Hi , a scientific concept is a scientific theory or law that explains why and how a natural event or process occurs.
Conifers.
Or gymnosperms, depending on what "this plant" is.
Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.
Explanation:
The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.
The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:
--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes
--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.
--> Resistance of the skin to invasion by organisms
While examples of innate cellular and chemical defenses include:
--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System
--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.
--> basic polypeptides which react and inactivate certain types of gram- positive bacteria
-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.
In the diagnostic statement "Chronic allergic sinusitis due to animal dander",the modifying terms are;
CHRONIC AND ALLERGIC.
A diagnostic statement states the potential and actual health problem of a client. These client's problems are the ones the nurse or the person making the diagnosis can actually identify easily and also for which order and implement nursing interventions inorder to maintain the health status if the client,and to eliminate, prevent or rather reduce changes and alterations in the patient's health status.
So from the question given, the modifying terms from the diagnostic statement "Chronic Allergic Sinusitis" is Chronic and Allergic.
Water resources are sources of water that are potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. The majority of human uses require fresh water.
