Definition:◦ Science is a process of inquiry◦ Using the knowledge of

scientific experiments to explain how we understand something Example: X-Ray Diffraction

DNA Structure

Definition:◦ Living things have changed through time ◦ Diversity can be seen in all things, yet there

seems to be a pattern of unity Example: Numbers and types of plant life is

extensive, yet the fossil record shows a common “body plan”

Definition: (Heredity)◦ Passing traits from generation

to generation allowing a continuous flow of INFORMATION, yet allowing for new variations to arise Example: Meiosis produces

new gametes with same amount of DNA, but each cells has variable forms of information

Definition:◦ How energy is used in various processes◦ How energy is generated by living organisms

Example: 10% Energy Rule (flow from producer consumer decomposer)

Definition: ◦ The specific structure of an object allows for

job efficiency Example: RBC’s are bi-concave disks to

allow them to pick up[ oxygen more efficiently (lacks nucleus too)

Definition:◦ aka Homeostasis◦ Dealing with the hormonal control of

processes Example: Body Temperature

Hot: Sweat Cold: Shiver

Definition:◦ A variety of processes,

organisms, & body parts are dependent on one another

◦ Actions in one locale produce an effect elsewhere Example: Food Webs

Definition:◦ Technology has led to advancements in

society (in this case, medically/biologically related) Example: The ability to mass produce

insulin by using bacteria have lowered the drug cost
