Butan-2-ol can be produced as a result of reducing butanone with NaBH4. The hydride ion in NaBH4 is used as a nucleophile which can attack the C on the (C=O )either above or below the plane, depending on ...

Photosynthesis occurs in the leaf (source), making sugars: fructose and glucose. These are converted to sucrose and are actively transported into the phloem (sieve tube element) by companion cells. The in...

Soil is extremely important to sustain human life, with 95% of food coming from soil. Soil degradation has occurred globally due to mass farming and the use of unsustainable techniques such as using heavy...

Electrical impulses are sent through a neuron’s axon which are translated into chemical signals at the terminal button. Here, vesicles containing neurotransmitters are released which fuse with the outer m...
