Scientist looked for the flowering hormone, which they named florigen for many years and finally have found it. What is florigen, i.e., what type of molecule? In what cells does it move throughout the plant? Does it act alone? (You do not need to know the detail but just the general concept of what happens in response to the correct environmental signal.)

When the protein comes out of the ribosome it may not be finished. What else may be needed to be done to the protein and how is it done? (Hint, chaperones, sugars and more.)

subsidiary cells- would this be cells that surround the guard cells and aid in their function.
Three different types of cell arrangements are the stomata? would this be correct
paracytic
Diacytic- orientation is at a right angle to the orientation of guard cells
Anisocytic- not equal around guard cells
Amphistomatic- stomata are on both sides of leaf, top and bottom
Hypostomatic- stomata are on the underside of leaf
These were the questions - the above are what i think the answers would be.
What is the name for the cells that surround the guard cells and aid in their function?
Describe in words or labeled pictures the three different types of cell arrangements around the stomata?

In the original eye deprivation experiments Hubel and Wiesel closed one eye of a few days old kitten. A couple of month later they measured neuronal activity in the contralateral V1. What did they find?
Group of answer choices
They found mostly monocular cells.
They found mostly ocular dominance category 2 through 6 type cells.
They found mostly binocular cells.
They found that the receptive field of V1 neurons became large and nonspecific.
They found that V1 neurons no longer responded to visual stimulus.

Does the somatosensory cortex have a columnar organization similar to the visual cortex?
a. Yes, alternating columns contain neurons responding to pleasant and aversive stimuli
b. No, columnar organization doesn’t make sense in the somatosensory system because the receptor types are too diverse to dedicate a full column to each sensory attribute.
c. No, the body is already represented several times in the somatosensory cortex, with different modalities assigned to different brain regions
d. Yes, alternating columns contain neurons responding to inputs arriving on the surface of the body and internal receptors
e. Yes, alternating columns contain neurons linked to slowly and rapidly adapting receptors.

Which of these attributes are similar between the visual and somatosensory systems?
a. All axons that carry information from the periphery are myelinated
b. All of these answers are correct
c. Topographical organization
d. Peripheral information reaches the cortex via the LGN
e. Peripheral receptors depolarize in response to environmental stimuli.
