2. Nerves helps to send impulses or information from one place to another and it also carries sensory and motor fibres and most however are mixed nerves carrying both sensory and motor fibres.

3.The brain has many functions and the brain has different regions that deals with different functions in the body.

6.Reflex actions are automatic responses to stimuli.They do not involve the conscious (voluntary) or higher centres of the brain and so are also known as involuntary actions.

I think some of the answers are correct...Thank you for the questions

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

i think its 100.

hope this !
