Answer:
The digestion of carbohydrates begins in the mouth and ends in the small intestine.
Explanation:
The absorption of carbohydrates, depending on whether they are simple or complex, will begin their digestion in the mouth by the action of saliva in food, where starches are initially separated; Once this food bolus reaches the stomach, the hydrochloric acid acts, to end later in the small intestine. Amylase, a component of pancreatic juice, ends the digestive process of carbohydrates by transforming starches into maltose, which are then transformed into monisacarides (glucose, galactose, fructose), which is the way they are absorbed by the body. In the liver they are again transformed into glucose.
Answer:
The “lub” is the first heart sound, commonly termed S1, and is caused by turbulence caused by the closure of mitral and tricuspid valves at the start of systole. The second sound,” dub” or S2, is caused by the closure of aortic and pulmonic valves, marking the end of systole.
Answer:
<em>Pulmonary surfactant.</em>
Explanation:
It is essential for life as it lines the alveoli to lower surface tension, thereby preventing atelectasis (a complete or partial collapse of the entire lung or area (lobe) of the lung) during breathing.
Answer:
10 per 1,000.
Explanation:
The death rate and birth rate affects the population dynamics of the particular area. The birth rate increases the population size whereas the death rate decreases the population size.
The death rate of a population can be calculated by the following formula:
Crude death rate = total death/ total population
Here, total death = 1,000 and total population = 100,000.
Crude death rate = 1,000/ 100,000 = 0.01 or 10 per 1,000.
Thus, the correct answer is option (c).
