Hi lovely! Here are your scientific questions that are testable:
Does the type of liquid affect how fast an ice cube melts?
Does changing the temperature of water affect the buoyancy of an egg?
Does the thickness of the wire affect the power of the circuit?
Hope I helped!
Answer:

The only "perch" I found that is an animal is a fish. The perch is the common name of the fish that is under the genus Perca. They are freshwater gamefish.
There are 3 species of perch are:
1) European perch<span> (</span>Perca fluviatilis<span>) - found in </span>Europe<span> and </span>Asia<span>.
2) </span> Balkhash perch<span> (</span>Perca schrenkii<span>) - found in </span>Kazakhstan, Uzbekistan<span>, and </span>China<span>.
3) </span> yellow perch<span> (</span>Perca flavescens) -<span> found in the </span>United States<span> and </span>Canada<span>.
The shared characteristics among rabbits and perch are:
1) general body type of long and round.
2) vary in sizes based on their breeds (rabbit) and species(perch)</span>
