What is photorespiration?

When during hot, arid days, stomata opens only a little, enough carbon dioxide is not taken, so rubisco takes up oxygen and uses it in the Calvin cycle instead of carbon dioxide, this process of light dependent uptake of carbon dioxide and release of oxygen is called photorespiration.

What is a link? Write the various ways of linking a document with another.

The link is a feature in HTML that allows the user to connect two webpages or documents. A link has two ends -- called anchors -- and a direction.
