Why is DNA called the blueprint of life?

Biology
1 answer:
jeyben [28]3 years ago
7 0
<span>Because DNA contains the genes that instruct the cells in how to build proteins. The genetic codes are the blueprints for each protein, and proteins control all biochemical reactions in the cell (as enzymes) and also form the structure of the cell, which becomes the structure of the entire organism. Without knowing how to build proteins, higher organisms would never have evolved.</span>

4. What is viscosity and how is it related to blood flow?
maria [59]

Increasing evidence supports the importance of hemodynamic forces that are directly related to the work of the heart as the primary triggering event of atherosclerosis and atherothrombosis. The factors that primarily determine the work of the heart include systolic blood pressure (BP), blood viscosity, and the volume of blood the myocardium has to pump.

The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase. Because of the dependence of systemic arterial BP on cardiac output and TPR, if blood viscosity and TPR rise, systolic BP must then increase for cardiac output to be maintained. Consequently, blood viscosity has been established as a major determinant of the work of the heart and tissue perfusion [1]. Since increased viscosity requires a higher BP to ensure the same circulating volume of blood, both the burden on the heart and the forces acting on the vessel wall are directly modulated by changes in blood viscosity.

Three important studies helped establish the relationship between blood pressure and blood viscosity. The earliest study observed 49 normal subjects and 49 patients with untreated essential hypertension, showing a direct correlation between BP and blood viscosity among both normotensive and hypertensive subjects (p<0.001). Systolic blood viscosity was 8 to 10% higher in hypertensive patients compared with normotensive controls, and diastolic blood viscosity was 16 to 28% higher in hypertensive patients. Subgroups each comprised of 25 subjects having matched hematocrits were also compared, and viscosity remained significantly higher in hypertensive subjects (p<0.05). [2]

sweet [91]
<h2>Stage of  Type 1 Diabetes</h2>

Explanation:

  • <em>"kids are not little grown-ups" </em>pediatric-beginning diabetes is unique in relation to grown-up diabetes due to its particular the study of disease transmission, pathophysiology, formative contemplations, and reaction to treatment.  
  • Imminent longitudinal investigations of people in danger of creating <em>type 1 diabetes</em> have shown that the sickness is a continuum that advances successively at variable yet unsurprising rates through particular stages before the beginning of symptoms.<em>type 1 diabetes creates in three phases  which are following.</em>
  1. Stage 1 is characterized of β-cell as confirm by at least <em>with normoglycemia and two islet autoantibodies  and is presymptomatic.  </em>
  2. Stage 2 is the β-cell autoimmunity with the presymptomatic  and dysglycemia. Beginning of symptomatic illness coming about <em>because of insulin lack in youngsters with type 1 diabetes.  </em>
  3. Stage 3 Reception of this arranging characterization gives an institutionalized scientific categorization to type 1 diabetes and may help <em>the improvement of treatments and the plan of clinical preliminaries to forestall symptomatic sickness.</em>
