Part I
Brightness, saturation, and hue are vision's three primary dimensions. Firstly, brightness refers to the light intensity that a specific object reflects and connects to the light wavelength's amplitude. The more light an object reflects, the more the potential to appear brighter. However, Alipour and colleagues (2019) state that light wavelengths impact color intensity. For example, yellow can seem brighter than red and blue, yet the three colors are the same. Although light lacks color, people get brightness and color perceptions due to the nervous system and eyes. Secondly, saturation denotes light's colorfulness. It illustrates how wide or narrow light wavelengths can be—for instance, pure light associates with one wavelength. White light lacks saturation since it has all light colors. Black is unsaturated since it lacks light. Some colors are duller than others due to the sight of lightwave combinations. Thirdly, hue defines light wavelength. For instance, shorter waves are blue and violet, while the longer ones are red and orange. A combination of all visual wavelengths creates white light.

Question 5
           Serin and Tek (2019) claim that circadian rhythms are biological in nature and always happen daily. Specifically, it is an action that occurs in people, plants, and even animals as an approach to dealing with the Earth's movement. Similarly, the living things possess a biological clock, a timing tool for dealing with the changes that the living organisms experience. The primary role of the clock is to sustain the rhythms of the plants, animals, and human beings to regulate how they use and store their nutrients appropriately. The activity happens in the body at the molecular level. According to Serin and Tek (2019), human beings and organisms require to experience daylight to preserve the body's biological clock. It also affects activities happening during the day. Sleeping and waking up adjust due to light-dark cycles occurring every day. Circadian rhythms and biological clocks are critically significant in every living creature's body because there is a close connection between these two aspects and health issues. For instance, when biological clocks are absent or fail to work appropriately, there is a likelihood that the victims will suffer many health conditions. Examples include depression, mental complications, and obesity, which might increase distractions in the body's biological clock.
Question 6
           Sensation occurs in cells of different organs in human beings and even animals. For instance, it occurs in cells of the skin, nose, eyes, or tongue. When individuals sense any energy that physical objects generate, we call it sensation. However, perception denotes menta...
