Sponges live their lives attached to the sea floor or onto rocks that are under water. They have no organs, so they feed by allowing nutrient-rich water to flow through them. Based on the diagram of a sponge cell, what best explains if sponges are considered animals or plants?
Sponge cells do not have cell walls, so they must be animals.
Sponge cells do not have mitochondria, so they must be plants.
Sponge cells do not have a nucleus, so they must be plants.
Sponge cells do not have vacuoles, so they must be animals.

Scientists once thought that living things could be generated from non-living things (theory of spontaneous generation). What happened that allowed this idea to be removed from science?
Scientists discussed among themselves and the majority agreed on removing the principle
Scientists read a book saying that the principle was not true, so they removed it
Scientists did not believe on that, so they just decided to remove the principle
Scientists (for example Redi and Pasteur)tested new hypothesis conducting experiments and got new results
Which principle of the original cell theory was removed due to new research and evidence?
All cells come from pre-existing cells.
Cells are the basic structural and functional units of life.
All living things are made of cells.
Cells form through spontaneous generation.
