<span>The nervous system that controls respiration is called
autonomic because it isn't subject to voluntary control. Autonomic Nervous
System (ANS) is responsible for regulating the functions of the body's internal
organs like the heart, stomach, and intestines. It is a division of
the peripheral nervous system that acts unconsciously and it regulates
bodily functions like heart rate, digestion, and respiration. The hypothalamus
is the part of the brain that regulates the Autonomic Nervous System. Other
reflex reactions like coughing, sneezing, swallowing, and vomiting are also
part of autonomic functions that occur in the body.</span>

The electron transport chain is a chemical reaction where electrons are transferred from a high-energy molecule to a low-energy molecule. These reactions can be used to convert energy from sunlight in photosynthesis or extract energy from sugars in respiration.
The study of tree rings is called dendrochronology. Trees produce a single growth ring each year and by studying the size and composition of each ring scientists can get information about the age of the tree, available nutrients in the area, and general climatic conditions. A relatively small ring may indicate a year when there was very little rainfall and a larger ring indicates favourable conditions for plant growth.
Ice cores hold information on past global volcanic activity and past atmospheric conditions. Tiny bubbles in the ice cores give information on the concentration of gases in the atmosphere. Ice core data plays a key role in linking the increase in carbon dioxide concentrations to present day global warming.
