In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
Answer:
True
Explanation:
Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular substrate, for enzyme-substrate complex and later enzyme product complex to formed.
They act by lowering the activation energy in the organic chemical reaction therefore increase the rate at which chemical reactions progress.
Hence when the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.
Answer: Typed 2 diabetes; because plasma glucose molecules are retained in the blood and not able to enter the cells.
Explanation:
He suffered from type 2 diabetes because, the ketoacidosis was due to breakdown of fats in the liver due to low glucose in the cells, while the hypoglycemia was due to retention of plasma glucose in the blood instead of entering the cells.
