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

In the case of G0, that is, the stationary phase, the mammalian cell can pass the restriction point with the supplementation of extracellular proliferation signal. While in the case of G1, which actually does not require any kind of external proliferation signal, as once the cell is in G1 phase, it is ready to go get the next phase. However, both the mammalian cells will cease or halt at G2 checkpoint.
