<u>Answer</u>:
<em>Dog drinking water after it feels thirsty is an example of an organism responding to its internal environment to maintain homeostasis.
</em>
<u>Explanation</u>:
The regulation of temperature of the body of an organism is called homeostasis. <em>Warm blooded organisms depend on their internal environment to maintain homeostasis while cold blooded organisms</em> completely depend on their external environment to maintain homeostasis.
The <em>body temperatures of warm blooded organisms maintain its constancy despite changing temperature of the external environment</em>. But the case of cold blooded organisms is different.
Their body temperature completely depends on the external environment and thus they have<em> several behavioral and physiological adaptations to maintain their body temperatures </em>at the comfortable level.
<em>In this example dog is a warm blooded animal and it drinks water to maintain homeostasis since water helps in thermal regulation of its body.

<span>Its weight, hope this helps :D</span>
Explanation:
<em><u>GIVEN </u></em><em><u>:</u></em>
Work done(W) = 40 J
Time(t) = 4 s
Power (P) = ?
<em><u>We </u></em><em><u>know </u></em><em><u>that:</u></em>
W = P×t
Therefore,
P= W/t
=40/4
= 10 W
<em><u>Hope </u></em><em><u>it </u></em><em><u>helps</u></em>
Average velocity = distance divided by time
Distance = 180
Time = 3 hours
180 / 3 = 60 m/s
