Blood clots will do this.  Cutting off blood flow while also increasing blood pressure.  Also, if the viscosity (thickness of the blood) is thick which will slow down the flow and cause the body to use more effort to pump blood.

The data obtained from the meselson–stahl experiment after one generation of replication eliminated the dispersive model of dna
Sedaia [141]
<h2>Given statement is false</h2>

Explanation:

According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA

Meselson and Stahl did an experiment on DNA replication using E.coli bacteria

  • E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNA
  • It was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogen
  • Bacteria were then switched to light nitrogen isotope and allowed to grow for several generations
  • They then measured the density of the DNA using density gradient centrifugation
  • This method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chloride
  • Each DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)
  • Each DNA strand act as a template for synthesis of new strand
  • Hence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment
