Answer:
Option C
Explanation:
Given -
Total number of initially marked lizards (M) 
Total number of recaptured lizards (C) 
Total number of recaptured marked lizards (R) 
As we know that -

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 -

Substituting the given values in above equation, we get -

Hence, option C is correct
Answer:
B. There will be two cells each with 36 chromosomes.
Explanation:
The products of mitosis are called diploid cells, and they each have the complete set of chromosomes. These cells are usually important for activities such as growth, repair etc. They make up our normal body (somatic) cells. Therefore, the answer is 36, only 36 matches the description of genetically identical cells
The correct answer is D. Both absorb carbon dioxide from the atmosphere.
The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.
