Answer: sexual reproduction.

Explanation: In asexual reproduction there is no exchange of genetic characteristics due to the lack of fusion of gametes(haploid). Thus there is practically no variation in specie.

But in sexual reproduction there is exchange of genetic characteristics resulting from the fusion of haploid gametes hence there is variation and great diversity.

Explain how the water cycling through the atmosphere and hydrosphere affects weather and climate. Contrast weather and climate.
masya89 [10]
First, weather is the atmospheric condition occurring over a short period of time in a relatively small location. Climate, on the other hand, is the overall environmental condition over extended periods of time. Next, the water cycle is when water from the surface evaporates as water vapor under high temperatures and condenses in the atmosphere under lower temperatures and precipitates back to the surface. In the event that water evaporates more than it condenses then the weather will be warm to hot, the ground will be relatively dry, and drought over extender periods of time may ensue. On the other hand, if water condenses and precipitates more than it evaporates, then there will be a rainy season, and may extremely lead to landslides and floods.
