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).
Answer:
Permeability of plasma membrane is the rate of passive diffusion molecules across the biomembrane.
Answer:
Enzymes
Explanation:
The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.
During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.
