Thank youA) The lamb is stimulated by the licking to begin nursing from its mother B) the sooner a lamb begins nursing, the better its chances for survival. Which of the following identifies the causes of the behaviors described? A is the proximate cause and B is the ultimate cause A is the ultimate cause and B is the proximate cause Both are ultimate causes O Both are proximate causes
Explanation / Answer
Que 51. The lamb is stimulated by licking to begin nursing from its mother., B) the sooner a lamb begins nursing, the better its chances for survival both are ultimate causes of behaviour
The lamb is stimulated by the licking to begin nursing from its mother and the sooner a lamb begins nursing, the better its chances for survival. these are ultimate causes of behaviour
Que 52. ability to grow continuously is not benefit of the exoskeleton in insect
Insects exoskeleton limits the animal’s ability to grow continually, and may limit the individual’s ability to mature if molting does not occur at the proper time.
Que 53. rigor mortis happens when dead organism runs out of ATP when is ATP used during muscle contraction
return the myosin head to its unbound conformation.
ATP is spent to change the orientation of myosin head which helps in sliding actin filament during contraction.
ATP is used to actively pump calcium ions back into sarcoplasmic reticulum i.e. out of the cell cytoplasm (=sarcoplasm)
Que 54. unrelated individuals engage in apparently altruistic acts if the altruism is likely to be reciprocated
Que.55. ATP hydrolysis, the myosin head unbinds the cross bridge is the last step in the muscle stroke cycle
Myosin reactivates when the free myosin head splits ATP into ADP and a phosphate. The energy released is used to recock the myosin head and the process starts all over again.
