Why is it important that the mouth and stomach are near the start of the digestive system? thx

Answers

Answer 1
Answer:

Answer: To complete the process of digestion after the food is ingested by mouth.

Explanation:

The food that we eat is ingested by mouth and here the mechanical degradation of food takes place. This breaks down the food into smaller pieces.

Mouth also contains the enzyme that is responsible for the digestion of starch.

Then the food from the mouth reaches the stomach where various types of digestive juices and enzymes are secreted to digested the food.

Hence, mouth and stomach must be near in the digestive system.

Answer 2
Answer: Because the mouth breaks down the food and the stomach uses acid to break food down even more

Which statement about the free enterprise system is true?

Answers

The free enterprise system allows the citizen to own and operate a private business for profit.

The basic principles of a free enterprise system were laid out by Scottish philosopher Adam Smith in an influential book published in 1776: An Inquiry into the Nature and Causes of the Wealth of Nations. The Nobel-prize winning 20th century economist Milton Friedman said of Adam Smith, "The key insight of Adam Smith's Wealth of Nations is misleadingly simple: If an exchange between two parties is voluntary, it will not take place unless both believe they will benefit from it." Smith argued for such voluntary exchanges within a free market system. He labeled the government-manipulated economic system that was prevailing in his day as "mercantilism," a system in which governments specifically authorized some merchants as the official agents of commerce (rather than endorsing free enterprise). The mercantilist system also viewed wealth as though there were a fixed amount of it available in the world, represented by precious metals such as gold and silver, and that nations were in competition over who got more of that fixed amount of world wealth. Smith saw that wealth was something that could be created and increased through voluntary exchange and free enterprise. Smith's ideas formed the basis for what we have come to know as capitalism.

The great Roman Poet, Lucretius wrote, "Things cannot be born from nothing, cannot when begottend brought back to nothing." This statement became an accepted theory as a result of the work of the chemist, Lavoisier in the 18th century. This is the law of conservation of matter. Similarly, the law of conservation of energy is an important law in physics. Can you discuss the validity of the conservation of energy in terms of potential (gravitational or elastic) and kinetic energy by giving real-life applications

Answers

Explanation:

When a swing is at its maximum height, the potential energy, associated with the height, is maximum. At this point its speed is zero, so the kinetic energy is zero. As the swing descends, having less height, the potential energy decreases and the kinetic energy increases. When it passes through the position with the minimum height, the potential energy is minimal and the kinetic energy is maximum.

This is true in the ideal case, in which there is no friction due to air resistance.  When friction is taken into account, implies that the swing stops gradually, since its energy is converted into thermal energy

Which colors has a wavelength shorter than the others?

Answers

Answer: blue, indigo and violet

Explanation: looking at the visible light spectrum, we have

R O Y G B I V

Where R = red , O = orange light, Y = yellow, G = green, B = blue, I = indigo and V = violet.

Towards the right of the spectrum is increasing frequency and energy which implies that red light has the least energy and frequency and violet has the highest energy and frequency.

Also along from left to right of spectrum is decreasing wavelength.

Hence red light has the highest lomgestvand violet has the shortest wavelength.

So we can conclude that the shades of blue that's blue, indigo and violet has the least wavelength.
