Answer:

Calcium ions.

Explanation:

The generation of the action potential helps in the transfer of information to the different body parts. This potential occurs to the difference in membrane potential inside and outside of the cell.

The sarcoplasmic reticulum is the homologous to the endoplasmic reticulum of the cells. The sarcoplasmic reticulum contains calcium ions in it and releases the stored calcium ions on the generation of the action potential. This calcium ion is important for the action of the actin and myosin.

Thus, the correct answer is option (D).

Object A specific heat is 2.45 J/g C and object B specific heat is 0.82 J/g C. Which object will heat up more if they have the s
Artist 52 [7]

Answer: Object B will heat up more.

Explanation:

The formula for specific heat is as follows.

                  Q = m C \Delta T

Where,

                      Q = heat provided

                      m = mass

                      C = specific heat

            \Delta T = change in temperature

Now, both the objects have same mass and equal amount of heat is applied.

According to the formula, the equation will be as follows.

                      Q_{1} = Q_{2}

                  m C_{1}\Delta T = m C_{2}\Delta T_{2}

Cancel m from both sides, as mass is same. Therefore,

            C_{1} (T_{f} - T_{i})_A = C_{2}(T_{f} - T_{i})_B

Cancel out the initial temperature and put the values of specific heat, then the equation will be as follows.

             2.45 (T_{f})_A = 0.82(T_{f})_B

Therefore, from the above equation it can be concluded that the object with low specific heat will heat up more as its specific heat will be inversely proportional to its final temperature.

Hence, object B will heat up more.
