Index Organisms Flashcards
Hydra circulatory system
No specialized transport
Uses water for transport
Materials are absorbed by diffusion and cyclosis
Earthwork digestive system
Tubelike digestion
Two openings
Pathway:
Mouth, esophagus,crop, gizzard, intestines, anus
Grasshopper respiration
Site of exchange: spiracies
Molecules are carried by: tracheal tubes
Hydra digestive system
Saclike digestion
One opening
No pathway
Hydra respiration
Site of exchange: at the cellular level; diffusion
Molecules are carried by: h2o
Earthworm circulatory system
Closed circulatory system
all materials dissolved in blood
Hemoglobin pigment used to carry dissolved oxygen and carbon dioxide
5 pairs of aortic arches
Grasshopper digestive system
Tubelike digestion
Two openings
Mouth, salivary glands, esophagus, crop, gizzard, gastric caeca, anus
Earthworm respiration
Site of exchange: moist skin
Molecules are carried by: capillaries near surface of skin; hemoglobin
Grasshopper circulatory system
Open circulatory system- blood typically collects in large cavities called sinuses
No hemoglobin
All materials move through pulsating aorta
Receptor proteins
Binds to a specific signal molecule and allows the cell to respond to the signal
Second messenger
A chemical made within the cell to relay a message that was received outside the cell
Ion Chanel
Closes
Signal molecule binds the receptor protein this causes the receptor protein to change shape the ion channel opens
I am for example passes through into the cell
The receptor protein activate an intermediate protein
The intermediate Pro Tien triggers an enzyme to create a new message molecule with and so the new message molecule will trigger some type of that with him
