Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
A short chain of the cyanobacterial cells found in the Bitter Springs Chert in northern Australia (about 1 billion years old). The bulk of modern genera really resemble cyanobacteria that are closely related to those that are living today. Unlike this fossilized cyanobacterium.
The fact that microorganisms can even leave fossils may surprise you. The oldest cyanobacteria-like fossils, which are among the oldest fossils ever found, are from the Precambrian, but one specific type of bacterium, the cyanobacteria or "blue-green algae," has left a fossil record that extends all the way back to that time. Larger than other bacteria, cyanobacteria have the ability to produce a thick cell wall. More crucially, cyanobacteria have the ability to form enormous, layered structures known as stromatolites or oncolites, depending on whether or not they resemble domes (if round).

Answer:
The correct answer will be option-hypertonic and the cell will shrink in this solution
Explanation:
In the given question, the person drank the water with high salt concentration. The solution with high salt concentration and low water concentration is known as the Hypertonic solution.
When the person drank the water, the red blood cells with a low amount of salt and high amount of water as compared to the salt water lost their water through "osmosis" as the movement is driven by the concentration gradient from high water concentration to low concentration. As a result of this outward movement of water, the cell shrunk and the person died.
Thus, hyper tonic is the correct answer.
False I think lol srry if not false
I believe its the third one not very sure.
