2
Gregor Mendel contributed to the study of biology by the careful study of
heredity
pedigrees
bacteria
mutations
3
What happens in the last stage of mitosis?
Chromosomes line up along the middle of the cell
Attached chromatids are pulled apart by spindle fibers
Chromosomes reach opposite ends of the cell
Chromatin condenses to form chromosomes
4

will have large leaves
resulted from sexual reproduction
resulted from asexual reproduction
will develop many seeds
5
Organisms that reproduce asexually generally have offspring that are
genetically identical
genetically varied
unicellular
multicellular
6
As a flower ages, its leaves grow. What process is responsible for the growth of the leaves?
release of oxygen
transportation of nutrients
absorption of carbon dioxide
division of plant cells
7
