Description

THE ASSIGNMENT:

This assignment it mostly a straight-forward matter of going back to the course material about adaptations to ultraviolet radiation and then showing you understand the material by explaining it clearly and doing a very small amount of applying it to yourself.

DETAILS:

PART A: PLEASE TITLE THIS PART OF YOUR ANSWER "PART A"

Describe as clearly as you can the relationship in humans between ultraviolet (UV) radiation and each of the following, NUMBERING EACH PART OF YOUR ANSWER as follows:

  1. vitamin D
  2. folate
  3. skin cancer

AND, for each of the above, explain their significance for human fitness. That is, why does each of these things matter for the ability of humans to survive and reproduce?

PART B: PLEASE TITLE THIS PART OF YOUR ANSWER "PART B"

Living on the surface of the earth involves exposure to UV radiation. Humans have evolved to adapt to this aspect of their niche. Explain some of these adaptations to UV radiation by doing the following, NUMBERING EACH PART OF YOUR ANSWER as follows:

1) Describe one specific genetic adaptation (a trait that comes from the DNA you inherit) that youhave that you generally share with all humans. What is the adaptation and how, specifically, does it help to increase human fitness?

2) Describe one specific genetic adaptation that you have but that varies among humans, so that it is somewhat different from that of other individuals, but that would allow you to be well-adapted for life in a particular niche. Explain your trait and what that niche is. Evaluate whether you currently live in that niche.

HINT (or, actually just me practically telling you the answer): This is all about variation in skin color and the different niches are different locations on Earth!

3) Describe one specific physiological adaptation that you have the capacity for, that helps you increase your fitness. Under what circumstances does it become important for fitness, and why?

4) Describe one specific cultural behavior that you have learned and that either helps or harms your fitness. In what way does it help or harm fitness?

Please remember that ALL of your above discussion should concern adaptations in relation to exposure to ultraviolet radiation!

ANSWER LENGTH:

This will probably take a couple of double-spaced pages, or more depending on your formatting. Each piece of the answer (A1, A2, A3, B1, B2, B3, B4) will probably take two or three sentences to answer. You'll be better off putting in more detail than less, as long as your details are accurate.


***I just want to make it known that my professor is adamant about no plagiarism and has a zero tolerance policy for all written assignments. It needs to be 100 % original work. Please keep that in mind and do not use any outside sources directly in this assignment (ex: copy & pasting or changing a few words around in a similar document). He inputs all papers through two separate plagiarism detecting softwares. Also, below I have included the rubric for this assignment. Please review it and only request to do this assignment if you feel confident in your ability to get a top score on it. If the work you do is good, I will be using you for many future assignments so please keep that in mind. Thanks!***

Health Implications of UV Radiation
PART A
A1: Relationship between UV radiation and vitamin D.
According to (SunSmart, 2018), vitamin D is a hormone found in the human body, which controls
the level of calcium in the blood. UV radiation is related to vitamin D in that it is one of the
ingredients necessary for its synthesis. Vitamin D is formed from exposure to the sunlight. Sun
rays are responsible for the penetration of UV radiation through the human skin. However, despite
the fact that UV radiation is responsible for the formation of Vitamin D, excess exposure may
result in skin cancer (SunSmart, 2018). Therefore, sunlight prevention measures are important.
Vitamin D is significant in the human body because of necessity in the absorption of calcium,
which forms bones. Vitamin D prevents infections such as rickets in children, depression, weight
gain, skin cancer, and breast cancers.
A2: Relationship between UV radiation and folate.
Folate is also called vitamin B-9. It is a hormone in the blood which responsible for the formation
of red blood cells (Mayo Clinic Staff, 2018). One of the environmental factors affecting folate is
the UV radiation. When a pers...
