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

How do I Construct a table to compare the products and reactants in photosynthesis and cellular respiration
katen-ka-za [31]

Explanation:

Create the column headings "Reactants" and "Products". The two row headings should be "Photosynthesis" and "Cellular respiration".

Before filling in the table, make sure you know what the products and reactants from photosynthesis and cellular respiration are.

Remember reactants are the 'before' on the left, and products are the 'after' on the right.

<u>Photosynthesis</u>:

CO_{2} + H_{2}O+light =>O_{2}+C_{6}H_{12}O_{6}

<u>Cellular Respiration</u>:

O_{2}+C_{6}H_{12}O_{6}=>CO_{2} + H_{2}O+ATP

See attachment for how the table could look.
