Answer:
1) intake of glucose molecules from the blood by specific transporters
2) high amount of glucose in the blood, sending signals toward the pancreas
3) binding of hormones with receptors on the liver
4) release of hormones from the receptors
5) synthesis of hormones by beta cells
Explanation:
During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells. The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
The correct answer is - C) carotenoids.
The majority of the trees from the mid-latitude forests tend to shade their leaves in the autumn. This process occurs because of the seasonal changes in the climate, where the trees tend to be almost not-active during the winter, so in order to preserve as much energy and nutrients as possible they get read off their leaves.
It is not a sudden process, but it takes some time, where the leaves from the initial green color start to change to yellowish, than towards orange, reddish, or brownish before they fall.
The reason why this coloration appears in the leaves when the tree starts to process of shading them off are carotenoids. The carotenoids found in the leaves, the lutein and the beta-caroten, thorugh the xantophills and the flavonoids give a yellowish color to the leaves, thus we get the beautiful autumn colors and landscapes.
The sun rays that hit the equator are hotter because the equator is pointed more to the sun
Rays that strike the poles arent that effective because of the earths tilt, and it's rotating and revolving constantly
