Body structures that have similar shape and number of bones are examples of
A. homologous
B. analogous
Structures that have the same function but do not have a common ancestor are
A. homologous
B. analogous
The forlimbs of humans, dogs, whales and bats have similar bone structures. These structures are examples of
homologous structures
analagous structures
The forelimbs of humans, dogs, whales and bats are similar in structure. Do the forelimbs of humans, dogs, whales, and bats indicate a common ancestor?
yes
no
The wings of bats and birds are an example of
homologous structures
analogous structures
The wings of bats and birds have the same function but the structure of the bats are very different. Wings are example of
homologous
analogous
The function of Cytochrome C is
growth and development
releasing energy from food
finding a mate
making identical cell copies
Why is Cytochrome C used by scientists?
it is used for genetic variation
it is used for flight
it is a large nuclotide and easy to see without a microscope
tend to be shared by many organisms because they govern basic survival functions
In general if two species share many animo acids sequences together are they closely related?
yes
no
According to the number of differences in Cytochrome C which organism is most closely related to the bat?
A. bird
B. dog
C. human
D. whale
According to the number of differences in Cytochrome C which organism is least closley related to bats?
