Antenna Biology

Well for Biology class I need to know what kind of caterpillar this is from this description.

It is smooth, green, has bright red antennas and has a strong odor.

Anyone know or got any guesses?

A terrestrial ainmal species is discovered with the following larva; characristics exoskeleton tracheal system for gas exchange and modified segmentation a knowledgeable zoologist would predict that its adults probably also would have
a eight legs
b two pairs of antennae
c a sessile life style
d an open circulatory sysytem
e parapodia

I googled it and got Arthroda species (spiders and insects). Sounds like ants? Ants have 6 legs, spiders have 8 according to the internet. Most insects only have one set of antenna, not two. Arthropods are sessile, or at least spiders are, but I would say ants are not.

Arthropods also have an open circulatory system, so I would say d, if it is ants.

"Female silkworm moths (Bombyx mori) attract males by emmiting chemical signals that spread though the air. A male hundreds of meters away can detect these molecules and fly toward their source. The sensory organs responsible for this behavior are the comblike antennae. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. Based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. What predictions does your hypothesis make? Design an experment to test one of these predictions."

I understand the story and have a hypothesis, but i don't get what they are asking me with the "what predictions does your hypothesis make". That question makes no sense if u think about it. HELP!!! thanks =]

The hypothesis is your guess about what is going on in the system. The predictions would include what you think will happen in your experimental design if your hypothesis is correct. The predictions could differ, based on how you go about setting up the experiment. So your basically asked three questions here:

1) Your observation of the situation and why you think it occurs (hypothesis)

2) How you would test this (experimental design)

3) What will be the outcomes of the designed experiment if your hypothesis is true, and how will the outcomes differ if it is not true (predictions)

1. Which statement regarding events in the functioning of photosystem II is FALSE?

A. Light energy excites electrons in an antenna pigment in aphotosynthetic unit.
B. The excitation is passed along to a molecule of P680 chlorophyll in the photosynthetic unit
C. The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+
D. The electron vacancies in P680 are filled by electrons derived from water
E. The splitting of water yields molecular oxygen as a by-product

2. All of the following are directly associated with photosystem I EXCEPT

A. Harvesting of light energy by chlorophyll
B. Receiving electrons from plastocyanin
C. P700 reaction-centered chlorophyll
D. Extraction of hydrogen electrons from the splitting of water
E. Passing electrons to ferredoxin

1. (c)
--not protons, electrons.

2. (c)
--not p700, p680

14. Which is incorrect about photosynthesis? 
A. The light reactions take place in the cytoplasm and the dark reactions occur in the chloroplast.
B. The light-independent reactions don't require light but can occur in its presence.
C. The light-dependent reactions produce NADPH and ATP.
D. The light-dependent reactions release oxygen.
E. Photosystems act as antenna to capture photons.
23. Which of the following does not do photosynthesis? 
A. algae
B. leaves of plants
C. some bacteria
D. roots of plants
E. none of the choices is correct.
29. A photosystem transfers the excitation energy gathered by its pigment molecules to a specific chlorophyll at the reaction center. 
True    False
30. _____________, which is provided by the photosystem, provides a source of hydrogen and the energetic electrons needed to bind them to carbon atoms. 
33. The molecule that supplies energy in the body is ____________. 
34. Stoma open at night in plants that use _______ photosynthesis. 

i think 14 is A not sure though
23 should be C because some bacteria don't do photosynthesis and some do, but it could just be linguistics there. I don't think roots of plants would do photosynthesis since they aren't exposed to light
29. True
30. water
33. glucose
34. CAM
