Answer : Binary Fission which grows exponentially.
Explanation : Binary fission actually means binary - consisting two and fission - cleavage into halves. It is one of the modes of asexual reproduction.
This type of fission is majorly observed in the asexual reproduction in prokaryotes. It is rarely seen in some some single-celled Eukaryotes like Amoeba and Paramecium.
Also, In binary fission there is DNA replication and segregation which occurs simultaneously.
This increases the graph exponentially as the growth gets faster and faster with the passing period of time.
A reference image of binary fission is attached in the answer.
No, it is not alive because water is a non-living thing. Aka it doesn't have cells or organs. The fact that it rolls up on the beach all depends on wind and the gravitational pull of the Earth.
Answer:
convergent evolution
Explanation:
If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.
It's an animal cell because it doesn't have a cell wall or chloroplasts. It's also not rectanglular shaped. :)
They all develop gills, slits and tails
