Why Are Antarctic Sea Spiders So Big? - Field Trip

The video explores metabolism and aging, featuring Dr. Art Woods from the University of Montana. It covers the definition and trends of metabolism, the role of oxygen in energy extraction, and the unique metabolic capabilities of insects. The etymology of the word 'metabolism' is discussed, followed by a focus on temperature's impact on metabolism, particularly in polar regions. The concept of polar gigantism in marine invertebrates is examined, highlighting the effects of climate change on these organisms.

What is Dr. Art Woods' primary area of research?

• Marine biology

• Insect physiology

• Plant ecology

• Human anatomy

How is metabolism defined in the context of biology?

• The rate of oxygen consumption in mammals

• The sum of all energy transformations in an organism

• The process of photosynthesis in plants

• The growth rate of an organism

Which organisms are known to have the highest aerobic scopes?

• Birds

• Reptiles

• Insects

• Whales

Why is oxygen crucial in the process of metabolism?

• It is used to build muscle tissue

• It is the primary source of energy

• It serves as the final electron acceptor in energy production

• It acts as a catalyst in photosynthesis

What system do insects use to deliver oxygen efficiently to their muscles?

• Circulatory system

• Digestive system

• Tracheal system

• Respiratory system

What is polar gigantism?

• A growth pattern observed in tropical fish

• A phenomenon where polar animals are smaller than their relatives

• A type of climate change effect on polar bears

• A condition where marine invertebrates near the poles are larger than their relatives

How might climate change affect the metabolism of sea spiders?

• It will cause them to migrate to warmer waters

• It will increase their metabolic rates significantly

• It will have no effect on their metabolism

• It will decrease their metabolic rates
