Perception of physical world through the brain. Introduction: Physical world has the light and sound of different wavelengths and frequencies. The sounds, textures and colors are perceived with the help of sensory receptors in the eyes and ears, which convey the information to the brain. These receptors act as energy filters which change the various forms of energy in the real world into the nerve impulses energy. This in turn, gives rise to different forms of sensations that help us relate to the physical reality, even if it is indirect or incomplete.

Perception of physical world through the brain.

Introduction:

Physical world has the light and sound of different wavelengths and frequencies. The sounds, textures and colors are perceived with the help of sensory receptors in the eyes and ears, which convey the information to the brain. These receptors act as energy filters which change the various forms of energy in the real world into the nerve impulses energy. This in turn, gives rise to different forms of sensations that help us relate to the physical reality, even if it is indirect or incomplete.

Expert Solution & Answer

Explanation of Solution

Human perception of the reality is limited by the ability of sensory receptors for example, the same impulse received by the auditory and optic nerve will be perceived as the sound and sight respectively. In case of vision, the environment has Xâ€“rays, electromagnetic waves and radio waves yet; humans are only able to perceive the visible light with seven colors. This is hence, the perception of light in the physical world, which is incomplete.

Another example is human perception of cold, which happens with the help of sensory receptors in the brain that sense different levels of heat. In the real world, there are only degrees of heat. These two functions are evolutionary adaptations that help us cope with changes in the environment for example, dressing appropriately, if it gets colder and protecting ourselves with the help of sense of sight.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
