In tropical rainforests, birds have evolved to eat the brightly-colored fruits. The fruits have evolved their attractive color so the birds will eat them and spread the fruits’ seeds. What might happen if another species of bird started eating the same fruits? Explain two different ways in which the interaction of birds and fruit might affect each other's evolution

Several mountains together form a mountain . a few of these combined form a mountain system. several systems combined form a mountain , which can stretch thousands of miles in length.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
