Which enzyme is mixed with a DNA sample before gel electrophoresis
Svetach [21]

Answer:

Restriction enzyme

Explanation:

  • Gel electrophoresis is a process or a technique in which fragments of DNA  are separated in terms of their sizes.
  • <em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
  • When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.

why might changes to the gulf coast prairies and marshes ecoregion happen more quickly then to other ecoregion?
liq [111]
The reason for this is because it is closer to water, therefor they have more events that could happen. Also there is a lot of weathering, erosion, and deposition which makes the gulf coast prairies and marshes more susceptible to changes. 

I hope this helps!

The digestive and excretory systems
hammer [34]

THE EXCRETORY SYSTEM

Answer: The attachment shows the nephron which is the functional unit of the kidney.

It does the work of urine formation through 3 distinct processes.

-Ultra filtration( Small molecules are forced out of the selectively permeable membrane of the glomerulus into the Bowman's capsule under regulated pressure.these molecules are from the blood in the glomerulus brought in by the afferent arteriole.

- Selective reabsorption ( Useful molecule and iron such as glucose and sodium are reabsorbed back into the blood as the filtrate flows through the tubule(nephron)

-Tubular Secretion. ( Movement of molecules not filtered by the glomerulus during the initial stage of filtration back into the filtrate through the renal capillaries.

Stella's urine sample shows the presence of large protein (ULTRAFILTRATION)

John's blood test report indicates a high toxin level ( ULTRAFILTRATION AND TUBULAR SECRETION)

Miguel's blood test shows an increase in metabolic waste( ULTRAFILTRATION AND TUBULAR SECRETION)

Janice's urine report shows the presence of vital materials ( SELECTIVE REABSORPTION).
