Genetic variation describes the genetic differences among individuals of the same species that are naturally occurring. <span>Each genotype within a population usually has different degrees of fitness to an environment. Mating between same species with favored genes guarantees survival of the population in their chosen environment. As the environment changes, the mating behavior between species may again change resulting to a different gene pool to guarantee survival. </span>
The sun contains about 99.9 percent of the mass of the solar system.
X = about 1 or x = about -2
9x^2 + 12x - 24 is standard form: ax^2 + bx + c
quadratic formula: x = (-b ± <span>√(b^2 - 4ac)) / 2a
x = -12 </span>± <span>√(12^2 - 4(9)(-24)) / 2(9)

Answer:
Distinguishing between Similar Traits
Similar traits can be either homologous structures that share an embryonic origin or analogous structures that share a function.
LEARNING OBJECTIVES
Explain the difference between homologous and analogous structures
KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
Answer:
Erosion is the cause for most canyons and caves it’s caused by water or just air beating against rocks
