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

Choose the CORRECT statement about enzymes below.
Papessa [141]

Answer:

Enzymes function best at specific pH and temperatures.

Explanation:

An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
