8th grade Science MAAP Review

What is a phenotype?

• The genetic makeup of an organism.

• The observable physical characteristics of an organism, such as hair color and eye color.

• The behavior patterns of an organism.

• The habitat in which an organism lives.

Where do earthquakes most likely occur?

• Along plate boundaries.

• In the center of tectonic plates.

• In areas with high humidity.

• Near volcanoes only.

What is the theory of plate tectonics?

• The theory that explains the movement of the Earth's lithosphere which is divided into tectonic plates.

• A theory that describes the formation of mountains due to volcanic activity.

• The concept that the Earth is flat and not spherical.

• A hypothesis about the origin of the universe and the Big Bang.

What is heredity?

• The process of evolution over generations.

• The passing of traits from parents to offspring.

• The study of genetic mutations.

• The influence of environment on traits.

What is the advantage of having different shaped beaks in birds?

• Different shaped beaks allow birds to eat the food readily available in their environment.

• Different shaped beaks help birds to fly faster.

• Different shaped beaks are used for attracting mates.

• Different shaped beaks provide better camouflage in the wild.

What is a gene pool?

• A gene pool is the total collection of genes and their alleles in a population.

• A gene pool is the set of all possible traits in an individual organism.

• A gene pool refers to the physical location of genes within a cell.

• A gene pool is the number of individuals in a population.

What is a genotype?

• A genotype is the physical appearance of an individual.

• A genotype is the genetic constitution of an individual, representing the alleles inherited from parents.

• A genotype refers to the environmental factors affecting an organism.

• A genotype is the sum of all observable traits of an organism.

What is a fossil?

• A fossil is the preserved remains or traces of a once-living organism.

• A fossil is a type of rock formed from volcanic activity.

• A fossil is a living organism that has not yet died.

• A fossil is a modern animal that has been genetically modified.

What is speciation?

• Speciation is the evolutionary process by which populations evolve to become distinct species.

• Speciation is the process of creating new habitats for existing species.

• Speciation refers to the extinction of a species due to environmental changes.

• Speciation is the migration of species to different geographical areas.

What is natural selection?

• A process where all organisms have an equal chance of survival

• A method of breeding plants for desirable traits

• The process by which organisms better adapted to their environment tend to survive and produce more offspring.

• A theory that suggests species do not change over time.
