In the definition of epidemiology, "distribution" refers to: A. Who B. When C. Where D. Why
A. Who B. When C. Where
1. Sirius A, part of the Canis Major constellation, is the brightest star in the night sky. It’s part of a binary system with a white dwarf, Sirius B. The spectrum of light from Sirius B, peaks at a wavelength of 116 nm. The star system is located 8.24 ∗ 1013 km away from Earth. (a) (1 point) What is the frequency of the peak wavelength of light emitted from Sirius B?
2.58 PHz
What is confluence?
the point where the smaller streams flow into the mainstream
What materials are often used in construction?
Acceptable answers are steel, rebar, wood, or concrete.

The study of the distribution and determinants of health-related states in human populations and use of information from those studies to prevent and control disease refers to A. public health B. clinical medicine C. surveillance D. epidemiology
D. epidemiology
1. Sirius A, part of the Canis Major constellation, is the brightest star in the night sky. It’s part of a binary system with a white dwarf, Sirius B. The spectrum of light from Sirius B, peaks at a wavelength of 116 nm. The star system is located 8.24 ∗ 1013 km away from Earth.
What is the energy of this wavelength of light?
1.71 aJ
What is a braided channel?
A river or stream channel is divided into smaller channels by temporary islands called eyots. Tend to form in rivers that have a significant amount of sedimentary load, a steep profile, and where discharge regularly fluctuates.
Explain the difference between isotropic and Anisotropic:
isototropic refers to a material that does not change due to its direction. (Ie. Metal because they do not vary when cut in different directions)
Anisotropic refers to a material that is affected by a change in direction (ie. Wood because the properties of the material will vary with how you cut it, parallel or perpendicular to the grain.)

Epidemiology is often divided into two branches, descriptive epidemiology and analytic epidemiology. Which of these branches addresses person, place and time?
Descriptive epidemiology
Sirius A, part of the Canis Major constellation, is the brightest star in the night sky. It’s part of a binary system with a white dwarf, Sirius B. The spectrum of light from Sirius B, peaks at a wavelength of 116 nm. The star system is located 8.24 ∗ 1013 km away from Earth.
How long does it take for light emitted from the Sirius system to reach Earth?
275 Ms
What is stream order?
a measure of the relative size of streams using the method of assigning a numeric order to links in a stream network

What are dendritic patterns?
A common river drainage pattern that develops in areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions. Examples would be granite, gneiss, volcanic rock, and sedimentary rock that has not been folded.
What are five types of stresses that can impact the structural integrity of a building?
1 compression, 2 tension, 3 shears, 4 bendings, 5 torsions.
Which bird has the fastest running speed (on the ground) ever reached for a flying bird?
Greater Roadrunner
