Regulating the internal environment of a human is achieved by negative feedback; this is a constant process. Conditions within the body changes and receptors detect that change; receptors are found in the skin, around…
A bird’s eye makes up almost 15% of its body’s weight. In comparison, the human eye makes up only about 1% of our body’s weight. A bird’s eye has cones. Researchers who have examined these cones assert that there is a diverse range of colored oil droplets and visual pigments in these cones, and that his means that birds have a very highly developed sense of color recognition. Some species, such as the hummingbird, are believed to be able to see ultraviolet light because the flowers from which they drink the nectar have patterns that are visible only under the ultraviolet light.…

The retina is a light-sensitive layer at the back of the eye that covers about 65 percent of its interior surface. Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve. In the middle of the retina is a small dimple called the fovea or fovea centralis. It is the center of the eye's sharpest vision and the location of most color perception.…
The mechanism of every homeostatic control has three interdependent components; the receptor, which is a sensor that responds to a change (stimuli) in the environment, by sending information through the afferent pathway to the control center1. The second component, which is the control center, is where the information received is assessed and it is determined whether the conditions are in limits1. The final component is the effector; it uses the information provided by the control center to respond to the change1. The information travels along the efferent pathway from control center to the effector this result in a response to the stimuli1.…
Organisms have complex and extraordinary tools for sensing their environments. These tools have been honed to enable them to efficiently navigate the world around them. As a result, each and every organism alive today is the product of natural selection. Over time, this acquired set of skills evolved into the five common senses; sight, smell, touch, hearing, and taste. Taste is one of the most valuable ways an organism can interact with its environment, since the ability to identify and process the chemicals in food provides a wealth of information about the quality of the food being consumed (Yarmolinsky et al. 2009). The various chemicals an organism can perceive are categorized into five options; sour, salty, bitter, sweet, and umami (Chandrashekar…

To overcome this, a very common strategy is to use secondary molecules such as antibodies, to capture the target protein on the surface. An antibody that recognizes the membrane protein of interest can be immobilized covalently on the surface and subsequently capture the target protein when it is injected. Opposite to covalent immobilization, where proteins are immobilized randomly, the availability of monoclonal antibodies directed against specific epitopes on the target protein makes it possible to immobilize proteins in controlled orientations…
