Ans. Littoral zone.
Littoral zone can be defined as the area of a rive, sea, or lake, which lies close to the shore. It is characterized by abundant sunlight, dissolved oxygen, nutrients, and high water motion. These characteristics make it suitable for marine life. Hence, littoral zone is enriched with various plants and animal species, and coral reefs.

Answer: 0.45
Explanation:
First note that the body that causes the body to move is its moving force (Fm) which is 9.0N
Since the mass of the body is 2.0kg, the weight will be;
W= mg = 2×10
W= 20N
For static body, the frictional force (Ff) acting on the body is equal to the moving force (Fm) since both forces acts along the horizontal on the body.
Ff = Fm = 9.0N
The normal reaction (R) on the body will also be equal to its weight(W) since weight acts downwards and the reaction acts in the opposite direction (upwards).
R = W = 20N
Ff = nR taking 'n' as coefficient of static friction between the drawer and the cabinet.
9.0 = 20n
n = 9/20
n = 0.45
The period of physical changes to sex characteristics that marks the beginning of adolescence in males and females is Puberty.
