Some cells are covered in cilia, which are tiny hair-like structures. what are two functions of cilia? movement and obtaining food movement and grooming obtaining food and expelling waste grooming and expelling waste

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the median of the data is 4.5.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
