Characteristics of life
As autumn approaches, white-tailed deer begin to accumulate a layer of body fat. This is an
example of which characteristic of life?
maintaining homeostasis
metabolism
response to the environment
energy regulation
organization
The accumulation of body fat occurs in response to the seasonal change in temperature.

Characteristics of life II
Salmon live in both fresh water and salt water during their lives. They are born in in fresh water but
migrate out to marine waters for most of their life. Eventually, they return to the place they were
born in fresh water to spawn. Changing between fresh water and salt water affects the balance of
water in their body. Salmon have an internal control system called osmoregulation that restores the
balance by negative feedback. This is an example of which characteristic of life?
adaptation
reproduction and development
response to the environment
energy transformation
maintaining homeostasis
Many of the metabolic activities of an organism are involved in maintaining homeostasis, or an
internal environment that acts within a set of physiological boundaries. Since osmoregulation allows
the salmon to maintain an internal water balance, this is an example of maintaining homeostasis.

Genes
Which of the following statement(s) regarding genes is/are true? Select all that apply.
Genes are made up of DNA.
All cells in a multicellular organism contain the same set of genes.
Humans receive their DNA/genes from either their mother or their father but not both.
Variations in genes are the result of mutations.
All organisms such as roses, elephants and mushrooms have the same set of genes.
Genes are genetic instructions that are made up of DNA. While all organisms have DNA, they do not
all have the same genes. Human and other animals pass on their genes through their gametes.
Males pass their genes on through their sperm and females through their eggs. When an egg and
sperm unite, a fertilized egg is formed with a full set of genes (1/2 maternal and 1/2 paternal). As the
egg begins to split and form new cells, each new cell will receive a full copy of all the genes. What
makes one cell different from another is determined by which of the genes are turned on and which
are turned off. Variation in genes (like dimpled cheeks or smooth cheeks) is a result of mutations
