The method in which we used microorganism metabolism to remove pollutants such as oil spills in the water bodies is known as: 1. Biomagnification 2. Bioremediation✔️ 3. Biofortification 4. None of these

Which of the following group does NOT follow New lands Law of Octaves? 1. Li, Na 2. Be, Mg 3. C, Si 4. Mn, Hg🔗

Increasing the amount of a substance does not change its- 1. Volume 2. Weight 3. Mass 4. Density✔️

Density of an object depends on its mass and volume. Density can be found by using the equation: Density = Mass/Volume

Rennin is a proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins. • Pepsin is a digestive enzyme that converts proteins into proteases and peptones. • Trypsin is also a digestive enzyme that activates other enzymes in the pancreatic juice. • Trypsin is formed in the small intestine while Pepsin and Renin form in the Stomach. • Lipase is secreted by gastric glands and activated by bile juice in digestion.
