What 3 parts are in a nucleotide?
What 3 parts are in a nucleotide? Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine. Which of the […]

What would happen if there was no hydrosphere on earth?
What would happen if there was no hydrosphere on earth? We know weather happens in the atmosphere, but without the hydrosphere, there would be no water to evaporate and so no cloud or rain could form. Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of […]
How do the kidneys respond to acidosis?
How do the kidneys respond to acidosis? The kidneys respond to acid-base disturbances by modulating both renal acid excretion and renal bicarbonate excretion. These processes are coordinated to return the extracellular fluid pH, and thus blood pH, to normal following a derangement. What can the kidney do to compensate for acidosis? Renal compensation of respiratory […]
