Bio 110 – Principles of Biology I
● To understand biology one must use “evidence-based” teaching and learning approaches.
● Covalent bond : sharing of an electron between two atoms.
● 98% of most living organisms are composed of six atoms.
● Carbon is the versatile atom because it forms 4 covalent bonds
● Each of the six atoms form a specific number of covalent bonds.
●
○ Covalent bonds in which the electrons are not equally shared - polar bonds
○ Polar covalent bonds almost always involve Oxygen
○ Almost all other bonds are non-polar

2.
○ H-bonds contribute to the complex structure of many biological molecules
○ -water has many unique properties because energy is required to break these H
bonds between molecules
○ - Water has a high heat capacity.

Document Summary
To understand biology one must use evidence-based teaching and learning approaches. Covalent bond : sharing of an electron between two atoms. 98% of most living organisms are composed of six atoms. Carbon is the versatile atom because it forms 4 covalent bonds. Each of the six atoms form a specific number of covalent bonds. Covalent bonds in which the electrons are not equally shared - polar bonds. Polar covalent bonds almost always involve oxygen. H-bonds contribute to the complex structure of many biological molecules. Water has many unique properties because energy is required to break these h bonds between molecules. Water has a high heat capacity. Adhesion and cohesion allow water to be pulled from the roots to the leaves of plants. H bonds can"t form with non-polar molecules. Ice is less dense than water, which is essential for life. Water: more h bonds form as the temperature is lowered.
