Natural Selection & Selective Breeding

What is natural selection?

• a living individual that can carry out life processes

• Process by which an organism that better adapts to their environment survive and reproduce

• Process by which a community better adapts to their environment to give traits to one another within their generation.

• the time between when an organism is born and when they reproduce

What does the term Generation mean?

• the time between when an organism is born and when they reproduce

• a living individual that can carry out life processes.

• a total of all biotic (living) and abiotic (non-living) things.

• A change in the DNA sequence.

What is a mutation?

• a total of all biotic and abiotic things

• the time between when an organism is born and when they reproduce

• A change in the DNA sequence.

• an ancestor that two or more descendents have in common.

What is Heredity?

• the passing of traits from one generation to the another from parent to offspring.

• the passing of traits from one generation to the parent and the common ancestor.

• the passing of characteristics from one generation to another from offspring to the parent.

Students were discussing how giraffes were shaped by their environment and how the environment was shaped by giraffes. Which statement is most likely correct?

• Student A: Giraffes had a random mutation that made their necks super long and able to eat tall trees.

• Student B: Trees grew taller to try and escape giraffes, while giraffes always had long necks

• Student C: Giraffes and trees grew together, trees growing taller and giraffe neck growing longer as ways to survive and reproduce.
