24 , electrical signal always move way from the cell body of motor neurone across the axon . it moves away from spinal because it is sending electrical impulse to effector so of course it will be away from spinal cord .
electrical impulse travels from receptor to spinal cord (CNS ) to effector .... if u did understand plz tell me :)
hope u got it

:D

24 is A..

When we see an object close to us... The suspensory ligaments are slackened and the lens are fatter...

In case of the object far away... Lens would be Thinner due to suspensory ligaments tightened....

32. D Both 5 & 3 are secondary consumers.... So they have the same trophic level...
