Answer:
Analogous structures
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.
In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.
For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.
You are a eukaryote. Your cells are eukaryotic. Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects.
Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Prokaryotes include two groups: bacteria and another group called archaea.
There is a direct relationship between shell color, presence of banding, and habitat because they greatly affect each other in various ways.
<h3>Relationship between shell color, presence of banding, and habitat </h3>
Shell colour shows stronger and more consistent variation with habitat than do banding patterns. Yellow colour shells are present at higher frequencies in open habitats than in woods or closed habitats.
While on the other hand, banding serve as camouflage to protect the organism from bird predators so we can conclude that there is a direct relationship between shell color, presence of banding, and habitat.

The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.
