What advantage does the exoskeleton give to both arthropods and molluscs?
they help retain moisture in terrestrial habitats
200
How do fungi "eat?"
They secrete digestive enzymes and then absorb the nutrients
200
Which body plan has distinct dorsal and ventral sides?
Bilateral
200
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
200
The squids are a type of ?
Mollusc and a cephalopod
200
What is the function of the water vascular system in echinoderms?
locomotion and feeding
300
Is this a coenocytic fungus?
yes

Sessile animals are best described as:
Attached and stationary
300
In the following diagram, which form is the medusa form?

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
400
What is similar between fungi and insects?
They both have chitin
400
Diploblastic animals lack which germ layer?
Mesoderm
400
Which type of symmetry do Cnidarians (jellies) exhibit?
Radial
400
What are Ecdysozoans? (what are their characteristics?)
protostome/deuterostome?
Symmetry?
Skeleton?
protostome, bilateral, and hard cuticle or outer coating
400
What is the atypical strategy that Bdelloid Rotifers use to create greater genetic variation?
They can absorb DNA from their environment when they rehydrate
500
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
500
In triploblastic animals, the mesoderm gives rise to:
muscles and most organs
500
What advantage do free-swimming larvae confer on reef-building corals?
allowing reef-building corals to expand their populations into new habitats
500
How do ecdysozoans grow?
They must molt, or shed their cuticle
500
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

What is the reproductive strategy in yeast?
they pinch off "bud cells" that are smaller than the parent cell
600
Indeterminate cleavage can result in:
identical twins in humans

What do the Hox or homeobox genes do?
they encode for the different body plans

The coelom forms from mesodermal pockets pinching off the archenteron in:
Deuterostomes

What are the differences between centipedes and millipedes?
millipedes have 2 legs per body segment, centipedes have 1 leg per body segment, centipedes have poison front claws
