Or each chromosome of a pair can be individually picked. 16. Explain two ways in which children can have different chromosomes (gene variation) than their mother or father. Random separation of chromosomes (law of segregation) when forming sperm/ova during anaphase I, crossing over of some genes to the homologous chromosomes during prophase I, and mutation during S
Extra glucose cannot be used because of insulin deficiency and and blood glucose level rises, which contributes to further, adding to the osmotic diuresis. 4. What acid-based disturbances commonly occur and why? Arterial blood pH less than 7.30, serum bicarbonate level less than 15 mEq/L (15 mmol/L), and moderate-large ketones in the urine or blood ketones. 5.
10. Describe how the “packaging” of DNA to form a chromosome occurs. How many chromosomes does a human cell have? Why are there chromosome pairs? What are the sex chromosomes for a female?
False Glucose is one of the major electrolytes in plasma. False Both body water and sodium are lost during excessive sweating. True Facilitated diffusion requires a membrane carrier protein and cellular energy. False Ribosomes consist of three subunits of equal size. False An isotonic solution for human red blood cells is a D. 0.9% saline solution.
Therefore, they require an energy-dense diet high in protein, fats, and vitamins. Patients also receive additional A, D, E and K vitamins. Poor absorption also hinders patients’ ability to gain weight and to grow normally. However, the most serious impact of Cystic Fibrosis is still breathing. Doctors can recognize Cystic Fibrosis by testing the salt content of the sweat; it is much higher in people with the disease.
He would see a decrease in urinary output as his kidneys worked to maintain volume in the body. 3. Marks blood pressure was low because his blood vessels had dilated to dissipate heat. His heart rate would vary depending upon what stage he was in. Initially it would rise in an attempt to compensate and hold the blood pressure up, but after awhile the body would tire and his heart rate would fall.
Removing VLCSFA from the diet eliminates any external contribution to the total VLCSFA blood level. Lorenzo’s Oil, made of monounsaturated fatty acids (good fatty acids), causes Competitive Inhibition to occur. The same enzyme complex that elongates fatty acid chains becomes occupied with the production of monounsaturated fatty acids. The enzyme complex cannot produce both types of fatty acids simultaneously. Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA.
Which sex cells join together during fertilization is a random process. New combinations of genes occur, producing genetic variation 2. During meiosis, chromosome pairs sort themselves independently and randomly (this is called random segregation). This produces genetic variation also. 3.
The decisive evidence between water and sports drinks can be further explored through experimenting on the health aspects of an athlete, studying athletic performance, and analyzing post-performance recovery time. With modern athletes trying to reach peak performance, health experiments of different types of nourishment can greatly affect athletes. Dehydration, defined as a body fluid deficit, is one of the biggest perils in exercising (Wilk). “Generally, drinking water is better than drinking nothing, but drinking a properly formulated carbohydrate-electrolyte ‘sports’ drink can allow for even better exercise performance” (Shirreffs). Dr. Susan M. Shirreffs, School of Sport, Exercise and Health Sciences of Loughborough University UK, stated, “After exercise that has resulted in body mass loss due to sweat loss, water and sodium [the most common electrolyte] should be consumed in a quantity greater than the losses to optimize recovery of water and electrolyte balance.” It has been documented that dehydration negatively affects both the cardiovascular function and thermoregulation (Wilk).
The process involves meiosis – having the exact number of chromosomes from both parents (23 from each). It also includes fertilization which fuses two of the gametes and the restoration of the original number. When meiosis occurs the chromosomes of each pair crosses over to create homologous pairs. Most animals (including humans) and plants reproduce sexually. Sexually reproducing organisms have two sets of genes for every trait (called alleles).
