The statements which are true for mechanical waves are mechanical waves transfer matter, mechanical waves requires a medium, and an example of a mechanical waves is a sound wave. Thus, option A, D and E are correct.
What is electromagnetic wave?An electromagnetic wave can travel in a vacuum, and a mechanical wave cannot. Electromagnetic waves are waves which can travel through the vacuum. Electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light.The energy transport through a medium involves the absorption and re emission of the wave energy by the atoms of the material.
Mechanical waves require a medium to travel so that they can transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves.
Therefore, The statements which are true for mechanical waves are mechanical waves transfer matter, mechanical waves requires a medium, and an example of a mechanical waves is a sound wave. Thus, option A, D and E are correct.

Forest A consists of only Oak trees and Forest B has Oak trees, Maple trees, and some pine trees. Which of the following is true?
Question 3 options:
Forest B has more biodiversity than Forest A.
Forest A has more biodiversity than Forest B.
Forest B, which has more tree species, is more biodiversity compared to Forest A that has just one tree species. The true statement is: "Forest B has more biodiversity than Forest A."
Biodiversity can simply be described as the variation that exist within an ecosystem whereby different organisms and species can be found in a particular habitat. The more varied the species that exist in an ecosystem are, the higher the biodiversity that exists.
Like the saying goes: "variety is the spice of life". The higher the biodiversity the better. Which means the more varied the species or organisms found in an habitat or ecosystem, the more functional the ecosystem would be.
In Forest A, only one tree species, which is Oak trees exist compared to Forest B that has different tree species.
Therefore, Forest B will have more biodiversity than Forest A.
