Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower.
The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination.
In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.
<h3><u>Answer</u>;</h3>
Key
A sorting device that is useful in classifying by observation is a <u>key</u>.
<h3><u>Explanation</u>;</h3>
- <em><u>Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms. </u></em>
- They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
- Therefore<u><em>, keys can be used to identify a living organism or determine which group it belongs to</em></u> by answering questions on the key about characteristics of living things.
