The Sun is the main cause for our weather, and different season (in different areas where you live it depends on how hot or cold it is also caused by the sun)
Most seasons, like in summer it's hot Also caused by the sun, in winter it snows because the sun is in a different location.
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
The answer is Glucagon Increases. This works like this after
a meal of a rich carbohydrate, over four to six hours the blood glucose level
rise, leading to an increase in glycogen. Produced by alpha cells of the
pancreas and released in response to low blood glucose and epinephrine.
Secretion inhibited by high blood glucose and insulin. Stimulates glycogen
breakdown and inhibits glycogen synthesis
