things? - ANSWERS✔-Made up of one or more cells: carries out reproduction:
processes genetic and environmental information.
\.All living things are made up of many cells? T/F - ANSWERS✔-False
\.What is not true about all living things? - ANSWERS✔-They don't all need
oxygen, they don't all breathe, they don't all move, and they don't all have a
nucleus.
\.All eukaryotic cells have a cell membrane? T/F - ANSWERS✔-True, all cells have a
cell membrane.
\.All eukaryotic cells have a cell wall? T/F - ANSWERS✔-False, animal cells and
some protist cells do not have a cell wall.
\.Variation is necessary for natural selection to occur? T/F - ANSWERS✔-True
,\.What best describes the difference between prokaryotes and eukaryotes? -
ANSWERS✔-Eukaryotic cells have a membrane-bound nucleus: prokaryotic cells
do not.
\.What can be used to decide whether two populations are the same or different
species? - ANSWERS✔-The morphological species concept, the biological species
concept and the phylogenetic species concept
\.A population is a group of individuals of the same species. According to the
theory of natural selection, what is likely to happen to a population when a
change occurs in its environment (for example, the amount of rainfall decreases or
the temperature increases)? - ANSWERS✔-The individuals that have traits better
suited to the changed environment would be more likely to survive and reproduce
than those with less suitable traits.

Others, such as a chicken and an oak tree, have fewer similarities. What is TRUE
about the ancestors of these organisms? - ANSWERS✔-Chimpanzees, humans,
chickens, and oak trees all share an ancient common ancestor.
\.What is true about living species and extinct species? - ANSWERS✔-A species
living today and an extinct species could share a common ancestor that lived a
very long time ago, even if the two species have few similarities

movement
\.Which of the following would be a possible explanation for the molecular origin
of a new allele in a population of mice? - ANSWERS✔-DNA polymerase skipped
three nucleotides in a gamete-producing cell during replication causing a
mutation before meiosis
\.Which of the following describes a major difference between eukaryotes and
prokaryotes? - ANSWERS✔-Eukaryotic cells have a membrane-bound nucleus;
prokaryotic cells do not
\.How do you tell which animals are more closely related? - ANSWERS✔-When
they share a common ancestor more recently
