<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.

Answer:
<em>S. aureus</em> is spherical and arranged in clusters
Explanation:
<em>Staphylococcus aureus </em>is a gram positive bacteria that forms a part of our body microbiota. It is usually found on skin and in upper respiratory tract. The genus name of this organism is <em>Staphylococcus </em>which tells a lot about its morphology. Cocci or coccus is the name given to bacteria who appear spherical. Staph points out to their arrangement which is in clusters. Had it been <em>Streptococcus</em>, it would mean that the bacteria were spherical and arranged in long chains. Similarly, <em>Diplococcus</em> would mean that the bacteria were spherical and arranged in groups of two. Hence from the name <em>Staphylococcus aureus </em> we can say that it is spherical and arranged in clusters.
The correct choice is A. Since in this food chain bluebirds are the predators of worms, if bluebirds became extinct the worm population will eventually grow since their predator is gone.
