3ways the field of medicine relies on photosynthesis

1. because almost all medical remedies rely on plants 
2. it  makes plants grow and we are able to manipulate the light to effect the photosynthesis that it under goes to make new medicine
3. with different types of photosynthesis the pigments change and allows others to be able to take that medicine because that link is not longer there to be damaging to the body

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

It should be cryosphere and hydrosphere
