Answer:

Asthma refers to a disease in which swelling of the airways results in the restriction of airflow into and out of the lungs. During the occurrence of an asthma attack, the production of the mucus gets increased, the bronchial tree muscles become constricted, and the inflammation of the air passages lining occurs. This further minimizes the flow of air and generates a kind of wheezing sound.  

The bronchodilators quickly help in relieving the symptoms of acute asthma by opening the airways. The activity of inhaled bronchodilator begins some minutes post inhalation and endures for two to four hours.  

All the kinds of steroids minimize swelling in the airways, which transports air towards the lungs and minimize the generation of mucus produced by the bronchial tubes. This makes one breathe easily.  

The inhaled steroids cure swelling of the airways, and only a very minute concentration of it gets captivated by the body. Thus, these medicines do not seem to result in any kind of serious side effects in a long run.

After watching the video, how would you define the term ecological relationship? Are they always beneficial to organisms involve
dangina [55]

Answer:

There is no video but ecological relationship will be defined on a general note and it is not always beneficial to organisms.

Explanation:

In an ecosystem, organisms of the same or different species tend to interact with one another. This interaction is referred to as ECOLOGICAL RELATIONSHIP between the involved organisms. An ecological relationship can be of different types depending on the effect.

SYMBIOSIS is an ecological relationship between two organisms that interact together. SYMBIOSIS can either be mutualistic (both organisms benefit), parasitic (one organism loses and one gains), or commensalistic (one organism benefits and one neither benefits or loses). Another ecological relationship is PREDATION, where one organism called the PREDATOR feeds on part or all of another organism called PREY in order to obtain energy.

As stated above, some of the organisms involved in an ecological relationship benefits while others lose. Hence, it is not always a beneficial relationship to organisms.
