6.Which species on the following cladogram has the most ar DNA se-

7.Largemouth bass have recently been introduced into ponds that
previously did not contain any large, predatory fish. Which adaptation would
help the existing population of small, prey species of fish avoid predation
from the largemouth bass?: Faster average swim speed
8.Western spadefoot toads breed and deposit their fertilized eggs in
small, often short-lived ponds. The tadpoles grow in the ponds for a
period of time before undergoing a metamorphosis into an adult frog. One
unusual
characteristic of spadefoot tadpoles is the ability to change body form during
development. Normally most tadpoles are herbivorous and feed on plant
material. However, when conditions in the ponds suggest they are beginning
to dry up (e.g., an increase in water temperature or concentration of organic
waste), a small percentage of individuals in the population undergo a
dramatic change in body form and habit and begin to eat their competitors.
This ability is considered to be advantageous as it both reduces the number
of competi- tors in the pond and speeds up the rate of development of the
