The main functions of Mitosis are growth and repair.
Cells must perform this to where they can grow or repair. Some cells you cannot regrow nor repair because they are already fully mature, you'll just halve to take care of them.
HOPE THIS HELPS! ^_^
Answer: A. Increase in temperature
Coastal upwelling is the process in which the deep water rises above the top most water level as the wind pushes water offshore. Nutrients which are present in the bottom layer get available to organisms living in the uppermost layer. The deeper water lacks oxygen because the decomposition of organic matter at the bottom of the water body consumes up available oxygen. Also, because of these water layer turnover will result in thermocline: temperature variation among the layers of water. Bottom layer water because of such decomposition processes will have more temperature when this water rises in the upper layer due to upwelling this will increase the temperature of the upper layer.
D, because one of the advantages of sexual reproduction is diverse offspring.
