Besides using special non-proteinacous fluorescent dyes to label cellular compartments it is also possible to stain the area of interest with the help of proteins with preferences for distinct locations in the cell. These proteins can be linked to a fluorescent dye and visualized in the fluorescent microscope.
The HTML <body> tag is used for declaring the main content section of the HTML document. The <body> tag is placed after the document's head (i.e. between the </head> and the </html> tags). The basic tag is written like this <body></body>, with the document's content inserted between the opening and closing tags. On any normal-sized HTML document, you'll usually see the opening tag (<body>) near the top of the document and the closing tag (</body>) near the bottom.
The <img> tag defines an image in an HTML page. The <img> tag has two required attributes: src and alt. Note: Images are not technically inserted into an HTML page, images are linked to HTML pages. The <img> tag creates a holding space for the referenced image. Tip: To link an image to another document, simply nest the <img> tag inside <a> tags. The following attributes: align, border, hspace, and vspace are not supported in HTML5. In HTML the <img> tag has no end tag.
