Answer:

hope my answers can be helpful to you

Explanation:

1)Sieving is  a method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. Thus, it cannot separate two substances in a mixture which have the same size. For example, it cannot separate a mixture of chalk powder from flour.

2)A reversible change is a change that can be undone or reversed. If you can get back the substances you started the reaction with, that's a reversible reaction. ... Examples of reversible reactions include dissolving, evaporation, melting and freezing.

3)A flower consists of sepals, petals, stamens, and pistils. A stamen has two parts called the anther and the filament. A pistil has three parts called the stigma, style, and ovary

4)  Flower with joined sepals is Periwinkle (Sadabahar) Datura, Cotton and Hibiscus (China rose).

   Flower with separated sepals is Rose, Lotus and Magnolia.

5)There is only one movable joint in the skull. That is the joint connecting the lower jaw, or mandible, to the rest of the skull. All the other bones in the skull are firmly attached to one another by sutures.

6)A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce. ... The main components of a habitat are shelter, water, food, and space.
