You purchase two identical houseplants and place them side by side on your windowsill. you water both plants equally. you leave one plant, plant a, alone, but you inject florigen into the cells of the shoot apical meristem of plant b. what would you expect to occur? both plants a and b will produce flowers at the same time, but plant b will have more of them. once the flower is gone, the apical meristem will develop again, and plant b will continue to grow from that stem. while plant b is flowering, its leaves will stop growing, because florigen inhibits leaf meristems. in subsequent years, plant b will only generate flowers in the same place. the shoot apical meristem of plant b will develop into a flower.

How can you increase the strength of an electromagnet?

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
