Because warm air rises up so it's warmer on the top floor.
I think the correct answer would be the second option. The group of archaebacteria would be found on the lowest branch of a phylogenetic tree of all life. Phylogenic trees are illustrations of a hypothetical evolution of the organisms and its relationship with the other organisms. From the listed options, the archaebacteria is most likely to be the most basic and simplest life form. It should be placed before the other options so at the lowest branch. This illustration is being used by scientists to describe how evolution and the connection of the organisms came about. It sometimes called as the tree of life.
Answer:
the cells of all organisms in the domain eukarya contain a nucleus
<span>Chroloplasts Acts as a main role in photosynthesis.Chloroplasts likely orginated from engulfed "prokaryotes" that once lived as independent organisms. They are also considered to be originated from "cyanobacteria" through endosymbiosis—when a eukaryotic cell engulfed a photosynthesizing cyanobacterium that became a permanent resident in the cell.</span>

- Dosage, in particular the link dose-time.
- Exposure route.
- Species.
- Stage in life, such as child, young adult, or an older adult.
- Gender.
- Fitness to drink.
- Metabolism.
- Allocation inside the organ.
- Excretion
- Human safety, including organ function and childbirth, requiring physical effects that can affect toxicity.
- Nutritional status
- Many chemicals are available.
- Circadian rhythms (the time of day caused by a medication or other substance)
