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

The oxidation number of an atom of any free element is ZERO. Means to say there is only one kind of atom present, no charge.

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 purpose of this experiment was we were trying to see if the number of arthropods would be significantly different in sparse and dense areas of the woods. Ms.Ehnert provided us with the design of a trap to set up in the woods so we could more actually count the amount and types of bugs that we find. The trap was a cup filled with anti-freeze that we put in the ground and then covered it with a paper plait, but raised it so bugs could get in and bigger animals couldn’t. We waited for a week to collect the results and then counted all of them and sorted them. My hypothesis was based off of common sense, the simple assumption that less trees equals less arthropods and more trees equals more arthropods. I knew that living things need a habitat

The mean voltage of the battery terminals while connected to the identification resistors is presented in Figure ‎4 12. These samples have been pulled out from the voltage sensor of the PEB panel. The voltage decreased as expected from 12.53 to 12.5 during first 20 seconds of connection to the

The hypothesis for this situation is that the plant that is not doing very well is that it is not getting the same amount of sun as the plant that was doing really well. Another possibility is that it’s not getting enough water as the other plant so it could not be doing as well because of those two

Introduction: In this lab we are trying to examine on evolution. To see the change over time. Evolution shows where an organism comes from, so if we retrace it to the beginning of its time we will be able to know more about the organism and its ancestors more reliable than an opinion. Measuring the skulls and comparing the the measurements can help us see how far the animal has came and how it changed over time. Also get to see who's related to who and how.

As discussed in lecture, the determining factors of a substitution reaction is likely to occur in either S_N 1 or S_N 2 by: substrates, leaving group, strength of the nucleophile, and the type of solvent.

The nova labs show how all species are related through numerous traits. For example, a dog, fish, insect, and kingsnake all have bilateral symmetry in common. This shows how species have evolved from each other. The comparative anatomy lab compares different traits between species like chimpanzees and humans. Humans have very similar alleles with chimpanzees. Their physical features are very much related as well. The stickleback fish lab proves evolution through a species. The stickleback showed different traits depending on where they live. The differences were shown between freshwater and ocean sticklebacks. The different traits are evidence that the stickleback has adapted to a new environment. In conclusion, there are many ways to prove evolution through history. This also gives insight on future

Sub Aim 2.1. Generate global transcriptional sequencing data for CML and MLL cells to investigate the response of malignant cells to SMYD2 inhibitors.

The overall objective of the experiment was to compare the stress response two yeast strains, S. pombe and S. bayanus. We also looked at what genes were involved in ESR. The environmental stress tested was sorbitol treatment. In S. cerevisiae, the addition of sorbitol to the yeast growth media resulted in hyperosmotic shock similar to if the yeast were exposed to potassium of sodium chloride (Gasch, 2014). We compared the gene expression changes between the three species.
