Explanation:
The changes that matter undergoes can be attributed to their properties.
Physical change is one of such.
- A physical change is one that alters the physical properties of matter especially its form and state.
- The physical properties of matter tells us everything about what a substance is when no change is occurring to its constituents.
- In most cases physical changes are usually reversible.
- Examples are boiling, melting, freezing, condensation, sublimation, magnetization of metals etc.
- Physical changes leads to the production of no new kinds of matter.
- They involve no mass change and requires little to no energy.

Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).
<h3>
What are homologous structures?</h3>
A physical trait that distinguishes two or more species, such as a complicated bone structure or a body plan, may have been passed down from a common ancestor.
A common ancestor's evolutionary history causes physical characteristics to be homologous.
Sometimes, structures in an organism are similar to crucial structures in other animals, but they no longer serve the primary ancestral role. Vestigial structures are these structures, which are frequently scaled down.
Therefore, Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).

A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids, which the body can't make itself. Fat helps the body absorb vitamins A, D and E. These vitamins are fat-soluble, meaning they can only be absorbed with the help of fats.
