Answer:

Watson & Crick

Explanation:

They received the Nobel prize for science for their discovery in 1962. Their capacity to be able to represent DNA double helix in 3D was made possible by advancements in the model building- a science that allows three-dimensional structures to be modeled based upon known molecular distances and bond angles.

ateo goes to his doctor after experiencing discomfort for a few days. Following tests and an examination, the doctor tells Mateo
RUDIKE [14]
This is a case of acute or chronic (or acute on chronic) kidney disease. Mateo should take diuretics or drugs that induce tubular secretion and/or water excretion and therefore urination. If kidney disease worsens, the patient will undergo filtration of waste products from his blood or this is called hemodialysis. There is another way of filtering waste products using the fluid in the peritoneum called peritoneal dialysis. Other complications of chronic kidney disease is anemia as erythropoeitin (functions to signal the production of red blood cells) is produced in the kidneys.

What is so special about nitrogen in the atmosphere
HACTEHA [7]

Answer:

Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.

Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.

Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
