The answer is 23 chromosomes.
Exo means outside
So planets outside our solar system
The correct answer is D. Bacteria and archaea
Explanation:
In biology, cells can be mainly classified into prokaryotic and eukaryotic. The prokaryotic cells are cells with no nucleus or centrioles but they do have a cell wall, usually one chromosome and complex cilia and flagella. On the other hand, prokaryotic cells have a defined nucleus, multiple chromosomes, and centrioles and some have a cell wall. Due to the differences between these two type of cells they are part of different organisms, in the case of eukaryotic cells, these are part of the complex organism that includes animals, plants, and fungi while prokaryotic cells are those found in bacteria and archaea which are organisms with only one cell. Considering this, the ones that consist of prokaryotic cells are bacteria and archaea.
The carrying capacity for a species in an ecosystem is primarily determined by the resources in the ecosystem.
<u>Explanation:</u>
The availability of food, raw materials, water and other resources in that ecosystem are those factors that is used for the determination of the carrying capacity. The factors such as nature, the levels of wastage accumulation, removal of very important things from the system also determines the carrying capacity. a system's carrying capacity may involve matters such as available supplies of food, water, raw materials, and/or other similar resources.
The main components that determines the carrying capacity of an ecosystem are food and other resources, provided, the humans must not disturb the ecosystem for their self survival. The resources limitations and their availability determines this factor to a greater extent.
