Pseudomonas aeruginosa organism would probably survive in a hot tub. So the correct option is D.
The organism most likely to survive in a hot tub is Pseudomonas aeruginosa. This is because Pseudomonas aeruginosa is a common waterborne bacterium that can survive in a wide range of environments, including warm water. It is also resistant to many disinfectants, making it difficult to eliminate from water sources.
On the other hand, E. coli is a bacterium that is commonly found in the intestines of warm-blooded animals and humans and may indicate fecal contamination in water. Vibrio cholera and Entamoeba histolytica are both waterborne pathogens that can cause severe gastrointestinal illness in humans and are unlikely to survive in hot tub temperatures.

Tetrapods were no longer tied to the water for reproduction is believed to be the most significant result of the evolution of the amniotic egg. The amniotic egg, which evolved in reptiles, birds, and mammals.
Allowed embryos to develop outside of water and therefore enabled tetrapods(four-limbed animals) to move onto land and occupy terrestrial habitats. The amniotic egg is a complex structure consisting of several membranes that protect and nourish the developing embryo. These membranes include the amnion, which encloses the embryo in a fluid-filled sac; the chorion, which allows gas exchange; and the allantois, which stores waste products. The earliest known amniotic egg dates back to around 312 million years ago, during the Carboniferous period. This egg belonged to an extinct reptile called Hylonomus, which was about the size of a modern-day lizard. The evolution of amniotic eggs allowed reptiles, birds, and mammals to diversify and occupy a wide range of habitats. Some reptiles, such as snakes and lizards, evolved specialized forms of the amniotic egg that allowed them to lay eggs in burrows or nests, while others, such as crocodiles and turtles, developed the ability to lay eggs on land. Birds, which evolved from a group of small, feathered dinosaurs called theropods, inherited the amniotic egg from their reptilian ancestors. However, birds have modified the structure of the egg to allow for the development of a hard, calcified shell, which helps to protect the egg from damage. Mammals also evolved from reptilian ancestors and originally laid amniotic eggs.

Sea Lions are expected to show the highest concentrations of DDT and other chlorinated hydrocarbons in its tissues.
D is the correct answer.
DDT has a propensity to accumulate in animals as a result of its chemical characteristics. DDT builds accumulated in the fatty tissues of predators as lower-level creatures on the food chain are consumed by animals higher up the food chain.
In the top carnivore, the concentrations will be at their highest. This is due to the fact that consumers at each subsequent trophic level eat more than at the level before them in order to meet their energy needs. As a result, DDT keeps building up at increasing quantities in the subsequent trophic levels.
