Compounds called proteins and phospholipids make up most of the cell membrane. The phospholipids make the basic bag. The proteins are found around the holes and help move molecules in and out of the cell. Cell Membrane A cell membrane of the cell. It gives the cell its shape, it is the outer covering of the cell made up from phospho-lipid-protein bi-layer, which allows the materials to enter and to exit.
Renard Coats Intro to Networking NT1210T Lab 2.2. Network Drives Exercise 2.2.1 If an organization has 30 users, each with his or her own PC, what is the comparative cost of buying a $ 120 printer for each user versus the cost of buying a single , higher-capacity $500 printer that can cost of having two additional backup printers for the office compared to having individual printers? How many shared printers can be purchases and still be less expensive than individual printers? 30 users X $120 for the price of each printer = $3600 30users use a $500 printer Difference is $3100 savings using one printer The drawbacks to having only a single printer are too much information loading at the printer causing it to crash. Two back up printers $1000 VS 30 users X $120 for the price of each printer = $3600 30 users X $120 for the price of each printer = $3600 DIVIDED BY $500 printer = 7 printers can bought and still be less expensive than each user getting individual printers Exercise 2.2.2 If each of the 30 users in an organization prints an average of 22 pages per hour and a shared printer has the capacity to print 180 pages per hour, how many shared printers will be needed to prevent overloading each printer’s capacity?
At a stimulation frequency of 15 Hz how many stimuli were there per second? There were 15 stimuli per second. Results Table 4: Measurement of Threshold Stimulus Force (gf)(Motor neuron 1) 100 mV 0 200 mV 0 Voltage (mV) 300 mV 0 400 mV 0.105 500 mV 0.105 Effect of Stimulation Value on Twitch Contraction Force 1. What is the threshold stimulus? The threshold stimulus is 400 mV.
The tax on the year 1 deprecation would then be $28,050 * .40, which equals $11,220. After adding $11,020 to the $15,000 in savings, the cash flow for year 1 would equal $26,220. For year 2, the depreciation expense would equal $85,000 * .45, or $38,250. The tax on the year 2 deprecation would then be $38,250 * .40, which equals $15,300. After adding $15,300 to the $15,000 in savings, the cash flow for year 2 would equal $30,300.
| | | |The protein ___myosin____consists of two twisted strands with globular cross-bridges projected outward along the strands. | |__actin___ is a globular protein with myosin binding sites. What two proteins are associated with it? Troponin and tropomyosin | |According to the sliding filament theory of muscle contraction, if allowed to, the myosin crossbridge attaches to the binding site on the actin filament | |and bends, pulling on the actin filament; it then releases and attaches to the next binding site on the actin, pulling again. What is preventing this from| |happening continuously?
Rough ER transports these proteins to the regions in the cell where it is needed. | Ribosomes | A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. | the main thing they do is that they arrange the strands of the amino acids for use of the other parts of the cell and ultimately the body. | Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER.
Coal hypothesis = If activated carbon is added with 100mL of water, it will increase the pH over 48 hours. 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. a. Pyrite hypothesis accept/reject = I would accept the hypothesis, seeing as how the pH reduced from 6 to 2. b.

Understand the interactions of actin and myosin in muscle contraction and in “localized” muscle contraction (e.g. pseudopodia and cytoplasmic streaming) Understand the structure and function of cell walls in plants. What other kinds of cells have them? What kinds of molecules make up the extracellular matrix in animals? Where do they come from?
When a sport drink is needed h. An individual will burn 200-500 calories during a standard workout that is 30 minutes long. However, Gatorade has about 150 calories in it so a more strenuous workout is needed for Gatorade to be beneficial i. For training over an hour at medium to high intensity, look for a drink that provides between 13-19 grams of carbohydrate per 8 oz serving, and at least 80-110 mg sodium 4. Water is insufficient j. Thirst mechanism in the brain is stimulated by the osmotic effects of electrolytes in body fluids and effective sports drinks will also contain the correct electrolyte to maintain the osmotic drive for
