Answer:
1. Obtaining energy
2. responding to a stimulus
3. reproduction
4. excretion
Explanation:
1. All living organisms require energy for their life processes. This energy is derived from food. The food we eat contains biomolecules that store energy. The energy stored by these food molecules is released by a process called RESPIRATION. Image 1 shows a cat trying to obtain energy by feeding. The food will eventually be broken down to release energy.
2. Stimulus is any thing (whether internal or external) that causes a change in an organism. In image 2, a man is responding to a sudden change in his back, which is pain.
3. Reproduction is a characteristics of living organisms that involves the production of young ones. Image 3 depicts two cells undergoing fertilization (fusion of nuclei) to produce a new cell. In turn, the cell divides again to form two gametes. The cycle continues like that.
4. Excretion is the removal of waste products from a cell. According to Image 4, the cell allows a food particle in and releases the waste contents out of the cell.

The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.
<u>Explanation:</u>
Step 1:
All the sides of the cubes are equal.
Step 2:
Given,
a= 3 cm
Step 3:
Volume of the cube = a³
= 3 × 3 × 3
= 27 cm³
Hence, The volume of the cube is 27 cm³
