I think it's radioactivity. From what I learned in 5th grade, the hardness of a mineral can be a major indicator, as a diamond is the strongest mineral, and talc is extremely easy to break down (I think it's Talc at least). A quick google search showed no mention of radioactivity. Also radioactivity just doesn't sound right compared to the other answers.
It's been a while since I've gone over it so I could be wrong.
Answer:
B. olfactory information is not integrated in the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
Explanation:
The thalamus is the main source of sensory information to the primary sensory cortex except for the sense of smell. The olfactory information from the sensory neurons needs to pass through the thalamus in order to reach the primary sensory cortex. Moreover, different thalamic nuclei, i.e., different groups of packed neuronal cell bodies that form the thalamus, have been involved in language. A bilateral thalamic activation (with left greater than right thalamic activation), as well as the activation of cortical regions associated with the language, is observed during tasks related to language processing. Language information is processed within the left hemisphere, while the olfactory information is processed in the olfactory bulb which is located on the inferior (bottom) side of the cerebral hemispheres.
I think the answer is transfer RNA
The process that breaks down rocks and other subtance is called Weathering and erosion.
