What are the rules for biological drawings?

Rules for Biological Drawings

  • Rules for Biological Drawings.
  • Drawings, labels, label lines, title, and underlining must be done using pencil only on unlined paper (NEVER lined, graph, or coloured paper).
  • Drawings should be large, preferably 1 drawing to a page (2 maximum, unless otherwise instructed by your teacher).

How do you make a good biological drawing?

A biological drawing, in contrast, should only be made while actually looking at a specimen. It should be done only with sharp, simple pencil lines on white paper, without any shading or sketching. It should be done slowly and carefully, looking at the specimen every few seconds to ensure that the drawing is accurate.

What does a scale bar look like?

Scale bars, also called bar scales, look like a small ruler on or near the map. Since most map readers have some experience using a ruler, these are often easy for the reader to understand and use. ... Once inserted, you can also double click the scale bar to change even more properties.

How do you put a scale bar on a picture?

In the 'Analyze/Tools' menu select 'Scale Bar'. The scale bar dialog will open and a scale bar will appear on your image. You can adjust the size, color, and placement of your scale bar. Once you are finished click on 'OK', save your image, and you are done.

What is a scale bar?

A scale bar is a line or bar divided into parts. It is labeled with its ground length, usually in multiples of map units, such as tens of kilometers or hundreds of miles.

How do you calculate a bar scale?

Scale bar

  1. Measure the scale bar image (beside drawing) in mm.
  2. Convert to µm (multiply by 1000).
  3. Magnification = scale bar image divided by actual scale bar length (written on the scale bar).

How is Imagej measured?

Measuring and Counting Objects Go to Analyze → Set Scale. In the Set Scale window the length of the line, in pixels, will be displayed. Type the known distance and units of measure in the appropriate boxes and click OK. Measurements will now be shown using these settings.

How does ImageJ calculate area?

To measure the area of water that you highlighted in each of the three images, select the Rectangular Selections tool in the ImageJ toolbar and drag a rectangle over just the top image of the triptych. Choose Analyze > Set Measurements... and click the Area and Limit to Threshold checkboxes.

How do you calculate Feret diameter?

From Cauchy's theorem it follows that for a 2D convex body, the Feret diameter averaged over all directions (〈F〉) is equal to the ratio of the object perimeter (P) and pi, i.e.,〈F〉= P/π.

How is image intensity measured?

If you want to know the intensity of the entire image or a defined area within the image, there are several ways to do this: 1) You can simply hover the cursor over a given area in the image and read out the pixel intensity at that pixel on the toolbar. For RGB images, there will be three numbers, red, green and blue.

How do you measure intensity of a color?

The color value (color intensity) was measured from the UV absorbance. The color value of a food coloring solution is typically determined by measuring the absorbance in the visible range at the maximum absorbance wavelength. It is indicated as a value converted to the absorbance in a 10 w/v% solution (E10%1Cm).

How do you calculate intensity?

Prevalence = number of individuals of a host species infected with a particular parasite species -j- number of hosts examined. 2. Mean intensity = total number of individuals of a particular para- site species in a sample of a host species -^ number of infected individuals of the host species in the sample.

How is GFP intensity measured?

Flow cytometry and fluorescent microscopy are two conventional tools to detect the GFP signal; flow cytometry is an effective and sensitive technique to quantitatively analyze fluorescent intensity, while fluorescent microscopy can visualize the subcellular location and expression of GFP.

How do you analyze fluorescence images?

Determining Fluorescence Intensity and Signal

  1. To threshold your image, go to Image > Adjust > Color threshold. Slide the Hue slider to match the color- so that the fluorescent areas are selected.
  2. Go to Analyze > Analyze Particles > Display results. This will give you the area of fluorescent regions of your image.
  3. Add areas for all fluorescent regions.

How do you measure fluorescence intensity image J?

Measuring cell fluorescence using ImageJ

  1. From the Analyze menu select “set measurements”. Make sure you have area integrated intensity and mean grey value selected (the rest can be ignored).
  2. Now select “Measure” from the analyze menu. ...
  3. Now go and select a region next to your cell that has no fluroence, this will be your background.

What is corrected total cell fluorescence?

To measure the presence of a protein, we excite the fluorochrom (the dye) with a laser and take a picture. ... When this is done, it is called the Corrected Total Cellular Fluorescence (CTCF), which is a more usefull and significant measurement than just raw fluorescence data.
