Using a microscope in the science lab, Jill observed two unknown cell: Cell 1 and Cell 2. Cell 1 she identified as a plant cell and Cell 2 as an animal
cell. Her teacher told her she identified the cells correctly. What did Jill most
likely observe to correctly identify the cells?
A. Cell 2 had a cell membrane and Cell 1 did not.
B. Cell 1 had a cell wall and Cell 2 did not.
C. Cell 2 had a chloroplast and Cell 1 did not.
D. Cell 1 had a nucleus and Cell 2 did not.

Which scientific design has both practical limitations and limitations due to scale? studying the effect of bleach on the growth of mold spores exposing cultures of duckweed to different intensities of light observing the replication of dna molecules with a hand lens using colored marbles to model a cross between two colors of rabbits

Acell goes through cellular respiration and produces atp which it then uses to move a molecule across the cell membrane. how does the energy in the original glucose molecule change during this process? (2 points)
