I need help on answering these questions.. if you can help me figure it out i would owe u big time!!
7b is the one we need to know, the others there as you may need to know what was aked of me before #7 6. Notice the spike in the concentration of oxygen around 300 million years ago. What biologic event coincides with this spike? The event that coincides with this spike is The Age of Giant Insects Insects don’t have lungs and rely on the diffusion of oxygen through their exoskeleton. What is the relationship here? 7a. If we compress the approximately 5,000 million years in history of the earth into the length of a day, how many years would each second of this day equal? To do this, you need to find out how many seconds are in a day. 60 sec x 60min x 24hr = sec min hour day day Then, divide that number of seconds per day into the 5,000 million years to get years per second 7b. At what time of this compressed day would Columbus have discovered the New World? Use your answer from 6a to find out how may seconds ago Columbus would have discovered the New World and subtract that number of seconds from 12 midnight to discover what time this happened. (I don't know if he menat to look at 7a, because it doesn't seem to make sense to me to look at 6a, but maybe I am worng.) |
