The correct answer is option A.

The immune system safeguards the body against the probable harmful materials by reacting and determining the antigens. Antigens are the components situated on the surface of viruses, cells, bacteria, or fungi. The immune system destructs and determines, or attempts to destroy the components, which comprise antigens.

Nonspecific or innate immunity is the defense system with which an individual is born. It safeguards the person against all the antigens. Innate immunity includes barriers, which keep the harmful substances from getting inside the body. These barriers make the first line of defense in the immune reaction.

Humans deplete the most resources when
Studentka2010 [4]

Answer:

Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.

Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

Xelga [282]

Don the stockings before getting out of bed in the morning.


To prevent distention of the veins, stockings should be applied before the legs are placed in a dependent position. Stockings should be used preventively before the discomfort associated with venous pressure and edema occurs. Knee-high stockings should end 2 inches (5.1 cm) below the knee to avoid popliteal pressure, which limits venous return. Stockings apply uniform pressure. Elastic bandages may slip or develop wrinkles, creating uneven pressure and constriction; edema may result.
