The correct answer is D. Digestion.
Digestion is termed as the breakdown of food which has large insoluble molecules to small soluble molecules which makes them to be absorbed in the blood plasma.
Based on the way which food is being broken, it will depend on the form of catabolism which is used in the digestion. For example, catabolism is divided into chemical and mechanical digestion where mechanical digestion breaks down large to small pieces of food.
Those pieces of food are accessed by digestive system. In chemical digestion it is the enzymes which broke down molecules of food.
Answer: 2.3 g cm^3
Explanation: In this case the rise in level of water is same as the volume occupied by the stone.
a) Volume occupied by the stone = 70 cm^3 – 40 cm^3= 30 cm^3
b) Density = mass/volume
= 69g/30 cm^3 = 2.3 g cm^3
They both are encased organelle compartments inside a cell but A vacuole is the vesicle found within a cytoplasm of a cell. The vacuole contains some fluid. A lysosome, on the other hand, is an organelle found within the cytoplasm of eukaryotic cells.
All the members of a specific species that live in an area are a population.
Answer: B
Explanation:
Ammonia is so toxic that it can be transported and excreted only in large volumes of very dilute solution. As a result most terrestrial animals simply don't have access to sufficient water to routine excrete ammonia.
The main advantage of urea is its very low toxicity. Animals can transport urea in the circulatory system and store it safely in high concentrations. Also much less water is loss when a given quantity of nitrogen is excreted in a concentrated solution of urea than would be in a dilute solution of ammonia.
