Explain the need for a constant supply of inorganic carbon dioxide.A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 µmol, and Groups 3 and 4 were exposed to 500 µmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below.

- Determining the surface area of biological materials is important for calculation and/or modeling of transpiration, respiration rate, soil nutrient uptake, cardiac output, chemotherapy dosage, heat transfer, etc. Using the tables from "Biology for Engineers" by Arthur Johnson (uploaded to Canvas in the Physical Properties of Biomaterials Tables file) and equations discussed in class, calculate the surface area of a Hereford bull (1106.7 lb) and compare it to that of the tallest man in U.S. history (8.0 ft 11.0 in tall and 439.0 lb according to the Guinness World Records). Quantify the comparison of surface areas rather than simply saying one is greater than the other.
