Answer:
The pink substance underwent a phase change because its molecules were held together by weaker attractive forces compared to those of the green substance. The molecules in the pink substance moved rapidly enough to facilitate the phase change. In contrast, the molecules of the green substance experienced stronger attractive forces, meaning the energy supplied to them was insufficient to overcome these forces and prompt a phase change.
Mendel paired a dominant purple-flowered plant with a recessive white-flowered plant. The offspring in the F1 generation resulted in heterozygous purple-flowered plants (Pp). When two Pp plants are crossed in the F2 generation (Pp x Pp), the gametes produced are P and p. Among the offspring, you will find 3 purple-flowered plants and 1 white-flowered plant, generating a phenotypic ratio of 3:1, meaning one-quarter of the plants will have white petals. When converted to percentage, this translates to 25%.
The only "perch" that I found to be an animal is a type of fish. Perch is the common name for the fish categorized under the genus Perca. They are classified as freshwater gamefish.

3) Yellow perch<span> (</span>Perca flavescens) -<span> found in </span>the United States<span> and </span>Canada.
Common traits between rabbits and perch include:
1) a generally elongated and rounded body shape.
2) size variations depending on their breed (in rabbits) and species (in perch)
