Assumption of the mating , the GnRH surge (c)
Lordosis is the assumption of mating posture in response to the GnRH surge. The sexual behaviour and physiological readiness to mate are cordinated by the gonadotrophin releasing hormone.This reflexive posture is diplayed by the female mammals in response to facilitate the sexual behaviours of male.
Add Answer to:
Lordosis is in response to a. Activation of sensory neurons, the male b. Assumption of the...

You isolate two new loss-of-function mutations in C. elegans which affect the differentiation of sensory neurons. In one mutation, nos-1, the worms cannot sense where the food is in their environment. In the second, yum-1, they are hypersensitive to their food source. Which of the following regulatory pathways is/are consistent with the results so far? Note that a pointed arrow ( → ) indicate activation and the blunt arrow ( ---| ) indicates inhibition. Question options: a) nos-1 ---| yum-1...

Response Questions Part A To B The roundworm Caenorhabditis elegans is a widelystudied animal model, in part because ofits small number of neurons and easilymanipulated genome. Nociception is the neural perception of an actually or potentially harmful stimulus. In C. elegans, it evokes a self-preserving withdrawal behavior. However, repeated stimulation can result in reduced withdrawal response, or habituation. Researchers compared the withdrawal response to disturbing light stimuli in wild-type C. elegansand a mutant C. elegans line that exhibits a slower...
