Explanation / Answer

There r too much ques.according to guideline I should answer first four but for ur conveinieco I m answering all but explaining only first four

Ans 6..true

As the law of equilibrium say energy can not be produced or destroyed .it can be transferred from one form if energy.the energy produced from oxidation of glucose is balanced by motion and the heat produced

Ans 7..myosin

Myosin is not a part of thin filament.it is thick filament

Ans 8.. Hypothalamus

Hypothalamus has temperature control nucleus in it which by heat loss or by preventing heat loss regulate body temperature

Ans 9...true

In isometric contraction I band remains same but in isotonic it decreases

Ans 10.. actin

When after binding of tropnin with calcium the myosin binding site on actin gets exposed and the myosin bind with actin and crossbridge formation occur

Ans 12....many neurons fewer branches

Eye movement is contolled by 3,4 ,6 cranial nerve

Ans 13....B

Myosin head detached from actin

Ans 14..false

Ans 15. B

Ans 16..A

Ans 17..B

Ans 18...A

Ans 19..true

Ans 37...B

Ans 38..true

Ans 40...true

Ans 43..false

Ans 45...true

Ans 46...true

Ans 47..True

Ans 48...true

Resting membrane potential is negative. There are more positive ion outside and more negative ion inside
