Ans.
Lipids are a class of biomolecules, made up of fatty acids and fatty acid derivatives. Lipids are non-polar, water insoluble organic compounds, which include fats (triglycerides), steroids, phospholipids, and natural oils. Lipids play role in different functions, such as in membrane synthesis (phospholipids), energy storage (fats), and signalling (steroids).
Thus, the correct answer is option) 'lipids.'

Hello!
Answer:
Yes, the burning of fossil fuels releases more carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are primarily composed of carbon and hydrogen. When they undergo combustion (are burned), oxygen present in the air combines with the carbon to form CO₂ and it forms H₂O with the water.
Every time fossil fuels are burned, they release large amounts of carbon dioxide (which is a greenhouse gas). Greenhouse gases trap heat in our atmosphere, which contributes to global climate change.
This is why it is important to use alternatives to fossil fuels whenever possible, such as solar or hydroelectric energy.
