After watching the video on flooding, what would be a major change that can
Delicious77 [7]

Answer:

Both

Explanation:

Depends on what happened in that video. I would rewatch it and write about what the video said about flooding and relate it to the river. Could be an ice jam or something else slowing the flow of water suddenly opened up. A breaking dam? Flash floods from an abundance of rain. As the amount of water in the river increases, so does the flow rate. If the amount of water suddenly increases more than the river was used to/it could hold, it will flood.

Rewatch the video and see if this relates at all :)

You conduct a mark-recapture survey of eastern fence lizards (Sceloporus undulates) in a 2-hectare plot in eastern Arizona. You
Ksenya-84 [330]

Answer:

Option C

Explanation:

Given -

Total number of initially marked lizards (M) = 250

Total number of recaptured lizards (C) = 75

Total number of recaptured marked lizards (R) = 24

As we know that -

\frac{M}{N} = \frac{R}{C}

We have to find "N" . "N" is the total population size of lizards in a 2-hectare plot in eastern Arizona.

Thus, on rearranging the above equation, we get -

N = \frac{M * C}{R}

Substituting the given values in above equation, we get -

N = \frac{250 * 75}{24} \\N = 781.25\\N = 781.3

Hence, option C is correct
