In the technique called optogenetics, light-gated na channels are introduced into the brains of living animals. activation of these channels by light can depolarize the membranes of neurons that contain them, selectively activating these target cells. since its inception, optogenetics has been expanded to include other types of light-gated channels, such as a channel that is selective for cl– instead of na . if this light-gated cl– channel were introduced into neurons in a region of the brain that stimulates feeding, what might you expect to see?

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
