Cnidarian bodies are either in the polyp or medusa form with tentacles surrounding the mouth. what type of symmetry do they have a) radial b) asymmetrical c) bilateral

- Option a  radial symmetry

Explanation:-

Most of the organisms have can either of the two types of symmetry:-

1. Bilateral symmetry- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a single  plane.

For e.g if you cut the letter M from middle vertically then you have two equal halves.

2. Radial symmetry - A body is said to be radially symmetrical if  it can be divided into similar halves in any plane. This means that the organism has its body parts arranged around a central main axis.

The cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
