100

The smallest unit of an organism.

What is a cell?

100

a different form or version of something.

What is variation?

100

The passage of genetic instructions from one generation to the next generation.

What is heredity?

100

Allows organisms to continue their species by way of producing offspring.

What is the reproductive system?

100

This type of cell genetic material is not bound within a nucleus.

What is a prokaryotic cell?

200

A combination of cells that have similar structure and function

What is tissue?

200

process by which organisms that inherit helpful traits tend to reproduce more successfully than other organisms do.

What is natural selection?

200

Segment of DNA found on the chromosome; determines the inheritance of a particular trait. 

What are genes?

200

This system holds organs in place, provide structural support for the body and its muscles, stores minerals and contains materials to make new blood cells.

What is the skeletal system?

200

Determines who will have blue, brown, or green eyes, straight or curly hair, and even what blood type a person may have.

What is heredity?

300

An individual living thing.


What is an organism?

300

a change in structure or habits (behavior), often hereditary, by which an organism improves its condition in relationship to its environment

What is adaptation?

300

A trait developed through interaction in their environment.

What is acquired trait?

300

This system filters water and fluids from the blood while also collecting waste.

What is the excretory system?

300

Predisposition to a medical condition such as cancer, heart disease, sickle cell anemia or diabetes.

What is an inherited trait?

400

A group of organs that work together to perform a certain task.

What is an organ system?

400

making deliberate crosses of plants or mating of animals, so the offspring will have a desired characteristic derived from one of the parents.

What is selective breeding?

400

Made of DNA located in the nucleus; contains genetic information needed to carry out cell functions and make new cells.

What is chromosome?

400

This system converts food into simpler substances for the body to absorb its nutrients.

What is the digestive system?

400

The outward physical appearance of an organism.

What is phenotype?

500

A collection of tissues joined in structural unit to serve a common function.

What is an organ?

500

a tool used to identify species of organisms using opposing observable characteristics.

What is dichotomous key?

500

One pair of genes that determine a specific trait. 

What is an allele?

500

This system continuously receives communication with the external environment.

What is the integumentary system?

500

A change in the DNA or chromosome of an organism.

What is a mutation?
