Carbon cycle : - CO2 is given out when organism breathe - Plants gather this CO2 to produce oxygen - Oxygen that is produced by the plants is used for other organism's breathing which will given out another CO2 and repeat the cycle
Water Cycle : - Water from the sea and lake is evaporated and Turned into Clouds - When atmosphere cool it down, these clouds will condense and turn into rain - Eventually this rain will flow back to the lake or sea and it will repeat the cycle
<span>carbon cycle-> carbon dioxide is given out by cellular respiration and animal breathing :D--> this carbon dioxide is taken by plants and produced into oxygen :D--> eventually both the animal and the plant dies and they turn back into carbon :D---> over millions of years this carbon turns into fossil fuels and we extract it and use it for our energy and powerplants :D---> these powerplants release carbon dioxide into air and taken up by plants and yeaa..
water cycle--> water evaporates from the oceans and lakes--> water turns into clouds as it goes higher up the atmosphere cooling the water molecules making them condense and goes down as rain---> some rain percolates(goes through) the soil and stays there some percolate back into the lakes and oceans cycle starts over!!!! on a side note:the ones in the soil are taken up by plants and are put n the air through their tree breathing or transpiration(where water molecules are put in the air by plants)</span>
Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
<em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.

ever your small boat capsizes in the swift water, all you need to do is to float
on the upstream side of the craft and never try to walk in swift water nor
stand, and this will assure your safety. Also make your feet arms widely opened
or extended with your feet pointed to the downstream.</span>
