Answer:
Catabolic processes break down material and transforms fuels into cellular energy, whereas anabolic processes require energy for biosynthesis.
Explanation:
Metabolism is a constructive and destructive process which occurs in the body of living organisms. There are two types of metabolism i. e. catabolism and anabolism. Catabolism is a destructive process in which food molecules are broken down into simpler substances for the production of energy while anabolism used this energy for the formation of new cells and muscles etc.
Earths lithospere is solid and sits on top of the softer asthenosphere.
Answer:
Decrease in water/oxygen levels of the aquatic environment
Explanation:
<u>The environmental pressure that would cause primitive fish to adopt the genetic capacity to live on land would be a decrease in water levels of the aquatic environment.</u>
A constant decrease in water level that keeps exposing the fish to dry land will enable natural selection to start selecting for traits that will enable them to survive on land, especially, the development of lungs in the place of gills, the capacity to walk instead of swimming, and the capacity to avoid desiccation.
<em>A decrease in water level will mean a decrease in the amount of oxygen available for gill's respiration. Respiration is an important process for any organism to stay alive. </em>
<em>A decrease in water level also means an exposure to sun. The heat from the sun could cause death by desiccation.</em>
<em>A decrease in water level means that movement (through swimming) will be limited. Movement is necessary for feeding and other biological activities.</em>
