There are sutures (lines of fusion between bones) associated with cranial (skull) bones.
The process where a specie develops and evolves into new many species is termed as speciation. Macroevolution explores the mechanism of speciation where organisms across biological populations evolve as distinct population.
There are many causes to speciation, a) geographic isolation, b) gene flow reduction, and c) reproductive isolation.
It’s C ) Mitochondria-makes energy
The total energy from an isolated system is constant; energy can be changed from one form to another, but can't be created or destroyed.
Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.
