A biology student caught and tagged 50 trout in a small lake. After two weeks, the student caught another 40 trout and found tha
Vlad1618 [11]

The best estimate of the population of trout in the lake is 500 individuals.

The low number of tagged trout recaptured may be because the tags slipped off.

This possibility can be reduced if the student used tags that does not slip off easily.

<h3>Mark and recapture method</h3>

The formula for calculating the estimated number of individuals in the population is given as:

  • N = (M*C) / R

where:

  • N = estimated Number of individuals in the population
  • M = number of individuals captured and Marked
  • C = total number Captured the second time (with and without a mark)
  • R= number of individuals Recaptured (those with a mark)

Calculating the estimate trout population:

N = (50*40)/4

N = 50

Therefore, the best estimate of the population of trout in the lake is 500 individuals.

The low number of tagged trout recaptured may be because the tags slipped off.

This possibility can be reduced if the student used tags that does not slip off easily.

Neural control of gfr is mediated by ________ that innervate ________ receptors on vascular smooth muscle causing ________
storchak [24]

Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.

<h3>How is GFR regulated?</h3>
  • The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
  • GFR is the sum total of filtration rates of all the working nephrons in the kidney.
  • Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
  • In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
  • Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
  • Alpha receptors are more abundant on afferent arterioles.
  • This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
  • This decreases blood flow to glomerulus, leading to decrease in GFR.
