Answer 1

Answer:

1. Amoeba multiply itself by the process of binary fission. Amobea doublesits nucleus and cytoplasm and divided the parent cell into two daughter cells.

In hydra, actively dividing cell divides continuously and forms a outgrowth projection called bud. The bud grows and seperates from parent cell after getting maturity.

2. A gland is an organ which produces and releases substances that perform a specific function in the body. There are two types of gland. Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream.

3. Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. In contrast, each egg cell, or ovum, is relatively large and non-motile.

4. (i) There are no fixed boundaries. Boundaries are fixed and defined. Not usually open to the public. National Parks are formed by the State or central Legislature.

(ii) 1)A wildlife sanctuary Provides protection and suitable living conditions to the wild animals in their natural habitat. 2)In a wildlife sanctuary killing and capturing of wild animals is strictly prohibited. 3)It does not allow any human activity which disturbs the wild animals or their habitat.

(iii) To carry out the complementary activities of biodiversity conservation and sustainable use of natural resources, biosphere reserves are traditionally organized into three interrelated zones, known as the core area, the buffer zone, and a transition zone or 'area of cooperation.
