Answer:

The bag will get smaller

Explanation:

Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.

An infant has a strange rash. Some of the rash is swabbed and examined under the microscope. A mass of threadlike structures is observed. So, this infection be treated with an anti-fungal cream

OTC creams will deal with the infection (e.g., Lamisil, Lotrimin, Micatin, Tinactin), however, in some cases oral drugs are fundamental.

In infants, Fungi can cause superficial infection, i.e., on skin, nails, and hair like oral thrush, candida diaper rash, fungal infection, and so forth, are different kinds of superficial fungal infections, subcutaneous contagious disease in tissues under the skin and finally it causes systemic infection in more profound tissues.

The primary structure of most fungi consists of fine, spreading, normally dull threads like structures called hyphae. Every fungus will have immense quantities of these hyphae, all interlacing to make up a tangled web called the mycelium.

Fiesta28 [93]

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
