Animal Biology Flashcard

Front

What significant change occurred in the oceans during the Mesozoic Era?

Back

Formation of the first coral reefs.

Front

What did some primate species in Africa adapt to during the Cenozoic Era?

Back

Open woodlands and savannas.

Front

What evolutionary advantage is provided by the presence of a coelom in animals?

Back

Greater flexibility and movement.

Front

Which animals evolved flight during the Mesozoic Era?

Back

Pterosaurs and birds.

Front

What is the function of the central nervous system in bilateral animals?

Back

To coordinate complex movements.

Front

Define the Mesozoic Era.

Back

A geological era known as the 'Age of Reptiles', spanning from about 252 to 66 million years ago.

Front

What are coral reefs and why are they significant?

Back

Coral reefs are underwater structures made from calcium carbonate secreted by corals; they provide habitat for diverse marine life.

Front

Explain the concept of adaptation in animals.

Back

Adaptation refers to the process by which a species becomes better suited to its environment through evolutionary changes.

Front

What is a coelom and its importance in animal biology?

Back

A coelom is a fluid-filled body cavity that provides space for organs and allows for greater movement and flexibility.

Front

Describe the role of flight in the evolution of birds and pterosaurs.

Back

Flight allowed birds and pterosaurs to exploit new ecological niches, escape predators, and travel long distances.
