<span>d. hypothalamus
The </span>hypothalamus<span> in the brain, is responsible for monitoring the body temperature. The hypothalamus causes the body to react differently when the body is too hot or if the temperature gets too cold.</span> <span>The normal body temperature is 37'. The hypothalamus triggers the receptors such as sweat glands and body hair muscles in the body.The sweat glands open up when the body is too hot and secrets sweat until the temperature is regulated again. Similarly in cold conditions the body hair muscles pull the hair upright because standing hair absorbs more heat until the falling body temperature returns to normal.</span>
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

The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.
<span>Some of the more common single-gene disorders include cystic fibrosis, hemochromatosis, Tay-Sachs, and sickle cell anemia.
Even though these diseases are primarily caused by a single gene,
several different mutations can result in the same disease but with
varying degrees of severity and phenotype.</span>
