This would mean that it went 5 km for 10 seconds
5 x 10= 50km during that period of time
Answer:
The correct answer is - NO.
Explanation:
To be specific to the question, the answer would be no as analogous structures do not show that two distinct come from a common ancestor. However, it shows the evolutionary relationship by stating that the species have different evolutionary origins and developmental patterns as they developed the organs with similar function and appearance but anatomically and embryological development is different.
The answer to the question "Do wings show that a fly is related to a bird?", is no it does not show the relation between fly and bird.
<span>The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.</span>
Answer: C. The sign of the enthalpy of the reaction reverses.
Explanation: Enthalpy of a reaction is the net heat absorbed or released during a chemical reaction.It is represented by
. It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.
When a chemical reaction is reversed the heat of the reaction changes its sign.

The decomposition of calcium carbonate is an endothermic reaction as heat is required to break the bonds and thus energy is absorbed.

When the reaction is reversed, the reaction becomes exothermic as now bonds are getting formed and energy is released.
