Tissue structure experiment .

Histology is the branch of biology which is related to the study of tissues.

The following are the general steps which are to be taken to examine a tissue under a microscope.

Fixation protects the tissue from autolysis. It hardens the tissue due to which it becomes easier in cutting the thin sections of a tissue. Fixation is done with the help of chemicals like aldehydes.

Selection is done to isolate the particular tissue which we want to observe.

Paraffin waxing is done so that the tissue remains embedded.

Staining is done so that the tissue can be seen and separated from other tissues.

The tissue can then be observed under a microscope.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
