The speed of a sound wave increase as it moves into deep water because sound waves travel faster as salinity decreases, and salinity decreases with depth.
Explanation:
Salinity, Temperature and pressure affect the speed of sound travels in ocean. At a depth of 1000 m in mid latitudes the sound is minimum. Sun makes ocean warm and the temperature become increase in their surface so sound speed becomes fast.
The wave amplitude is related to its carried energy. The wave who amplitude is high carries huge amount of energy and same low amount of amplitude wave carries low amount of energy.
Answer:
The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.
Explanation:
Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.
One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.

</em>
<em> d. Understanding the </em><u><em>causes of wheather change</em></u><em> does not correspond to knowledge in biology</em>
Answer:
C
Explanation:
You can not control your DNA.
Answer:
Scientists continue to add new kingdom to the system of classification because with the passage of time new organisms are discovered which have unique properties. These organisms donot fit to place in kingdom of classification. For example, protists are the organisms having both plants and animals characteristics so it cannot be placed into plants or animals kingdom so scientists make a new kingdom named protista.
