1) Common name and scientific name?
2) In response to low salinities, what will happen to this species?
3) Briefly explain the life cycle of this species.
4) This species consumes food through ____________
I cheated on #2
1) White Spotted Jellyfish [i]Phyllorhiza punctata[/i] 2) Low salinities will harm this species by causing them to loose their zoozanthellae. 3) The life cycle of this species involves two distinct phases, the medusa (adult, 2 year) and the polyp (juvenile, 5 year) stage. After fertilization of eggs occurs and larvae are formed, they leave their mother and settle to the ocean floor. Once on the bottom, a polyp form occurs and it reproduces asexually by dividing itself into other polyps. (That may not be specific enough/entirely accurate). 4) Mouthlets.
Ento is Lyfe. <3 Ento. <3 Bugs. <3 Insects.
I didn't choose the Bug Lyfe, the Bug Lyfe chose me.

Nice. What I originally put for #4 was filtration, although your answer works well too. Your turn!!

Oh, I interpreted it as you asking for the anatomical structure instead of the name of the process.

I'm confused, are glucosinolates toxic to animals?

According to this PDF: https://www.na.fs.fed.us/FHP/invasive_p ... itetop.pdf, "The species also contains compounds of glucosinolates, which can be toxic to some animals."

Oh, Ok, thanks

I'll start this up again sorry meteorology891..

1) Common name
2) What stage of growth is this in?
3) What species are similar?
3) How do you distinguish this stage from other species of the same stage?
4) How do you distinguish the adult stage from other species as adults?
5) Best method of control?

Answer
Canada Thistle Rosettes The spiny leaves Thin head, straight up (as opposed to "nodding" musk thistle), tubular florets I believe it depends on the stage, but two possibilities are weevils and herbicides

I believe it also depends on the environment and the number of native species nearby before you spray the herbicide. I might be wrong though...

1.Damage from what insect is shown here?
2. What order does this insect belong to (common or scientific) ?
3. Explain two effects this insect has had in the eastern united states.
4. What close relative of this insect has been responsible for the demise of Fraser fir (Abies fraseri) in its native range of Southern Appalachian spruce–fir forest?

Good
1 yep 2 hemiptera or true bugs 3 demise of Tsuga canadensis and caroliniana which is detrimental to the timber industry. elimination of hemlock also leads to brightening of ravines, and the resulting sunlight warms the water many species are dependent on, such as brook trout. 4 [url=https://en.wikipedia.org/wiki/Balsam_woolly_adelgid]Balsam Wooly Adelgid[/url]. Not necessarily a question that would ever come up, but if youre interested in invasive species good to know.
