How to Read and Use Histograms How to read the Histogram. A histogram is a graphical representation of the pixels exposed in your image. The left side of the graph represents the blacks or shadows, the right side represents the highlights or bright areas and the middle section is mid-tones (middle or 18% grey). I forget that there is a button “picture style” on my camera. – I use the camera histogram to see if the exposure is in the ballpark. – If the histogram indicates very high contrast (as explained in this article), I use the automatic bracket function.

What Are the Similarities and Differences of Histograms, Stem-and-Leaf Plots, Box Plots and Scatter Plots? A histogram is a type of bar graph that shows how many of something occurred, also called the frequency. A histogram looks like a bar graph except that the bars are adjacent, that is, there's no space between them. Without any space between the bars, you can see how the counts or values are related to each other.

Life Sciences Under the Microscope Histology and Cell Biology Histology, which is the microscopic study of tissues, would not be possible without the use of microscopes. A histologist will be able to learn valuable information with regards to the functional morphology of both human beings and animal. This helps with important discoveries concerning the cells and body systems. See Histology Slides. The importance of microscopes in life sciences can never be overestimated. Following the discovery of blood cells among other micro-organisms, many other discoveries were made through the use of advanced instruments.

histone / histones Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes.he beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer.

- Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. In contrast, cytopathology examines free cells or tissue fragments.he second method of histology processing is called frozen section processing. This is a highly technical scientific method performed by a trained histoscientist (a Medical Laboratory scientist specialist in Histopathology.

Histograms Histograms What is a histogram? A histogram is a plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. This allows the inspection of the data for its underlying distribution (e.g., normal distribution), outliers, skewness, etc. An example of a histogram, and the raw data it was constructed from, is shown below:

Transformation (genetics) In molecular biology, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material (exogenous DNA) from its surroundings and taken up through the cell membrane(s).ransformation is one of three processes by which exogenous genetic material may be introduced into a bacterial cell, the other two being conjugation (transfer of genetic material between two bacterial cells in direct contact) and transduction (injection of foreign DNA by a bacteriophage virus into the host bacterium).
