The human gut microbiome is a collection of microbes that are necessary for proper function of the digestive system and that con

tribute to the overall health of the individual. Infants are colonized with these microbes at birth and their nutrition in the early days of life is important for supporting growth of these microbes. Milk sugars are important in development of the microbiome. Which of the following best explains how both lacto-N-tetraose and lacto-N-fucopentaose could contribute to proper development of an infant's microbiome?

Answer: Gut microbiome degrade the ingested milk sugars through a biochemical pathway, producing ATP required for the energy needs of infant.

Explanation:

The human breast milk fed on by infants  contains a high concentration of indigestible oligosaccharides which include lacto-N-tetraose and lacto-N-fucopentaose.

These milk sugars are utilized by microbes in the gut of infants, yielding lactate as the final product of metabolism and releasing several molecules of ATP as useful energy for use by the infant.

Thus, the presence of these gut microbes at birth, and the feeding of infant with breast milk is vital to fulfilling their energy needs

Consider a field plot containing 200 kg of plant material. Approximately how many kg of carnivore production can be supported? A
mixas84 [53]

Answer:

E) 2

Explanation:

The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.

Which one of the following statements is true of enzyme catalysts? A) Their catalytic activity is independent of pH. B) They are
muminat

Answer:

D) They can increase the reaction rate for a given reaction by a thousand-fold or more.

Explanation:

Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.

What type of monomers are combined to form carbohydrates?.
Illusion [34]
Saccharides are the monomers which are combined to form carbohydrates.

Depending on the type of carbohydrate, the monomer components can be monosaccharides, disaccharide, polysaccharide, etc.

E.g: Sucrose is a carbohydrate (specifically a dissacharide) that is made of glucose and fructose monosaccharides.

Another example is cellulose, which is a carbohydrate (specifically a polysaccharide) that is made of beta glucose monosaccharide components combined together.
