Answer:
Do u mean in A level or GCSE'S?
The answer is thirteen.
STR stands for <u>s</u>hort <u>t</u>andem <u>r</u>epeats. In this analysis, highly polymorphic regions with short tandem repeats are used. In FBI investigation, thirteen regions are analyzed and compared. The chance for two people to have the exact same thirteen regions is almost impossible (1 : 1 billion or less). This way a difference between two DNA profiles could be assessed.
Answer:
Explanation:
(A) PaO₂ below normal: PaO₂ is used to describe the partial pressure of oxygen dissolved in the blood. When it is below normal, it indicates the individual isn't getting enough oxygen hence there is low pressure of dissolved oxygen in the blood. This sign/symptom falls under the Respiratory/oxygenation data cluster.
(B) Dyspnea on exertion: Dyspnea is a term used to describe shortness of breath while dyspnea on exertion is when an individual runs out of breath as a result of not been able to breath deeply/properly during or after an exercise. This sign/symptom also falls under the Respiration/oxygenation data cluster.
(C) Productive cough: This is a type of cough that produces/forces mucus out of the airway (thereby clearing the airway). This sign/symptom from this description is also Respiratory/oxygenation data cluster.
(D) Oxygenation saturation 92%: Oxygen saturation is when the body can supply enough oxygen to the cells and tissues within it's system. This sign/symptom is also a Respiratory/oxygenation data cluster.
(E) Feels "too tired to do much": This can also be referred to as fatigue. This is usually as a result of inadequate energy produced (usually from glycolysis) in the body. This sign/symptom, from this description, is a Reduced energy level data cluster.
(F) Requires frequent rest periods: This usually occurs as a result of imbalance in the body's metabolism. Here, the body uses more energy than it produces; more anabolic processes (energy requiring) than catabolic processes (energy produced/released). This sign/symptom, from this description, is a Reduced energy level data cluster.
Answer:
Proximal convoluted tubule
Explanation:
The major work of re-absorption is carried out in nephron by the proximal convoluted tubule (PCT). The PCT re-absorbs all the essential nutrients such as amino acid, potassium, glucose etc. and water driven by passive transfer based on concentration gradient. Along with gradient, pH of the urine also affects the re-absorption. Based on the pH of the urine (basic or acid), re-absorption of ionized acid increases or decreases.
I believe it is 'white fur' because living in the Tundra means it is snowing. Snow is white, so basically, the white fur is specifically for the Tundra.
I hope it helps.
