Answer:
16 KJ or 16,720 J energy has gained by the water.
Explanation:
<em>Given data:</em>
Mass of water = m = 100 g
Temperature difference = ΔT= (60 - 20)∘C
specific heat of water 1 calorie = c = 4.18 J
<em>To find:</em>
Heat absorbed by water = q=?
<em>Formula:</em>
q = m . c . ΔT
<em>Solution:</em>
q = (100 g) x (4.18J/g ∘C) x (60 - 20)∘C
= 16,720 J

Mitochondria is known as the power house of the cell and one of the important organelle responsible for the production of energy. Mitochondria contains its own DNA.
To understand the maternal ancestor history, the mitochondria DNA must be studied. The mitochondria is solely obtained from the mother as the egg contains large amount of cytoplasm that contains mitochondria. The mitochondria can never be inherited from paternal origin as the sperm contains few amount of cytoplasm and mitochondria.
Thus, the answer is mitochondrial DNA.
