If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:
- <em>CENTRAL VACUOLE
</em>
- <em>plasma membrane
</em>
- <em>
cell wall
</em>
- <em>
chloroplast</em>
The correct answer as to which of the organelles the cell must have would be the plasma membrane.
- central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
- All cell types have plasma membrane.
Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.

Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
- <em>The other options are not correct because </em><u><em>none of them show environmental pressure that can lead to natural selection</em></u><em>.</em>
