REGENTS BIOLOGY MIDTERM ANSWER SHEET A B
43 X 10 = 430x C
6 protons
2 e- in the first shell; 4 e- in the second shell
4 e- 9.
B – you don’t use energy for diffusion! D
D – inorganic compounds like water and carbon dioxide
C – because they are using oxygen to do cellular respiration
Both have a cell wall, both are heterotrophs, both can be single-celled (but not all!), etc.
Use several containers for each solution, not just one; add one type of solution to each set of containers, and keep one with distilled water as a control; keep temperature, pressure, humidity, light, etc. constant; record how many eggs in each setup hatch; organize the data in a chart or graph; the setup with the most eggs that hatch would be the best.
SEE YOUR NOTES ON ORGANELLES!
Iodine turns blue-black in the presence of starch.
D -- Proteins CAN be used for energy!
A protist would use pinocytosis or phagocytosis to engulf a food particle.
DNA evidence, colors, use things that are objective, not subjective (open to discussion).

2. B
Process 2 is digestion. The enzymes of cellular respiration can only break down simple sugars like glucose, not complex sugars, like starch.
Cellular respiration
ATP
It’s volume increases faster than its surface area.
Shape – must fit in with the substrate, pH – can change the shape, temperature – can change the shape. C
Autotroph – plants, green bacteria; heterotroph – fungus, protist, animal, etc. A
Glycolysis – breaks glucose into two pyruvates, creates a lil’ ATP; Krebs – breaks down pyruvate to make lots of reduced compounds/electron carriers; ETC – uses electrons from electron carriers to create a proton gradient to make lots-o-ATP.
Make proteins
Protection, control of what goes in/out, regulation, etc.
Protection, support
Protist cells have no cell walls, bacterial and fungal cells do, all are heterotrophs, etc.
Spore
