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.
Use your keywords in the headings and make sure the first level (<H1>) includes your most important keywords. Never duplicate your title tag content in your header tag. While it is important to ensure every page has an <H1> tag, never include more than one per page. Instead, use multiple <H2> - <H6> tags.
