Mitochondria because is the power house for cell,site for respiration or energy release.
Answer:
Explanation:
Hello,
In this case, we notice that the energy gained by the first sample of water is lost by the second sample of water as they are heated and cooled respectively, therefore, in terms of heats:
Which in terms of masses, heat capacities and temperatures is:
In such a way, as the heat capacity is the same and the initial temperature of the cold water is required, we solve for it via:
With the given data we obtain:
Which means the second sample was hot.
Regards.
The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The balanced equation can be written as follow:
Sodium bicarbonate => NaHCO₃
Hydrochloric acid => HCl
Carbon dioxide => CO₂
Water => H₂O
Sodium chloride => NaCl
Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.

Answer:
1,2 and 4 are correct
Explanation:
Enzymes that show cooperativity are defined as Allosteric enzymes. This cooperativity is of several types.
1) homotropic/homoallestery - positive cooperation
2) heterotropic/heteroallestery - negative cooperation
Activity of allosteric enzymes is regulated by other molecules (effector molecules)
Hence, statement 1 and 2 are correct.
Binding curve of allosteric enzymes:
For cooperative binding, binding curve is Sigmoidal curve
For non cooperative binding, binding curve is Hyperboilc curve.
Hence, statement 3 is wrong.
Allosteric enzymes have multiple active sites.
Allosteric enzymes are often multi sub unit proteins.
Hence, statement 4 is correct.
