In all cnidarians, the gastrovascular cavity is a digestive system
complete with a mouth and an anus
incomplete with only a mouth
incomplete with one opening acting as the mouth and anus

The medusa stage of anthozoans
Is free swimming, carried by ocean currents
Is capable of moving against ocean currents
Is free swimming, but too heavy to be moved great distances

The symbiotic relationship shared between corals and zooxanthellae is referred to as
Commensalism
Mutualism
Parasitism
Predation
What is symbiosis?
A relationship where only one organism benefits
A relationship where both organisms benefit
A relationship shared between two different organisms
A relationship where one organism preys on another
Name this body type.
Medusa

When corals expel their zooxanthellae, what happens to their colour?
Nothing, the zooxanthellae do not contribute to the colour scheme of corals
The corals become slightly discoloured, moreso attributed to shock rather than the loss of zooxanthellae
The corals brighten in colour, as they receive more nutrients from filter-feeding planktons then living with corals
The colouration disappears, leaving the coral temporarily colourless until the zooxanthellae return

Why would corals need to control the levels of photosynthesis conducted by zooxanthellae
Too much oxygen could be shared with competitive corals

Too much oxygen could attract predators such as Parrotfish
Too much oxygen could cause the host to explode, as it is a gas formed underwater
