Tell what is happening at each number.

1. Non-ligated insects show normal time of early trypsin mRNA. 2. Ligated animals don't produce the mRNA. 3. Ligated insects treated with JH nearly restores mRNA levels. 4. Non-ligated insects with JH treatment = faster appearance of mRNA.

In Belgica the midgut epithelial cells of the stomodeal valve

Explain in your own words what is shown in this figure. (Why is the
thingy on the left big and plump, and the thingy on the left all shriveled up) |
Cross section of upper parts of MTs in Rhodnius. Left was bathed in solution containing diuretic (tubule secreted water at high rate). Only occurs when exposed to diuretic hormone.

At certain temperatures the intervals between bursts were long. At the other end of the
temperature scale the burst of CO2 burst became increasingly cyclic, and CO2-release did no longer go back to a baseline. Below are shown the typical CO2-release patterns of resting honeybees measured at the two “extreme” ambient temperatures. Which graph do you think goes with Ta = 38.2 °C and which goes with Ta = 13.6 °C? Explain your answer |
Left graph, at higher temps metabolism rate is higher = more CO2 but also time spiracles are open needs to be minimized

describe the experimental set up that Krogh and Weis-Fogh used - at a minimum discuss A-F.
