Measurement
Why is scientific notation necessary in science?
There are very big (e.g.astronomy) and very small numbers (e.g.biology, chemistry, and physics) that are tedious to write.
What category of organisms is solely prokaryotic?
Bacteria
What scale is based on the H+ ion?
pH scale
0-6 lots of H+ ions (acid)
7 neutral
8-11 little H+ ions (Base)
What type of tissue lines cavities?
epithelial tissue
What are nociceptors?
pain receptors in the dermis
How many significant figures are in .000206700 ?
6
What type of cell transport happens in the kidney and nerves?
active transport- Na+/K+ pump-going less to more with energy
How is C-14 different from C-12?
C-12 is on the Periodic table and is an element and is not radioactive.
C-14 is an isotope of C-12 and has 2 more neutrons and is radioactive.
Name two types of cells found in nervous tissue.
neurons and neuroglia
What is the difference between sebaceous and sudoiferous glands in the skin?
sebaceous- produce oil
sudoiferous-produce sweat
How many significant figures are in 6,025,000 ?

What organelles in the cell do cellular respiration, photosynthesis and protein synthesis?
mitochondrion-cellular respiration
chloroplast-photosynthesis
ribosome- protein synthesis
Explain the type of bonding that two nonmetals such as H and O have.
It is covalent bonding where the electrons are shared so that both elements have filled valence shells.
What are 3 types of muscle tissue?

meter (m), liter (L), gram (g), degrees Celsius (degrees C)
Why are humans put into the animal kingdom wrt cellular structure?
no cell wall and eukaryotic
What type of reaction(s) is/are cellular respiration?
It is decomposition and combustion and a series of redox reactions
What are 3 types of special connective tissue?
