What new evidence helped scientists understand that Spinosaurus was a fully aquatic dinosaur?

• Its long, narrow jaws and crocodile-like teeth.

• Fossils of its tailbones, which were long, flat, and strong.

• Its ability to hunt along rivers in Northern Africa.

• The accidental destruction of previous fossils in World War II.

How did scientists accurately determine the age of whale sharks?

• By observing their growth patterns in controlled environments.

• By comparing growth bands in their vertebrae to tree rings.

• By analyzing Carbon-14 levels in their bones from nuclear weapon tests.

• By tracking individual whale sharks over many years.

What is the main reason malaria patients experience regular recurring fevers?

• The body's immune system fighting off the infection.

• The parasites entering and breeding inside red blood cells, then bursting out.

• The host's circadian rhythm being disrupted by the parasite.

• The mosquito bite itself causing an allergic reaction.

Recent research suggests that malaria parasites time their fever-causing cycles using what mechanism?

• The host's daily internal clock.

• Their own internal biological clock.

• Environmental cues like light and darkness.

• The availability of red blood cells to infect.
