Read the passage and examine the photos. Then, suggest two reasons that scientists think developing pollen grains made vascular plants the most successful plants that live on land.
PASSAGE:
These mosses are nonvascular plants that grow closely packed together in moist places. The sperm they produce for sexual reproduction must swim to a nearby plant that has an egg that the sperm may fertilize. Seed plants, such as these conifers, are vascular plants that live in both moist and dry places. For sexual reproduction, conifers produce pollen grains that contain sperm that cannot swim. Conifers produce massive amounts of pollen grains that can be carried by wind.โ

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
