Answer:
Respiratory and circulatory
Explanation:
The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide. Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs.
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
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution.
