What type of questions cannot be solved by scientific method?
a. questions about ethics
b. questions about extinction species
c. questions about the deep ocean
d. questions about the past

The correct answer is option A

Scientific method is used to answer the question that is based on science. These questions can be answered by the help of various set of protocols which has to be followed one after another.  

The protocols has to be followed in a proper manner such as aim, hypothesis, procedure, result and conclusion.

The questions related to ethics does not requires proper experiment. These questions can be answered based on person's opinion.

C

Explanation:

As i don't know why the other person put their answer as A you can but they might be racists but anyways the deep ocean we don't have advance enough tech to deal with the pressure per square inch and people or machines would be destroyed or kills before even reaching the bottom.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
