Explanation:
All substances of matter are made up of atoms. Atoms are the smallest indivisible particles that makes up matter.
Elements, molecules, compounds and mixtures are all combinations of different atoms.
An atom in itself is made up three important fundamental sub-atomic particles which are protons, neutrons and electrons.
From the video, any form of matter seen is made up of atom. Matter is anything that has weight and occupies space.

Answer:
<h3>plant has cell wall but animals don't have </h3>
Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
Answer: D) Polygenic
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
