(a). Based on the figure in the book, From cells to consciousness, the cau nucleus is above the thalamus, and is thus the most superior part of the basal ganglia. Most closely associated to caudate nucleus is the putamen, which is inferolateral to it. These two structures are collectively called the striatum, and inferior to them are the other parts of the basal ganglia: globus pallidus, subthalamic nuclei and substantia nigra. (b). The graph shows the average concentration (mM) of four candidate HD indicators (1-4) in (A) those without the gene variant for HD, (B) asymptomatic carriers, and (C) symptomatic carriers. Results indicate that the concentration of indicator 1 is greatest among group A subjects (around 9 mM) and least among group C individuals (around 7 mM). Lowered levels of indicator 1, around 8 mM, may thus be found in carriers that can pass the gene to its offspring, and further decline may indicate presence of disease. Similarly, the least concentration of indicator 2 is found among symptomatic carriers (around 8 mM), and not much difference is seen between the indicator 2 levels of A and B subjects (around 10 mM). Low levels of chemical 2 may thus be used to diagnose symptomatic HD. On the other hand, no significant difference was found in comparing levels of indicator 3 (around 2 mM) among the three groups. Because levels of chemical 3 remain unchanged between healthy and diseased states, it is not a suitable indicator of HD. Finally, increased levels of indicator 4 (around 6 mM) is observed among group C subjects, and there is not much difference found between the indicator 4 concentrations of group A and group B individuals. This implies that high concentrations of this chemical may indicate symptomatic HD. The graph thus suggests that among the four test chemicals, only 1, 2 and 4 have the potential as an indicator for HD and HD-carriers. (c). (i). Figure 2 shows that concentration of the chemical is inversely proportional to the SLS score, which means that lower levels of indicator X can be found in individuals with higher SLS score, and vice versa. (ii). First, it must be noted that the indicator used must be relatively lower among symptomatic patients than the carriers. Based on figure 1, such relationship can only be seen for indicators 1 and 2. Moreover, the concentration of indicator 2 among carriers is 10 mM. If figure 2 is a plot of indicator 2 levels, then most of the scatter of HD-asymptomatic individuals must be above and below 10 mM. However, as figure 2 shows, only one individual is found to have 10 mM concentration of indicator, and none of the other carriers have levels above 10 mM. Thus, by deduction, figure 2 is a plot of indicator 1 concentrations. (iii). Using the trendline, we can estimate a person with an SLS of 300 to have about 8.2 mM of indicator 1, while a person with an SLS of 550 have around 6.8 mM of indicator 1. (iv). Based on figure 2, a person with an SLS of 300 will most likely be asymptomatic carrier of HD. However, 2 out of 4 subjects with an SLS of 300 have symptoms of HD, so there should be an equal chance for a person with an SLS of 300 to be symptomatic HD. Still, because an SLS of 300 is relatively low, this will most likely present as asymptomatic. On the other hand, a high SLS like 550 will more likely be symptomatic as all subjects with that score manifest with HD. References The Open University, 2006. From cells to consciousness. 2nd ed.

Diabetes and Obesity (Biology)

...?Diabetes and Obesity Diabetes mellitus, commonly referred to as diabetes may be defined as a group of clinical syndromes that are primarily characterized by rise of blood sugar levels above normal limits secondary to insulin deficiency that is either relative or absolute (Votey, 2005). Insulin is the main hormone that prevents abnormal rise in sugar levels. The most common types of diabetes mellitus are diabetes type-1 and diabetes type-2. In type-1 diabetes, the onset of the disease occurs mostly in childhood or adolescence, or even in early adulthood. It occurs as a result of absolute insulin deficiency insulin, due to rampant destruction of cells producing insulin, the beta cells of pancreas. There is a strong genetic... and Obesity...

...? HUMAN BIOLOGY Institute In the context of ageing, research the effects on the body of osteoarthritis and osteoporosis. Osteoarthritis is a pathological condition of the joints which is considered to be the joint pathology presenting with the highest number of cases in the developed countries of the world. It is a condition which restricts the regular everyday activities of the individuals affected. This disease affects the articular cartilage of the joints of the body and leads to their destruction. The most common joint to be affected is the knee joint. The most common cause which is associated primarily with the development of this disease is ageing. It has been analyzed that the onset of the disease begins by the...

...heat production through higher rates of respiration (Taylor, Green, & Stout, 1984). An imbalance in thermoregulation (failure at the receptor/effecter end) can have disastrous effects on the thousands of reactions occurring in the body since each reaction has an optimum temperature (enzymatic activity is maximum at this point) at which the rate of reaction is highest. Any deviation would cause the rate to decrease, thereby affecting the overall body metabolism. In extreme cases, the enzymes in the body may even get denatured. Hence, from the above three examples, it becomes obvious how significant homeostasis is in our lives and how painful it can get because of any disorders associated with the processes.

... Part I – Coffee Shop Wager The hypothesis is: The lady can tell whether milk or coffee was poured into the cupfirst. 2. If only two cups are given to the model, then she will be able to simply freely guess whether the first cup had milk added first or if it is the second one. If there are two cups, it will be easy for her to guess. It is like guessing whether it is going to be heads or tails during a coin toss. One more thing, if there are only two cups, then she can be wrong twice, so there is no chance for her to prove her ability further. 3. I think the model should taste around 12 cups of coffee, because anyway she will not have to drink all of them in order to find out whether milk or coffee was added first. The number... Part I –...

...Response to biology Question: Human Biology Response to biology Question: Human Biology Response to question Whereas it is believed that man evolved from the African Lineage, the view has been challenged on the basis of why people in the Northern Europe do not possess a dark skin. However, this has been effectively accounted based on the Darwin’s evolution theory. According Darwin (1859), the environment plays a crucial role in shaping the behavior and appearance of organisms. As organisms interact with the environment, they become adapted, depending on their demands. The man who went to the North interacted with a set of different environmental conditions that made him to become light-skinned. Response to Question 2 Based... to biology...

Cell biology questions

... Assignment C. what accounts for a reduced mobility of certain integral membrane proteins when examined by fluorescent recovery after photobleaching (FRAP)? It is true that FRAP is one of the most effective means by which lateral diffusion in different types of membrane are measured. It entails absorption of one type of color and release of another color of a certain wavelength. Actually to be precise, it emits a green color which has a certain wavelength after absorbing another color of a different wavelength. The photo bleach results if the absorbed color is intensive whereby that intensity is transferred directly to the dye (Hauser, Seiffert, & Oppermann , 353 – 360). This aspect makes it difficult for the dye to maneuver... Assignment...

Biology - DB 1

...Biology - DB Part A cell being the fundamental unit of life can be differentiated into eukaryotic and prokaryotic cells. The structure and functionality of a cell are made possible by the basic characteristics that form the components of the cell. Eukaryotic cell function at their best through an interplay of action of the organelles that control the functionality of the cell. Nevertheless, despite the absence of the organelles in the prokaryotic cells, the cells are adapted to their functionality at their best. In this regard, a cell can be compared to an organizational set-up equipped with tools and appliances that enables smooth operation and achievement of the objectives of the organization (Kietrys, Szopa, &...

Various experiments are to be conducted to enable an order to regulate the likelihood of either a coin or a dice. Therefore, by the end of the research one should be capable of defining the prospect of a certain gene of a species and that of a penny or a dice no matter how many times they are tossed (Khanna, P. 2010). Keywords: Sample Space Probability in a simple sense can be defined as how occasionally something is bound to happen or the estimated regularity of a specific incident when the experiment is continuous a number of times.
