Answer
The correct option is B.
Reason
A brief technical explanation for each option is given below.
a. Asthma
It is lower respiratory disorder in which air passage way become narrow and swells, produce extra mucus which make difficulty in breathing, and trigger sneezing, wheezing and shortness of breath.
b. Pleurisy
It is lung disease in while pleura, lining of lung and chest cavity become inflamed due to accumulation of pleural fluid. The fluid is accumulated through the process of pleural effusion which may be transudate or exudate.
c. Pulmonary hypertension
It is a condition in which blood pressure increase in lung arteries. It leads to shortness of breath, swelling of legs and fast heartbeat.
d. COPD
Stand for chronic obstructive pulmonary disorder. It is a progressive lung disorder accompanied with chronic bronchitis, emphysema and non-reversible asthma.
e. Emphysema
In this type of lung disorder the alveoli block due to accumulation of fluid in it, that result into low exchange of gases (oxygen and carbon dioxide).
The amplification of the signal from a water-soluble hormone is achieved through an increase in <span>cAMP in the cytoplasm
cAMP plays an important role as messenger in producing protein&enzyme in our body.It gave a signal to Water soluble hormone that acts as a binder that bind all the amino acids to form proteins to amplify and operate</span>
Answer: Atmospheric Nitrogen is unreactive
Explanation:
The atmosphere is made up of about 80% Nitrogen, 16% oxygen, about 4% carbon dioxide, rare gases etc.
However, the 80% Nitrogen is highly unreactive, and needs to be trapped by competent micro organisms known as nitrogen-fixing bacteria in the root nodules of legumes.
Then, it is converted to several forms like nitrites, nitrates (easily absorbed by plants), ammonia and finally escape to the atmosphere again.
This brief illustration explains the NITROGEN CYCLE, and it is the only means by which plants and animals can use the highly unreactive nitrogen
Answer:functions
Primary active transport moves ions across a membrane and creates a difference in charge across that membrane. The primary active transport system uses ATP to move a substance, such as an ion, into the cell, and often at the same time, a second substance is moved out of the cell.
