The sophistication of the visual cortex can be simplified through understanding that the neurons found in this region are distinguished by the kind of stimulus that each detects.
There are three major groups of feature detectors in visual cortex. These includes simple cells, complex cells and hypercomplex cells. The simple cells are the most specific since it responds to the geometric characteristics of the stimulus such as the lines of particular width, orientation, angle and position within the visual field. The complex cells are similar to simple cells. What differentiates one from the other is that they respond to the proper stimulus in any position within the receptive visual field. In addition, some of the complex cells respond to particular lines or edges moving in a specific direction opposite the receptive field. Lastly, the hypercomplex cells are responsive to the specific length of the lines. It is believed that the information from all feature detectors conjoin in to result in the visual stimulation perception.
<h3><u>
The following events are identified as chemical weathering:</u></h3>
- The minerals in a marble statue react with water to form acids and pores in the structure.
- The rocks in a region are streaked orange after being exposed to repeated rains.
<em><u>Reason: </u></em>
When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.
In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.
<h3><u>
The following events are identified as Mechanical weathering:</u></h3>
- A piece of rock crumbles after being constantly thrashed by strong waves.
- Industrial runoff forms cracks in a rocky structure in its path.
<em><u>Reason:</u></em>
When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.
In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.

gathering best describes the nature of cellular respiration.
Cellular respiration<span> is a set of metabolic reactions and processes that
take place in the cells of organisms to convert biochemical energy from
nutrients into adenosine triphosphate (ATP), and then release waste products.</span>
