Role of stomach and small intestine during digestion in humans
Answers
Explanation:
Oil and natural gas are non-renewable sources of energy. There have been numerous attempts to minimize the depletion of these two resources. Scientists have proposed many reasons for the high importance of their conservation.
Oil and natural gas conservation involves the use of these resources in a better and a more well-organized manner with respect to economic, social and ambient expenses and rewards, contributing to more efficient energy utilization practices and the reduction of the damage dealt to the ecosystem.
This article evaluates the ways in which oil and natural gas can be conserved, and describes the expected results of these conservation measures.
Conservation of oil and natural gas remains a problem in many countries around the world. One of the most evident proofs of this is a global increase in its price.
Consequently, each of us faces the responsibility of conserving these scarce resources. This involves the support of governmental oil and natural gas protection policies. Every single family should carry the responsibility of conserving state-owned resources.
In order to control the use of oil and natural gas, governments should implement a number of policies. Moreover, motor vehicle users should be obliged to make sure that their vehicles’ tires are sufficiently inflated. The condition of the tires should be checked at least once a month. By doing this, fuel consumption is decreased by about 3%.
Vehicle users should also plan their route in advance. If possible, people should consider other means of transportation: riding a bicycle, walking or taking a bus whenever possible.
Another important method of energy resource conservation is the consistency of the vehicle’s speed. Statistics show that fuel consumption decreases greatly when one drives at the speed of about 60 km/h. At the same time, lower speed is a safety measure. Drivers are also advised to use air conditioners, as this decreases fuel consumption while driving at high speeds, especially on the highway where the road is smooth.
Answer:
Digestion of Carbohydrates in the small intestine: In response to the action of stimuli received from the vagus nerve (10th carnial nerve) and secretin (a gastrointestinal hormone), the Brunner’s gland (compound tubular glands of the duodenal epithelium) secretes a large amount of viscous, enzyme-free, alkaline and watery mucoid fluid.
