Answer:
1)Biodiversity of an area refers to the vast number of species of plants, animals and microorganisms existing in that area.
2)Fauna refers to animals, whereas flora refers to plants
3)Yes, I agree with the statement. Forests provide plant cover to check the flow of water. If forests are removed, then floods will occur.
4)False.
Endangered animals are those species whose numbers are diminishing at an alarming rate and face an immediate danger of extinction.
5)If all trees in a forest are cut, it will lead to erosion of soil.
6)Grazing by cattle should be controlled for forest conservation.
7)True.
Soil erosion is the removal of top layer of soil that is most fertile. If not checked, soil erosion ultimately leads to desertification.

Explanation:
Gene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA.
Some living thing's bodies are weaker than others. For the species to live, the strong ones of the species will not get sick, reproduce and create strong offspring. The weak will die out.
