Negative symbol which means that gain of electron.
I not sure about the answer sorry!! if you will get wrong in your book
Answer:
Sarcomeres
Explanation:
A muscle fiber is composed of many myofibrils, A sarcomere is the basic unit of a myofibril.
Sarcomeres are arranged in a stacked pattern throughout the muscle tissue, giving it a striped pattern. Sarcomeres are composed of thick and thin filaments. The thin and thick filaments interact initiate the movement of muscle.
Quantity of heat energy required for change of phase= (mass) x (heat of fusion or heat of vaporization), or in equation form Q=mL. Heat of fusion=80cal/g; heat of vaporization=540 cal/g
quanity of heat energy responsible for a temperature change= (mass) x (specific heat) x (change in temperature), or in equation form, Q=mcT
Here's another way to calculate it
Calculate the energy absorbed by 20 grams of 100 C water that is turned into 100 C steam
Q=(20g)(540 cal/g)=10,800 cal
I hope this helps you.
