Which of these statements is not true about insects? a, those that undergo complete metamorphosis have larval forms very different from the adult, with different food sources.
00:11
B, all of these are true.
00:13
C, other sites are cells in the email length of bicarious oxygen similar to mammalian red blood cells.
00:20
B, the first ancestral flying insects most likely had a pair of full wings, off both t3 and t2 sub -segments.
00:28
Or e, all insects have six legs in their adult forms.
00:33
Okay, so we'll start with d &e.
00:35
These are both through statements.
00:37
And for this, we can look at insects.
00:39
So all insects do have, all adult insects have six legs.
00:46
So that's part of their developmental pattern, the map of their body.
00:51
And from d, if we look at most insects, most insects do have these wings.
00:56
So it's an ancestral trait.
00:58
For insects.
01:00
So there aren't some insects that have lost some of these wings, but you can still see the holtirs, you can see that there are vestigial traits there...
