What are the similarities between evaporation and precipitation?
What are the similarities between evaporation and precipitation? Precipitation is comprised of rain and snow that falls to Earth’s surface from the clouds. Evaporation is the change in phase of liquid water from the Earth’s surface to water vapor in the atmosphere.

What is the angular displacement of the hour hand in 30 minutes?
What is the angular displacement of the hour hand in 30 minutes? Since the minute hand would make one rotation in 60 minutes, it would make 1/2 rotation in 30 minutes. What is the angular displacement of the minute hand in 15 minutes? Thus, the total angular displacement of the minute hand of the clock […]

Why do some hormones need to trigger a second messenger to activate a target cell?
Why do some hormones need to trigger a second messenger to activate a target cell? Binding of hormone to receptor initiates a series of events which leads to generation of so-called second messengers within the cell (the hormone is the first messenger). The second messengers then trigger a series of molecular interactions that alter the […]
