Answer:
i-propyl cyanide
Explanation:
But i-propyl cyanide is the largest and most complex organic molecule found to date - and the only one to share the branched atomic backbone of amino acids. "The idea is to know whether the elements that are necessary for life to occur… can be found in other places in our galaxy."
Plantlike and methanogen organisms share som similar characteristics, for instance, can both produce their own and can process their made food into energy for different cellular processes such as cell division, repair and maintenance.
Despite this similarity though, the difference lies with the source of energy that get to produce the food. Plantlike organisms use sunlight and UV rays to photosynthesize. Whereas, methanogens use methane where sunlight is not present.
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
