Answers
Answer:
Roughage also adds bulk to our diet and makes us feel full, thus helping in the weight management. Lack of roughage in our diet will, thus, result in constipation and increased blood sugar level, cholesterol levels and may also cause weight gain.
Here are just a few important ways water works in your body:
Protects body organs and tissues. Carries nutrients and oxygen to cells. Lubricates joints. Lessens burden the on kidneys and liver by flushing out waste products.
The major components of feedstuffs are moiasture, lipids, protein, fibre, carbohydrate, minerals and vitamins.
Many plants contain their own indicators – turmeric, red cabbage juice and beetroot juice are three good examples. Other examples are tea and red grape juice. Hydrangea flowers are different colours depending on whether the soil is acid or alkali. In acid soil they are blue and in alkaline soil they are red!
Answer: The nature of urea is acidic. we can verify it by using litmus paper. The blue litmus turns to red, concluding that its an acid.
Uses of Acids
It can also be used in the preservation of food. Sulfuric acid is widely used in batteries. The batteries used to start the engines of automobiles commonly contain this acid. The industrial production of explosives, dyes, paints, and fertilizers involves the use of sulfuric acid and nitric acid.
Malic acid
Malic acid is the predominant acid in many fruits, especially in apple (Wu et al. 2007; Zhang et al. 2010). In apple approximately 80 to 90 % of organic acids is malic acid
Eating junk food on a regular basis can lead to an increased risk of obesity and chronic diseases like cardiovascular disease, type 2 diabetes, non-alcoholic fatty liver disease and some cancers. We know Australian's eat too much junk food. 35% of adults' daily energy intake (kilojoules) comes from junk food.
