1.Answer: D

The order of these pairs of bases along the DNA molecule codes for all the different proteins. A section of DNA that codes for one particular protein is called a gene. Each chromosome contains thousands of different genes. The genetic code of the DNA always remains safe inside the nucleus.

Saliva contains the digestive enzyme, amylase, which works on carbohydrate starches, like breads, potatoes, or pasta, to help break them down into simple sugars. Some digestion of fat also starts in the mouth when a small amount of lingual lipase is secreted and mixes with saliva.

8.Answer: B

Cells generate energy from the controlled breakdown of food molecules.

9.Answer: A

The acceleration of the moving body at any instant of time is called instantaneous acceleration.

10.Answer: A

Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.
