T-rex lived in the Late Cretaceous period during the Mesozoic era. Dunno if this was precisely what you were looking for, but I hope it's helpful!
The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain <u>Eukarya</u>.
- The only domain that includes multicellular, visible organisms including humans, animals, plants, and trees is eukaryote.
- Numerous microorganisms, including fungi, algae, and micro-animals, also call it home. Since fungi are so diverse, two distinct fungi may have genetic differences comparable to those between a person and a fish.
- Eukarya are eukaryotes, which have organelles and nuclei that are bound to membranes. Prokaryotes are older, less numerous, and simpler than eukaryotes.
- Eukarya refers to creatures with nuclei in their cells. Additionally, it is the only realm in which multicellular observable organisms, such as people, animals, plants, and trees, exist. Achaea and bacteria are unicellular organisms without nuclei.

The domain containing all
organisms with eukaryotic cells is the Domain Eukarya. There are only three
domains; the Archaea, Bacteria and Eukarya. Domain Eukarya came from the first
prokaryotic cells billions of years ago.
Answer:
1) Recursive definition:
2) At the beginning of the 4th interval
Explanation:
1)
The initial population of the bacteria at time zero is
Here we are told that the reading is taken every two hours; we call this time interval "n", so
And also, after every time interval n, the number of bacteria has tripled.
This means that when n = 1,
And when n=2,
Applied recursively, we get
And substituting p0,
(1)
2)
Here we want to find at the beginning of which interval there are
bacteria.
This means that we can rewrite eq.(1) as
By simplifying,
Which means that
However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
