The vapor rises until it reaches a low enough temperature and pressure to condense water vapor into water droplets and form a cloud. When vapor condenses into liquid or solid particles, it loses some of its energy to the air.

Explanation:
Vertebrate animals - representing the subphylum Craniates, as its name implies, are those animals that have as their main characteristic the spine. This structure is responsible for shaping, balancing and protecting the nerve cord.

A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
