d. Stays in the same position
, 12)Which of the following correctly lists the cellular hierarchy from the simplest to most complex
structure?
a. Tissue, cell, organ, organ system, organism
b. Organism, organ system, organ, tissue, cell

What word describes the allele for green eyes?
a. Heterozygous
b. Dominan t c.
Recessive
