1. Arnav found a scratch on the body of his car. which of these is most likly to have caused the scratch?

Explanation

The most likely cause of the scratch on the body of Arnav's car would be a metal key. This is because metal keys are hard and can easily scratch the surface of a car's body. Sponge, eraser, and the skin of a dog are not typically hard enough to cause a scratch on a car. Therefore, the metal key is the most plausible explanation for the scratch.

4. Plants loose excess water thruough parts like leaves, stems and flower

In order to reduce the loss of water , which of the following parts is missing in some desert plants?

Explanation

Desert plants often face extreme arid conditions, where water is scarce. To adapt to this environment, some desert plants have evolved to reduce water loss. One of the ways they achieve this is by reducing or completely eliminating their leaves. Leaves are the main site of transpiration, where excess water is lost through tiny openings called stomata. By lacking leaves, desert plants minimize the surface area available for transpiration, helping them conserve water and survive in their harsh surroundings. Therefore, the missing part in some desert plants that reduces water loss is leaves.
