Metabolic Rate (MR) and Oxygen Consumption:
1. Oxygen Consumption per Hour:
a. MR = Oxygen consumed (mL) per hour.
2. Divide by Weight:
a. Formula:
MR (mL/hour/gram)=Oxygen Consumption (mL/hour)Weight (grams)\text{MR
(mL/hour/gram)} = \frac{\text{Oxygen Consumption (mL/hour)}}{\text{Weight
(grams)}}
MR (mL/hour/gram)=Weight (grams)Oxygen Consumption (mL/hour)
b. Example: 2.4 mL (oxygen consumed) / 0.3 grams (weight) = 8
mL/hour/gram.
3. MR Unit:
a. mL/hour/gram is the unit for metabolic rate.
Ectotherms vs. Endotherms:
Ectotherms:
oAs temperature increases, metabolic rate increases.
Endotherms:
oAs temperature increases, metabolic rate decreases.
Photosynthesis:
1. BRB (Bromothymol Blue):
a. A pH indicator used to show changes in pH during photosynthesis.
2. Effect of Seltzer:
a. Adding seltzer to the water causes an acidic pH, turning the water
yellow/green.
3. Photosynthesis Process:
