This is True . the reabsorption through the proximal tubule is obligatory 80% whereas water reabsorption through distal tubule is facultative but mostly through collector tubules 15 % ( under the action of aldosteron and antidiuretic hormone).
Answer:
3215 F would be the platinum melting point.
it boiling point is 6917 F.
Explanation:
There is not much to explain other then heat melts metals when high enough, I know this because I own a forge and platinum is one thing I use for melting.
I think the answer is B. Immigration must outpace emigration. Hope this helps!
<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.
