The greenhouse effect is a natural process traps heat in the atmosphere - global warming tends to be when additional greenhouse gases are released into the atmosphere and this causes a warming event.
The correct answer is a. Complex
A complex or undefined medium is rich in nutrients, which contain water-soluble extracts of plant or animal tissue, a sugar, (often glucose is added to serve as the main carbon and energy source). The combination of extracts and sugar creates a medium which is rich in minerals and organic nutrients, but the exact composition is unknown.

IF:
Number of cells:

DNA lenght:

Distance from Earth to Sun:

Then:
a) <span>Over how many miles would the total DNA from the average human stretch?
The answer is product of multiplication of the number of cells (C) and the DNA length (D):
Total DNA: </span>

⇒

⇒

⇒
The total DNA from the average human will stretch 
b) How many times would the total DNA from the average human stretch from Earth to the Sun and back?
The answer is concluded from the ratio of the total DNA length (T) and the <em>twice </em>(because of stretch to the Sun and back, thus, <em>two directions</em>) of distance from <span>Earth to the Sun (ES) and :
Ratio: </span>

⇒

⇒

⇒

<span> ⇒

</span><span> ⇒ [tex]R = 667.7
</span>
Thus, 667,7 times will the <span>
total DNA from the average human stretch from Earth to the Sun and back.</span>
Answer: Somatosensory cortex.
Explanation: The somatosensory cortex receives all sensory input from the body. The somatosensory system is a part of the <u>sensory nervous system</u>. These sensory receptor cells are activated by different stimuli such as heat and nociception, giving a functional name to the responding <u>sensory neuron</u>, such as a thermoreceptor which carries information about temperature changes.
