Allosteric Site
the site where the signal molecule binds to the enzyme surface
structural formula
A notation which represents both atoms and bonding.
Bilateral symmetry
characterizing a body form with a central longitudinal plane that divides the body into 2 equal but opposite halves. This type of animal has a DORSAL(top) side, VENTRAL(bottom) side, left and right side, and an ANTERIOR(head) end with a mouth and a POSTERIOR(tail)end.

What does a protein do?

Animals balance the gain and loss of water and solutes
Aerobic Respiration
Respiration in the presence of oxygen. Producing 36 ATP.
active immunity
immunity in an organism resulting from its own production of antibody or lymphocytes.
van helmont
measured plants water intake and mass increase. concluded that trees gain most of their mass from water.
active site
the place on the enzyme that causes the substrate to change
Active Transport
When ATP is consumed by a cell transporting items in or out of the cell membrane
Food Chain
A simple model that scientists use to show how matter and energy move through an ecosysytem.

what is the growth in circumference in a plants?
secondary growth
What characteristic would all protobionts have had in common?
surrounding membrane or membrane like structure
What is character displacement?
Any change in morphology, niche or behavior resulting in competition
Sickle Cell Anemia

diploid (somatic) cell
2n; has two homologous copies of each chromosome
what is the quaternary structure?
PS, more than one polypeptide chain
external respiration, the exchange of gases (oxygen and carbon dioxide) between air and bloodtransport of gases to and from the lungs and other tissuesinternal respiration, the exchange of gases between the blood and tissue fluid
major functions of the respiratory tract
describe the characteristics of the 3 domains and 6 kingdoms
3 domains: Archaeans, Eurkarya, bacteria
kingdoms: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia
Archaea and bacteria contain prokaryotic organisms and do not have a membrane bound nucleus
Eukaryaians have a nucleus

four functions of the respiratory system:
1. gas exchange (o2 and co2)
2. balance of pH of blood
3. sense of smell, speech
4. breathing helps with blood and lymph flow

(a): all body cells except the reproductive cells.
What is the difference between open and closed circulation?
- In open systems: Heart pumps blood into body cavities where tissue is surrounded by blood. Blood is at low pressure after it leaves the blood vessels- Closed: Blood is confined to tubes of blood vessels, while valves prevent the backflow of blood.
