miskamm [114]

Evaporation takes place when the sun's heat breaks the bonds with water in liquid form which happens to be in an ocean, lake, stream , or puddle, it is then draw into the atmosphere while it is in a gaseous state. Transpiration is for lack of a better word, plants sweating. Plants release small amount of water which are then usually evaporated or used by the plant.

Epsom salts are solutes that do not pass through cell membranes. If one soaks in a hypertonic solation of Epsom salts, which of

IceJOKER [234]

Answer:

Explanation:

The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.

In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.

If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)

However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.

aleksley [76]

<h3>Answer;</h3>

produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria

<h3>Explanation;</h3>

Secretions from the highlighted glands produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria 
During inhalation airt that contains dust particles or bacteria or other microorganisms may enter the air ways.
The layer of the airway covering the airways, is rich in antimicrobial compounds and mucins that are responsible for removal bacteria and other microorganisms from the airway .
This layer consist of mucus that traps, kills, and also inactivates the bacteria. It also contains periciliary fluid which keeps mucus at optimum distance from the underlying epithelia, to enhance bacteria clearance and the motility of cilia.
