Scanning Objective Lens • Most objective lens are color-coded, including scanning objective lenses. Scanning objective lenses usually have a red band around them and provide a magnification of 4x. The purpose of this lens is to provide an initial magnification of the specimen being studied. Although the scanning lens does not provide a great deal of magnification, it is important to use this lens with every specimen to initially bring it into focus and center it within the field of view. Low Power Objective Lens • Low power objective lenses typically provide a 10x magnification and will have a yellow band around them.
2. Why is it important to stop the chromatograph before the solvent reaches the top of the paper ? Because if the solvent gets to the top, I could miss the measuring points because they would keep moving. 3.Why is
| Advantages(s) | * Can notice the specimens that are living and lifeless * Inexpensive | Higher resolution and magnification | Disadvantages(s) | Lower resolution and magnification | * Extremely costly * Specimens must be lifeless | 4. Which part of the compound light microscope should be adjusted if? a) The image appears blurry under low power? – coarse adjustment b) The image appears blurry under high power? – fine adjustment c) The image appears too dim?
To determine if hyphae grow at the same rate, graph the results of table 2 and compare the slopes of the 3 hyphae from the slide preparations. 11. To determine if mycalolide B affects fungal tip growth and nuclear position repeat all the steps except in step 2 need to add mycalolide B and let it incubate for 10 minutes. Make sure to label the slides with the
The Checklist is based on the rubric that will be used to grade the final draft. Copies of the Checklist and the rubric are attached. Read over the Checklist and the rubric before you submit your draft to your teacher. The first draft assignment is worth 120 points, so be sure your draft includes everything in the Checklist. For example, one of the Checklist items states, “The research paper has an introduction.” If your draft has an introduction, you will receive 10 points.

(Ahmed, et al., 2013) The gradient magnetic field comes about by the actual process of the MRI. The radiofrequency is switched on and off during an examination. Because of this the gradient magnetic field is born. These waves can produce a current in the pacemakers. They can cause the pacemaker to become faster or slower.
Suggest two reasons for this change. Task 2 Press back but not clear and change the number of chips to 10 but leave the acid concentration at 1.0 mol/dm3 . Click start and take readings approximately every 3 seconds (by clicking the take readings button) until the mass reaches 0.0 g. Stop the reaction immediately. Plot these results on the same grid as the results of your first experiment. How does the rate of reaction in Task 2 compare with the rate in Task 1?
First of all, contact lenses and eyeglasses are different in terms of users’ convenience. Using contact lenses is more complicated compared to using eyeglasses as the way of wearing is totally different. Wearing contact lenses might be hard for you since you have to apply them directly on your eyes, and you also have to follow the steps of wearing contact lenses. For example, you have to make sure that your hands are clean, and be sure that you rinse your contact lenses with the solution before wearing them. Also, you need to insert the lens by using the forefinger on your opposite hand, and holding up your upper eyelid to prevent you from blinking.
This may have entered the detector during the experiment, skewing the data. This is an experiment that needs to be performed in total darkness, but it was not possible due to the blinds not blocking out all of the sunlight and the computers being on throughout the experiment. A final cause of error may have been the yellow and green filters2. They have been inadequate, insufficiently blocking high frequency light. These unwelcome high energy photons would have ejected high energy electrons, allowing them to surpass the cathode-anode potential, which would have increased the measured stopping
