, one of the most significant demographic characteristics of a population is the age and sex structure. The immigration has had a major influence on both the size and the age structure of the U.S. population. The U.S. population has experienced remarkable growth since 1950. The number of women slightly outnumbered the men.

The purpose of the control group is the keep the experiment consistent throughout for the best results. For instance, four white carnations are placed in four vases with plain tap water. Two of them have other liquids added to them, making the plain tap water flowers the control group. They stay consistent

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and

An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education,
