Answer:
this is not science questions it is of maths
The correct option is D.
Both carbohydrates and fat produce energy within the cell, but the amount of energy produce by fat for each one gram of food is much more than that of carbohydrate. Fat in the food is absorbed into the body in form of triglycerides.
Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.
The genetic code is based upon reading 3 bases at a time
there are 4 nucleotides bases in DNA and 20 amino acids .
In order to incorporate all the amino acids we consider 3 bases in genetic code
4 x 4 x 4 = 64
if we would take 2 bases -
4x4 = 16 that would leave out 4 amino acids without a code .
The correct answer from the choices listed above is option A. Adaptations took advantage of the presence of free oxygen in the oceans and atmosphere by the <span>evolution of cellular respiration, which used oxygen to help harvest energy from organic molecules.</span>
