<u>Answer:</u>
<em>Land and sea breeze are produced because the land changes temperature rapidly than the ocean.
</em>
<u>Explanation:</u>
<em>The rates of heating up of land and sea are different. Land gets heated up faster than water. Temperature is crucial in determining the density of air.
</em>
When land gets heated up the air near the land turns hot and this temperature is greater than the temperature of the air near the water surface. <em>Hotter air has less density than the air which is relatively less warm. Density difference creates pressure difference.
</em>
Denser air has higher pressure than less dense air making air move from area of high pressure to area of low pressure. During the day<em> the land is heated up more and thus air move from sea to land and it is called sea breeze. </em>Just like it absorbs heat land releases heat at a faster rate.  
<em>Thus at night land the sea will be warmer than the sea and thus air will move from the land to the sea and it is called land breeze.

Peppered moth stimulation is an experimental setup that show the behavior of moth in relation to their environment. The objective of the setup is to stimulate changes in moth population as a result of pollution and predation. 
Peppered moth stimulation relates to the survival of the fittest because the moth with the most adaptive ability will be able to survive despite the negative forces in the environment. The bright colored moth was able to survive the pollution in the environment and retains its colour while the black coloured moth change its colour to black due to the pollution int the environment.
