Answer 1

$here \: is \: your \: answer$

1) EVOLUTION

Evolution is change in the heritablecharacteristics of biological populations over successive generations. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

5)CHIPKO MOVEMENT OF BISHNOI

The Chipko movement or Chipko Andolanwas a forest conservation movement where people embraced the trees to prevent them from being cut. It began in April 1973 in Uttarakhand (then in Uttar Pradesh) and went on to become a rallying point for many future environmental movements all over the world.It created a precedent for starting of nonviolentprotest in India,and its success meant that the world immediately took notice of this non-violent movement, which was to inspire in time many such eco-groups by helping to slow down the rapid deforestation, expose vested interests, increase ecological awareness, and demonstrate the viability of people power.

3) the branch of biology and medicine concerned with the study of embryos and their development.

4) Darwin's Theory of Evolution byNatural Selection. More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

5) the theory of the origin of species advanced by the French naturalist Jean Baptiste de Lamarck.

6) The protection, preservation, management, or restoration of natural environments and the ecological communities that inhabit them.Conservation is generally held to include the management of human use of natural resources for current public benefit and sustainable social and economic utilization.
