2. smooth ER h. site of lipid synthesis

3. mitochondrion a. main site of ATP synthesis

4. nucleus b. encloses the chromatin

5. Golgi apparatus e. forms basal bodies and helps direct mitotic spindle formation and j. packages proteins for transportation

6. lysosome c. sac of digestive enzymes

7. centriole k. internal cellular network of rod like structures  

9. inclusion d. examples include glycogen granules and ingested foreign materials

10. plasma membrane g. forms the external boundary of the cell

11. nucleolus i. packaging site for ribosomes

Explanation:

Ribosome is considered as a site of protein synthesis,  smooth endoplasmic reticulum is the site of lipid synthesis , mitochondria is the main site of ATP production, nucleus encloses the chromatin material inside it,  Golgi apparatus forms basal bodies and helps direct mitotic spindle formation and also packages proteins for transportation,  lysosome is a sac of digestive enzymes , centriole consists of internal cellular network of rod like structures  , inclusion has examples include glycogen granules and ingested foreign materials,  plasma membrane forms the external boundary of the cell  and nucleolus has the function of packaging site for ribosomes.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
