What advantage does the exoskeleton give to both arthropods and molluscs?
they help retain moisture in terrestrial habitats
How do fungi "eat?"
They secrete digestive enzymes and then absorb the nutrients
Which body plan has distinct dorsal and ventral sides?
Bilateral
Why are sponges not considered to have tissues even though they have different cell types?
Their different cell types do not work together as functional units
The squids are a type of ?

What is the function of the water vascular system in echinoderms?
locomotion and feeding

Is this a coenocytic fungus?
yes

While sampling marine plankton in a lab, a student encounters large numbers of fertilized eggs. The student rears some of the eggs in the laboratory for further study and finds that the blastopore becomes the mouth. The embryo develops into a trochophore larva and eventually has a coelom and a hemocoel. To which group of organisms did these eggs likely belong?
molluscs have both a coelom and a hemocoel
What is similar between fungi and insects?
They both have chitin
Diploblastic animals lack which germ layer?
Mesoderm
Which type of symmetry do Cnidarians (jellies) exhibit?
Radial
What are Ecdysozoans? (what are their characteristics?)
protostome/deuterostome?
Symmetry?
Skeleton?
protostome, bilateral, and hard cuticle or outer coating
What is the atypical strategy that Bdelloid Rotifers use to create greater genetic variation?
They can absorb DNA from their environment when they rehydrate
How are mycorrhizal fungi more efficient than plants at acquiring mineral nutrition from the soil
Fungi secrete extracellular enzymes that can break down large molecules
In triploblastic animals, the mesoderm gives rise to:
muscles and most organs
What advantage do free-swimming larvae confer on reef-building corals?
allowing reef-building corals to expand their populations into new habitats
How do ecdysozoans grow?
They must molt, or shed their cuticle
Which of these is NOT a function of the body cavity in ALL animals?
A) The internal fluid can cushion the organs inside it
B) The internal fluid can act like a “hydrostatic skeleton” so that muscles can move against it
C) A pocket for storage of accessories
D) Enables the growth and movement of internal organs independent of the body wall.
C) A pocket for storage of accessories

they pinch off "bud cells" that are smaller than the parent cell
Indeterminate cleavage can result in:
identical twins in humans
What are three ways to increase the surface area to volume ratio?
flattening, branching, folding, and projections
The heartworms that can accumulate within the hearts of dogs and other mammals have a hemocoel, an alimentary canal, and an outer covering that is occasionally shed. To which phylum does the heartworm belong?

millipedes have 2 legs per body segment, centipedes have 1 leg per body segment, centipedes have poison front claws
Describe the relationship between a fungus and a photosynthetic microorganism in a lichen?
the fungus provides the photosynthetic microorganism a suitable environment for growth
What does the letter K represent?
Karyogamy
What is the primary difference between a coelom and a hemocoel?
their developmental origin
Sheep liver flukes (a parasitic flatworm) have which of the following characteristics? (symmetry, tissues, digestive tract)

How would you design an experiment (using an antifungal substance) to allow a researcher to determine the effect of mycorrhizae on plant growth?
measure and compare the growth of two different plants, one of which has had antifungal substances added to it and one that has not
