Distinctive characteristics or features that make something different from anything else
What is variation?
100
Occurs when only one parent supplies genetic information to the offspring
What is asexual reproduction?
100
The number and variety of organisms
What is biological diversity?
100
the extinction of a species in certain locales
What is extirpation?
100
a cell first duplicates its contents, including its nucleus and other organelles. After the amoeba divides, each new cell has a copy of the genetic material, creating identical offspring.
What is binary fission?
200
The process of a species evolving into a variety of of similar yet separate species.
What is speciation?
200
Cutting from a parent stem to produce new plants that are exact copies
What is cloning?
200
a type of plant or animal
What is different species?
200
A species that helps indicate environmental change.
What is a bioindicator species?
200
When two parents supply genetic material to the offspring
What is sexual reproduction?
300
A measurement that compares the diversity of species in an area with the total number of organisms in the same area.
What is the diversity index?
300
when genetic characteristics have a limited number of possibilities.
What is discrete variation?
300
The reason one species may win in a competition over food or resources in the same general area.
What is variation among species?
300
Zoos and seed banks
What is humanity trying to preserve biological diversity in plants and animals?

Changes in DNA caused by factors in the environment and random errors.
What is mutations?
400
the role or characteristic activity that is undertaken by an organism in an ecosystem

What is meristem?
500
An interaction between organisms of different species living in close proximity to each other in a relationship that lasts over time
What is a symbiotic relationship?
500
Moving pieces of DNA from one cell to another
What is genetic engineering?
