Explanation:
The correct answer is The cell is prokaryotic because it does not have any membrane-bound organelles.
Explanation:
Prokaryotic cells are different from eukaryotic cells because prokaryotic cells do not have organelles surrounded by a membrane, while eukaryotic cells do. These organelles include a nucleus, ribosome, among others. On the opposite, the DNA material is located inside the cell forming an undefined structure and the cell is protected by the cell wall and the cell membrane. In this context, the cell of the image is prokaryotic because there are no defined organelles inside it.

Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
- Species richness: Refers to the number of species are inhabiting a defined area.
- Species abundance: Describe the distribution of the species abundance.
Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
