Answer:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history
Explanation:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history describe Faunal succession because it is a principle that indicate that fossil plants and animals succeed each other in a sequential manner even if they occur in different places. Successive strata and faunas are linked together to form composite section in the Earth's history.

Answer: The correct answer is: the water can transfer heat to your arm more quickly than the air.
Explanation: The heat is transferred from the air or water to your arm through convection. The convective heat transfer coefficient of water is higher than the air's, so, even though the temperature of boiling water is lower, the heat will be transferred more efficiently to the other surface, in this case, the hand.
Answer:
21 kJ
Step-by-step explanation:
The formula for the heat q is
q = mCΔT
<em>Data:
</em>
m = 200 g; C = 4.184 J·°C⁻¹g⁻¹
T₁ = 50. °C; T₂ = 25 °C
<em>Calculations:
</em>
ΔT = T₂ - T₁
ΔT = 25 – 50.
ΔT = -25 °C
q = 200 × 4.184 × (-25)
q = -21 000 J Convert to kilojoules
q = -21 kJ
The negative sign shows that energy is released, so the water has released 21 kJ of energy.
