Answer:
- Humans don't have the enzyme to digest the bonds between monosaccarides that make up fiber
- fiber contains potential energy
Explanation:
Dietary fiber (FD): edible part of plants that resists digestion and absorption in the small intestine and undergoes partial or total fermentation in the large intestine. Its role in intestinal function is the criterion that has been used to establish the recommendations. It is considered that an intake of 25-30 g / day of FD (14 g / 1,000 kcal), from food - not from supplements - and from different sources, is the recommended amount. The desirable ratio between insoluble / soluble fiber is 3/1. Food fiber, according to its chemical characteristics and its effects on the human body, is classified as soluble fiber and insoluble fiber.
The soluble fiber has a branched structure that allows it to retain water forming gels. It is very fermentable because of the intestinal flora, capable of producing a large amount of volatile fatty acids (acetate, butyrate, propionate). It helps to increase the fecal bolus, increasing the bacterial mass. Within this type of fiber is inulin, pectins, gums and fructooligosaccharides. It is the type of fiber that predominates in legumes, in cereals such as oats and barley and in some fruits.
Insoluble fiber captures little water, is not fermentable by the intestinal microbiota and its mixtures have low viscosity. Decreases the viscosity of the bolus and the intestinal transit time. This type of fiber is very useful in preventing constipation. Ex .: cellulose, hemicellulose, lignin and resistant starch. It is the type of fiber that predominates in wheat bran, whole grains, some vegetables and in general, in all cereals.
The fiber being composed of monosaccharides of monosaccharides could potentially be used as energy if the polysaccharides constituting the fiber could be degraded.
Answer:
B: Warm to Cool with the wavy arrows
Explanation:
Radiation travels from warm objects to cool objects
I Think The answer is b I hope it helps
Answer:
B
Explanation:
For metals, the further away the valence electrons are from the nucleus, the higher the reactivity of the elements. Unlike halogens that are more reactive if the valence orbital shells are closer to the nucleus. This is due to ionization energies – which is the minimum energy required to discharge an electron from its orbit.
For metals this should be lower because they need to lose electrons to attain a stable electron configuration. For halogens it should be high because they don't need to lose electrons, but rather gain, in order to attain stable electron configuration.
Electrons in their orbital shells need to occur in pairs (with opposite quantum states) to be in stable configuration and as long as an atom has orbitals with single electrons, the atoms will be reactive as opposed to when its orbitals are ‘full’.
Solarimeters are the instruments that measure solar radiation
