Prokaryotic cells have a nuclear while eukaryotic cells have a nucleus. Eukaryotes have membrane bound organelles. Eukaryotes have chromosomes while prokaryotes do not. Also prokaryotic cells have circular DNA while eukaryotic cells have linear DNA, or "double helix".
<u>Answer:</u>
Composting food scraps in the cafeteria to reduce landfill waste would have the greatest impact in reducing the school’s ecological footprint.
Option: (C)
<u>Explanation:</u>
- Reducing the ecological footprint means bringing about some changes in lifestyle and living to improve the biocapacity.
- Compositing food scraps in the cafeteria to reduce landfill waste is the best option that the environmental club can apply to reduce the school's ecological footprint.
- This step can help to increase productivity of soil as well as reduce waste in landfill site.
- The option of incineration of trash causes air pollution. Likewise, reducing recycling bins will not be helpful in decreasing the ecological footprint.
- Instead, it causes the unmanaged collection of trash in school environment.
There are a few differences between animal cells and plant cells.
Plant cells have cell walls, and animal cells do not.
Plant cells have a large central vacuole and animal cells do not.
But probably the most recognizable (and probably the one your question is asking about) is the chloroplast. The Chloroplast is the home of chlorophyl, a green pigment plants use to make energy.

The right option is D. vector-borne
Diseases carried from person to person through other hosts, such as animals or insects, are known as vector- borne diseases.
Vector-borne diseases are infectious diseases transmitted between humans or from animals to humans through the bite of infected hosts such as animals or insects. Most of these hosts are arthropod vectors which are bloodsucking insects such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Examples of vector-borne diseases include West Nile fever which is transmitted through the bite of an infected Culex mosquito, Leishmaniasis which is transmitted through the bite of an infected female sandfly and Tick-borne encephalitis (TBE) which is transmitted by ticks.
