1. lung.
2. cells.
3. do all jobs for survival.
4. bacteria.
5. producing offspring.
6. Taxonomy.
7. a cell dividing.
8. obtain energy, produce offspring, and maintain their structure.
9. soil.
10. food, water, air, and a place to live.
Explanation:
1. all of the other options are organisms, while a lung is an organ.
2. All living things are made of cells
3. All unicellular organisms must be able to perform all the functions necessary for life. Meaning do all the jobs needed for survival.
4. Bacteria is the organism listed that is able to cause an infection or contagious disease.
5. A fish laying hundreds of eggs is an example of producing offspring. While it could also be an example of maintaining structure, a fish cannot obtain energy by laying eggs. So, the best answer is producing offspring.
6. Taxonomy's definition is the branch of science concerned with classification, especially of organisms; systematics.
7. a cell dividing is maintaining structure. After growth, cell division by mitosis allows for continual construction and repair of the organism. The primary concern of cell division is the maintenance of the original cell's genome. So, this is the best option for the question.
8. The second option is wrong, because not every organism plays video games. The 4th option is wrong, because not every organism builds their own home. And finally, the first option is incorrect, because plants do not physically eat they obtain their energy through photosynthesis. So, the correct option is the 3rd one.
9. Soil is not needed for all living organisms, but the other options listed are necessary.
10. the second and third option are incorrect, because not every living thing needs a parent. The first option is incorrect, because not every living thing needs sunshine and it does not list the other necessary components. So, the correct answer is the last option. And a place to live can also mean an appropriate environment.
The ocean is actually an open system so matter and energy move freely throughout the land, the ocean, and the atomsphere, but if this were an isolated sytem this would be completely different. An isolated sytem does not allow any energy or matter to leave keeping what it has trapped inside its system and does not allow any energy or matter to enter. So if the ocean became an isolated sytem, to try and get energy from it, divers and workers would have to go in and extract the energy from the ocean similarily to what they do now, but it would be harder.
