In examining a picture of a cell taken with an electron microscope, a student observes that the cell has a nucleus and a cell membrane, but not a cell wall. The student can correctly conclude that the cell probably comes from: A. an animal
B. a fungus
C. a seaweed
D. a plant

D. an animal

Explanation:

fungus has a form of cell wall

seaweed is a plant so it contains a cell wall

and all plants have a cell wall

animal cell only have a membrane

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).
