All proteins have a primary structure. fibrous and globular proteins have a secondary structure: α helix or β pleated. globular proteins also have a tertiary structure due to interactions of amino acid side chains with water. most globular proteins, including hemoglobin also have a quaternary structure. which of these structures is due to h bonding between amino acid chains?

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
