Purple color is expressed in 3 out of the four because the law of dominance states that only one dominant gene needs to be present to express the trait. But there is one homozygous recessive that would be yellow because the genotype has two recessive genes.
Example: AA or Aa would be dominant because the capital letter represents the dominant gene

The plasma membrane is composed of the phospholipid bilayer. The phosphilipids have one head and two tails. The head is polar (hydrophilic) as the tail is non-polar (hydrophobic).
Plants need leaves, stems, and roots to do these jobs. But plants can have different leaf, stem, and root shapes depending on where they grow. The structures of plants are specially adapted to the environment in which they grow.
Answer:
The heat from the sun warms the water in the lake which evaporates and turns into water vapours. The water in the tree also rises into the atmosphere through a process, transpiration.
The water vapours rise into the atmosphere and forms clouds.
The water vapours in the clouds than condense into liquid water. Soon they'll get heavy and the water will fall down as rain, sleet, or snow.
Some of the rainwater sinks into the ground and is taken in by the roots of trees and plants.
This process keeps going on and on, and the water keeps shifting between the lake, tree and the sky.
