Science Discoveries of 2020

In 2020, despite the pandemic, significant scientific discoveries were made. Researchers found evidence that Spinosaurus was likely aquatic, using fossils from Morocco. Whale shark ages were determined using nuclear residue from Cold War tests, revealing they grow slower and live longer than thought. Malaria parasites were found to have their own biological clocks, independent of their hosts. These findings enhance our understanding of natural history and disease, showcasing the dedication of scientists in various fields.

What was the main focus of people's minds in 2020 according to the video?

• Space exploration

• The pandemic

• Climate change

What significant feature of Spinosaurus egypticus suggests it might have been aquatic?

• Its ability to fly

• Its herbivorous diet

• Its long, narrow jaws and croc-like teeth

• Its large size

What was the key evidence that supported the aquatic nature of Spinosaurus?

• Fossils found in Antarctica

• Skull fragments found in Asia

• Tail bones discovered in Morocco

• Footprints found in Australia

How did scientists determine the age of whale sharks?

• By measuring their length

• By observing their behavior

• By analyzing their teeth

• By using nuclear residue from Cold War tests

What did the research reveal about the growth and lifespan of whale sharks?

• Their growth rate is unpredictable

• They grow slowly and live longer than previously thought

• They grow quickly and have a short lifespan

• They stop growing after a certain age

What triggers the regular recurring fevers in malaria?

• The host's immune response

• The host's physical activity

• The synchronized release of parasites and waste materials

• The host's diet

What did scientists discover about the biological clock of malaria parasites?

• Their clock is influenced by external temperature

• They rely solely on the host's circadian rhythm

• They have their own biological clock

• They do not have any biological clock

What was the method used to study the malaria parasites' biological clock?

• Analyzing their genetic material

• Studying them in a laboratory environment
