What does hierarchical classification mean?
Living things are grouped into large categories that are divided into smaller groups.
An organism that carries out all life processes in one cell belongs to which kingdom?
Monera
What does it mean when an organism is well adapted?
Its traits help it survive and reproduce in its environment.
Sexual reproduction increases genetic variation; asexual reproduction leads to what?
Rapid population growth
When an intermediate/different trait appears, what type of dominance is this?
Incomplete dominance
How does a family compare to genus, order, class, and phylum in similarity?
A family is less alike than a genus, but more alike than order, class, or phylum.
Which classification level contains more organisms: genus or family?
A family contains more organisms than a genus.
What physical feature is most important when classifying plants?

What structure is the genetic material that makes up chromosomes?
DNA
What is a gene?
A section of DNA that codes for a trait.

Endangered
Construction of housing on grassland is an example of what?
Habitat destruction
A species feeding on only one plant is an example of what?
Overspecialization.
What is fertilization outside the body called?
In-Vitro Fertizilation
Protecting animals in national parks is an example of what?
In-situ conservation.
Protecting endangered plants and animals outside their natural habitats in managed, artificial environments like zoos, aquariums, botanical gardens, and seed banks, aiming to save species from extinction, study them, or reintroduce them later into the wild.
Ex-situ conservation.
What strategy focuses on restoring species populations and involves returning land to its natural state?
Restoration of ecosystems and species.
