Answer 2

Answer:

Renewable sources of energy are the types of resources that can be replaced after being used.

The hunger pangs or 'feeble yet sensational rhythmic contractions of the stomach and abdominal area' can continue up to 30-45 minutes. This occurs due to an increase in ghrelin hormone levels which motivate us to consume food to satisfy our hunger.

Explanation:

Classification of types of energy:

Energy is broadly classified into two main types:

• Renewable Energy (like solar energy, hydroelectricity, wind energy, geothermal energy, etc.)
• Non-renewable Energy (like energy obtained by burning of coal and petroleum, nuclear energy, fossil fuels, etc.)

What is Renewable Energy?

These energy sources are not depleted when used and can be repeatedly 'trapped' to produce useable energy.

Example- Electric energy is generated by harnessing sunlight and by using the power of flowing water (hydroelectricity). Both sunlight and water can be used repeatedly to produce this electricity without the worry of these sources getting depleted.

What are hunger pangs and their cause?

Hunger pains are:

• Light, moderate rhythmic contractions of the stomach and surrounding abdominal area.
• Hunger pains are caused due to increased amounts of the ghrelin hormone that is released by the brain.
• Ghrelin hormone stimulates the parietal cells in the stomach to release hydrochloric acid (HCl). Since the stomach is empty, the acid accumulates and reacts with the mucosal layers, which causes a slightly painful sensation.
• This painful sensation continues up to 30-45 minutes.
• The hunger pangs are a signal that the stomach is empty and apparently, the body needs food.
• Apart from the aforementioned conditions, psychological and visual/olfactory sensations may also trigger hunger pangs. E.g., a Feeling of hunger pangs when a delicious dish is kept right in front of you and you have not eaten anything for a quite lot of time!
