* For the first one this is what I would do... okay so we have the original equation for the first one & based off that this is what I would do... I would discover f ( 2 ) by inserting x equals 2. f…
Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…
Quetext About FAQ Contact Valerie Delucca Professor Di Lauro Biology 109- Anatomy and Physiology 6 December 2016 Into Thin Air Part 1: - Mt. Denali, Alaska, 17,660 Feet People tend to experience dizziness, headache, fatigue, shortness of breath,decrease in brain function, headache, dizziness, frostbite, hypothermia, etc. at higher altitudes due to a decrease of atmospheric pressure. Mark experienced a shortness of breath and could not seem to feel better even when he paused his climb to “take a breather.” This is very common for people who are not accustomed to the difference in pressure because of the difference of altitudes. Same goes for Emily who experienced a headache due to a decrease in oxygen in the air and therefore, in her body.…
Procedure 1- Set up the DAQ to output port 2 to send a binary data. 2- Run the LabView in continues mode, change the numerical input on the control panel, and observe the LEDs on the terminal block between (PB0- PB7).…
Lab #5: Introduction to Metasploit on Kali Linux Team: CRYPTERS 1 d. Why is it usually a bad idea to operate in the Linux environment as root? If you are unfamiliar with the concept of the root user, do a quick google search. It is always a good practice on any operating system to run your applications on a user level and leave the administrative tasks to the root user, and only on a per-need basis. Applications are meant to be run by users with non-administrative privileges.(Power December 4, 2010)…
A sketch or view of test setup and arrangement of gauges and loading protocol should be presented. It is not clear the location of gauge 1 and 2 listed in Figure 11. Why the results of two mentioned gauges are presented in comparison with analytical one? Are the both of them comparable? Why the results of two gauges are different?…
Materials. Numerous substances in the experiment were used. The most frequently used was the unknown due to the need to test its physical and chemical qualities. When a solution of the unknown was made, 1.000 g of the unknown and 1.0 mL of water was used to make it. To test for the possible ions, 1.0 mL of silver nitrate and 1.0 mL of nitric acid were used for the ion test.…
The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if it’s positive or negative. Performing aseptic techniques is the most crucial step that requires the utilizing of transferring, inoculating, and storing bacterial cultures and media. Aseptic technique is defined as procedures that prevent contamination…
-SiO2@ON/glass was coated with poly(methyl methacrylate) (950 PMMA C4, Micro Chem, 2 mL) by spin coating (500 rpm for 5 s, 1,000 rpm for 5 s, 2,000 rpm for 5 s, 1,000 rpm for 5 s, SP-7200GT spin coater, Intec systems). The plate was cut into 4 pieces of 1.5 × 2.5 cm2 area (Refer to Figure S3), and then added to 5% HF solution (100 mL). In the first 1 min, the glass plate was detached from S-SiO2@ON/glass and removed. The S-SiO2@ON was further etched for 2 h. Caution: HF solution is extremely dangerous to be inhaled and touch. Thus, it should be handled with extreme caution and specific gloves in a good hood.…
Chemical changes are everywhere from everyday things such as baking to scientific things such as changing one gas into another. Physical changes are changes that can be observed with senses and change a certain property or properties to a substance but it still remains chemically the same. This can include changes in the state of matter, size and shape. Chemical changes are when the substance is changed chemically with its properties changing with it. The substance with change from one substance to another.…
EXPERIMENT: The effect of an acidic fluid on the activity of an enzyme INTRODUCTION: There are several factors that may influence the activity of an enzyme to include temperature and the pH levels. In order to better understand how the pH level affects the actions of an enzyme, the experiment will introduce different foods with acids and bases through mixture of direct contact. OBJECTIVE:…
catalysed by the transmembrane protein, adenylate cyclase, initiated by the release of GTP-bound α subunit. This increases the cytosolic levels of cAMP which then activates protein kinase A. This successively phosphorylates glycogen phosphorylase b stored in the cell, as phosphorylase kinase is initiated. Phosphorylation of glycogen phosphorylase b converts to phosphorylase a. This enzyme releases glucose-1-phosphate from glycogen polymers.…
In a biochemical reaction, enzyme which are proteins based compounds are used as a catalyst to produce a high yields. Proteins are the macromolecular components of almost enzymes, except for ribozymes, a class of RNA modifying catalysts. Enzymes are classified on the basis of their composition; simple enzymes are those composed wholly of proteins, whereas, complex enzymes which also known as haloenzymes, composed of protein plus a relatively small organic molecule. In this terminology the protein component is known as the apoenzyme, while the non-protein component is known as the coenzyme or prosthetic group where prosthetic group describes a complex in which the small organic molecule is bound to the apoenzyme by covalent bonds; in contrast if the…
To determine the unknown’s morphology is the first step in narrowing down possible organisms. A MacConkey and Mannitol Salt Agar tests were conducted on the organism and revealed the following. No growth on the MacConkey plate resulting in a gram positive bacteria and the Mannitol Salt Agar result showed it could be Staphylococcus or Micrococcus. (1) A gram stain test was used in determining the shape, size and arrangement of the unknown bacteria (1). The unknown organism is heat fixed onto the slide, in order for the organism to be stained.…
Enzymes are important substances made by the cells of plants and animals. There are called catalysts, which are substances that control how quickly chemical reactions occur without interfering at the reaction products (Daja and Treska 2015). Structure of both the enzyme and substrate, the substance on which an enzyme acts; provides clues as to how an anticipated reaction can be favored by the alignment of catalytic residues (Johnson 2008). The reaction of an enzyme is represented as: In this equation, when there is enough substrate (S) to completely alter the enzyme (E) to the enzyme substrate intermediate (ES), the first step in the reaction, the formation of ES is reversible.…
