The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.
The intima, the innermost layer, provides a smooth surface for blood to flow across. The media, the middle layer with muscle and elastic fibers, allows the aorta to expand and contract with each heartbeat. The adventitia, the outer layer, provides additional support and structure to the aorta.
What is the major function of the large artery and how does its structure enable it...

1. Describe the quaternary structure of hemoglobin. How does its quaternary structure enable it to fulfill its biological function? How would its function be affected if a mutation caused its subunits to dissociate? 2. Biomolecules are often symmetrical. What symmetry operations (that is, rotation, inversion, translation, etc.) are associated with the following: a) dyad symmetry b) n-fold symmetry c) mirror symmetry d) dihedral symmetry e) helical symmetry 3. a) Describe the A, B, and Z conformations of DNA b) Besides...
1. How does the structure of Gal4p relate to its function? Make sure to include the structure and function of Gla4p in your answer.
What is transpiration? how does it work, what is its function? What tissue accomplishes this? What is translocation? how does it work, what is its function? What tissue accomplishes this? Xylem/phloem function and structure. Tension/cohesion model of transpiration (capillary action/evaporation). Why does water get pulled upward? How do leaves function in transpiration? How stomata function in transpiration – why there were more stomata on the bottom of the leaf than on the top?
How does the structure and properties of an organic molecular impact its function for a cell or tissue? (consider different types of lipids and amino acids/protein structure). Explain five examples.
how does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant
How does a coronary artery bypass address the problem of a blocked artery? Why is it often not a permanent solution?
Consider the structure and function of each of these four biological macromolecules. How does the structure of each molecule affect its function? For example, in complex carbohydrates, why would long chains of glucose be more effective for energy storage than single glucose molecules? How do the four levels of protein structure affect the shape of enzymes and why is this important for enzyme function? Explain the "lock and key" model of enzyme function using the terms substrate, active site, and...
