Signaling within organisms can occur using action potentials (short-term signaling) and/or hormones (long-term
signaling). Identify situations where each type of signaling would be better. Describe why having a long-term signaling
system is beneficial to organisms (2-3 sentences).
Amoebae extend pseudopodium which is a temporary actin-based protrusion of their body membrane to probe and crawl. Elaborate the directed movement of Amoebae response to extracellular chemical stimulants. Cite a specific chemical stimulant to elucidate your idea.
As mentioned, large priapulids thrive in habitats intolerable to most other animals. What would be the implication of this on their feeding habi?

- What type of signal transduction is involved in signaling from hormones such as estrogen and testosterone? Explain the signal transduction pathway that occurs. 1. Is there a short term description for signal transduction, instead wrting multiple words to descripte the type of signal transduction? Can I just identify it as active signal transduction and inactive signal transduction. Based on my understanding, active singal transduction is for the fast react transdcution, while inactive signal transduction meanly refers the hormonal affacts on the system. 2.

You hypothesize that 2 intracellular signaling proteins, named GO and TIGERS, interact with each other when cells are treated with an extracellular source of CAMP. The two proteins were tagged with CFP or YFP (CFP = cyan fluorescent protein; YFP = yellow fluorescent protein). CFP is excited by 435 nm light and emits lights at 480 nm. YFP is excited by 480 nm light and emits light at 535 nm. 400 500 Wavelength of Emitted Light 400 500 Wavelength of Emitted Light 600 600 Fluorescence 400 400 500 Wavelength of Emitted Light 600 500 Wavelength of Emitted Light 600 Fluorescence Intensity 400 500 Wavelength of Emitted Light 600 Figure Legend.
