NGSS.MS-LS4-4

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

NGSS.MS-LS4-4

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation

Tags

NGSS.MS-LS4-4

Body parts of organisms that are the same in structure and position but different in function.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

NGSS.MS-LS4-2

Body parts that function like each other, but are different in structure.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

NGSS.MS-LS4-2

Body parts that have lost their original function.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

Organisms with these structures are believed to be closely related.

• analogous structures
• homologous structures 
• mutated DNA
• gills

NGSS.MS-LS4-2

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding

NGSS.MS-LS4-4

What is it called when humans decide which traits of an organism are the most desirable and only allow those organisms with the specific, desired traits to breed.

• biological evolution
• evolution by natural selection
• artificial selection
• inbreeding
