It is unavoidable – It is impossible not to communicate‚ since we communicate unintentionally all the time‚ even without the use of words. Our body language‚ the way we dress‚ the importance we give to arriving on time‚ our behavior and the physical environment in which we work‚ all convey certain messages to others. It is a two-way exchange of information – Communication is sharing of information between two or more persons‚ with continuous feedback. It is a process – Each message is part

Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also

Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my

Denudation Processes While volcanic activities are a mountain’s building process‚ denudation processes are trying to level them down. Denudation includes processes which removes rock debris and carrying them to a new location. These processes happen through gravity‚ wind‚ ice and water. In the Tongariro Volcanic Centre‚ winds are an effective denudation agent because the mountain top gales are frequent and severe. Winds can transport and deposit debris. They carry with them fine silts and sand

mouth is a part of the body where people use mechanical digestion and use their teeth to break down their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch
