A density independent factor refer to a weather or climate condition, which exert its influence on a population size without regard for the size of the population and its density. Limiting factor refers to any factor that put a limitation on the growth, abundance or distribution of a population. In the question given above, the Hurricane Katrina is a density independent factor because the hazardous event affected all the people that are resident in the affected areas.

EleoNora [17]

Answer:

1. Contains DNA and directs synthesis of RNA B. Nucleus 

2. Photosynthesis - make energy H. Chloroplast

3. Protein synthesis and folding D. Rough ER 

4. ATP production, cellular respiration A. Mitochondria 

5. Transport molecules around cell C. Vesicle 

6. Functions in storage and digestion F. Vacuole

7. Lipid and carbohydrate synthesis  E. Smooth ER 

8. Modifies, sorts, tags, packages, distributes proteins G. Golgi Apparatus

Explanation:

The cell is the functional unit of all living organism, it´s enclosed by a MEMBRANE in animals, or by a CELL WALL in plants and it´s formed by several organelles that are dispersed in the intracellular fluid or CYTOPLASM, positioned along the CYTOSKELETON, which gives structural integrity to the cell. Vacuoles, Chloroplast and Cell wall are found in plant cells. Each organelle has a distinct function within the cell:

Nucleus - Contains DNA and directs the synthesis of RNA.

Chloroplast - Photosynthesis - make energy.

Rough ER - Protein synthesis and folding.

Mitochondria - ATP production, cellular respiration.

Vesicle - Transport molecules around cell.

Vacuole - Functions in storage and digestion.

Smooth ER - Lipid and carbohydrate synthesis.

Golgi Apparatus - Modifies, sorts, tags, packages, distributes proteins.
