One way to determine the density of animals in an area is to use the mark-recapture technique. A number of individuals from a po
NNADVOKAT [17]

Answer:

N = 187.55

Explanation:

Here you just need to replace the terms and clear the equation.

You already know that,

  • First capture: 25 prairie dogs.
  • First marked animals: 25 (the whole first capture)

You let these animals leave and then you made another capture.

  • Second capture: 135 prairie dogs
  • Already Marked animals: 18 (these 18 dogs were caught in the first capture and marked before releasing them)  

To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.  

Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch

  • Number of individual marked in first catch = 25 dogs
  • Total population size, N = this is what we want to know
  • Number of individual marked in 2nd catch = 18 dogs
  • Total number of 2nd catch = 135 dogs

So now, we need to replace terms

25 / N = 18 / 135

25 / N = 0.1333

N = 25 / 0.1333

N = 187.55

Debora [2.8K]

Explanation:

The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.

Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.

  • Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
  • Tool man also grazed the surface of the earth just a few thousands to a million years.
  • We are able to find their fossils in rocks because they have lived in some certain geologic periods.
  • Here we are using the fossils to date the rock and this is called relative dating

What is the appropriate dose of 1:10,000 (0.1 mg/ml) concentration of epinephrine for endotracheal administration to a baby weig
vlada-n [284]
I believe the appropriate dose will be 1.5 mL, 
Epinephrine is used for both allergic reaction and heart attacks, in an effort to increase blood flow through veins and to reduce swelling in airways. When epinephrine is recognized by receptors on smooth muscles, it causes airway-blocking muscle constriction to subside. Other drugs that may be administered by the endotracheal route include atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate.
