Answer:
All of the above, option D.
Explanation:
The title of the research conducted by W.J Strawbridge and three other colleagues (namely; H.R Higby, S.J Shema and J.L Balfour) is ''Antecedents of Frailty Over Three Decades in an Older Cohort''. The research focus more on how old people within the ages of 65 and 102, and that old people tends to lose their abilities to do things they used to do while they were still young because of Frailty and also, because of the habits that people had before they turn to old adult such as smoking and heavy drinking, also, with all the three options (that is ''A'' to 'C') in the question are correct.
Answer:
The correct answer will be option-C
Explanation:
In an organism, the mechanism of gas exchange depends on the partial pressure and total pressure of the gas. Partial pressure is the pressure of the gas exerted by a single type of gas in a mixture of gases and this pressure determines the movement of gases in the system.
The diffusion of the oxygen from the alveoli to blood capillaries depends on the partial pressure as the partial pressure of oxygen is high in alveoli measured about 104 mmHg compared to the capillaries measured about 40 mmHg.
This difference in the pressure generates pressure gradient which leads to the movement of the oxygen from alveoli to the capillaries as the movement takes place from higher to lower concentration gradient.
Thus, Option-C is the correct answer.
