Which of these statements about osmoregulation is true? a, in freshwater invertebrates, salts move out of the body into the water because the animal's hypoosmotic to water.
00:12
B, a marine teleost has to fight gaining water because it is isoosmotic to the c.
00:17
C, land animals typically are osmocomformers.
00:21
D, vertebrates are typically osmoregulators.
00:24
Or e, terrestrial animals can regulate osmularity without expending energy.
00:29
So, e, is just false.
00:30
If you want to regulate osmolarity, energy will be involved.
00:34
In a terrestrial animal, this might look like having to find water, or having to find salt, or excruiting salt.
00:42
The energy is going to be involved.
00:45
Okay.
00:46
In freshwater invertebrates, salts move out of the body.
00:49
So this is not true.
00:51
It's not salts that move...
