As early vertebrates transitioned from an aquatic lifestyle to terrestrial habits, major changes in structural and physiological characteristics facilitated their survival and expansion. It is likely that some of these traits are a result of: a) changes in developmentally important genes, as in evo-devo the ability of some cells to incorporate environmental DNA, or eDNA, into its genome b) new Hox genes that reverse some steps in development c) transcription factors that originate outside of the developing embryo d) new interactions between cytoplasmic determinants and the nucleus

Clues to ecological principles are given in numerous passages of the bible. a bible study of ecology actually opens the doors to better understanding of god's love and concern for the earth. use a concordance to locate bible passages associated with words concerning our stewardship of the earth. you may use a dictionary to find synonyms for these words: dominion replenish subdue judgment stewardship find each of the passages using these words related to principles of ecology. list all passages by quote, book, chapter, and verse under each word. use your own interpretation to rewrite what you think each verse is saying. after your discussion of each of these words, ask one other person to explain his understanding of the word and a related verse without any hints. summarize what he tells you. a concluding paragraph for each of the words should be written noting similarities and differences between your interpretation and that of each person consulted.

On a backpacking trip, kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 calories. at the school track, janelle runs the 100-meter sprint in 13.5 seconds, burning 10 calories. afterward, janelle’s leg muscles are aching and she is breathing hard, while kenny maintains normal breathing all day, even though he burns 400 times more calories than janelle. which two statements offer the best explanation for this phenomenon? a. if the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt." b. aerobic cellular respiration produces more energy, but its use is limited because of lactic acid buildup in the muscles and the resulting "oxygen debt." c. after about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce atp, resulting in "oxygen debt." d. the rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
