exposure to drugs causes mutations which produce drug-resistant populations of microbes.

<h3>What is the effect of using same type of drug?</h3>

Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.

So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.

What is the life cycle of a butterfly?
Naddika [18.5K]
Butterflies undergo complete metamorphosis, and their life cycle contains 4 stages.

First, they are born as an egg. 

Then, they are hatched as a larva. They now eat flowers and leaves and will molt constantly. 

Next, they become a chrysalis, or a pupa. This is a resting stage.

Then is the long awaited adult stage, where butterflies take the form of the beloved, beautiful, winged insects we've come to admire. They no long grow and will now reproduce and repeat the cycle.

Hope this helps! Have a great day :)

You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200
Vsevolod [243]

Answer:

Option A 400 individuals

Explanation:

Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.

N = (MxC) / R

Where N = estimated Number of individuals in the population

M = number of individuals captured and Marked = 200

C = total number Captured the second time (with and without a mark) = 200 and

R= number of individuals Recaptured (those with a mark) = 100

Thus, we have

N = (MxC) / R

= (200 x 200) / 100

= (40,000) / 100

= 400 individuals.
