What is the only statement that correctly identifies the ability of different wavelengths of UV light to penetrate the human skin? Note: UVA is the longest wavelength (least energy), and UVC is the shortest wavelength (most energy). If you've studied the electromagnetic spectrum you may remember that wavelength and energy have an inverse relationship. We'll talk more about this later in the course. Group of answer choices A- UVA light penetrates  only as deep as the epidermis, which is where it has its effect   B-UVB light penetrates  only as deep as the epidermis, which is where it has its effect   C-UVC light penetrates  only as deep as the epidermis, which is where it has its effect

Suppose you conduct direct visible spectrophotometry with red fruit punch as your solution. Which wavelengths of light would you expect to be strongly absorbed? Which wavelengths are not strongly absorbed? Explain.

Fill in the blank. The advantages of infrared waves are...? A. that they harden dental fillings and make vitamin D in the body. B. that they provide warmth and read information stored on computer disks. C. that they inspect packaged products and set broken bones. D. that they sterilized medical equipment and kill cancer cells.

Place the following into the correct order to represent the bleaching and regeneration of rhodopsin. Opsin and cis-retinal enzymatically combine to regenerate rhodopsin Trans-retinal is enzymatically converted back to cis-retinal Cis-retinal isomerizes to trans-retinal Trans-retinal separates from opsin Opsin triggers reaction cascade that breaks down cGMP Rhodopsin absorbs photon of light www Next >

discuss the optical properties (delayed light emission) of: 1.) fruit and vegetables 2.) grains

I need to create a process map to reflect the events that take place when light enters the rods after being exposed to dark. (see photo) Just need the order. I can draw the map. I am not sure I ordered them correctly. "Figure 10.32" was not entirely helpful for me here.

Ms. Brundage buys a fancy new plant, and brings it home to replace her plastic ones. The action spectrum of the plant's leaves is found in Figure 1 below. Unfortunately it is winter and there is very little natural light. The local hardware store offers her two lighting choices: halogen light or cool white LED. After a little research, she discovers the spectrum of each type of light, as shown in Figure 2. a) Which type of light should Ms. Brundage purchase? Explain. b)The salesperson assures her that her plant most likely will be able to grow under either type of light. Given what you know about plant pigments and photosynthesis, how could this be possible? Explain.

Tanning properties have a molecular weight of tannin:   a. From 30000 to 100000 b. Above 100000 c. Up to 1000 d. Above 20000 e. From 1000 to 20000

Describe the relationship between melanin and UV light exposure in the human population. Include a description of both the effects of UV light on a person and function of melanin.

1.Explain why UV light can’t be seen by the eye? 2.Explain why we can’t hear sound frequency below the threshold?
