Answer:
Pericarditis,an infection with an accumulation of fluid in the pericardial sac,can lead to cardiac attack ,as the fluid compress the heart and stops from beating.
Explanation:
Pericarditis is mainly caused by viral infection in the respiratory tract.Pericarditis is an autoimmune disorder as they release antibody which attack body's own tissue and cells.
Pericarditis mainly affect people with age between 20-50
Pericarditis means inflammation in the pericardium region which is a sac like like structure and surrounds the heart.
The symptoms include Chest pain,Cardiac attack and some times cause death.
Pericarditis may be acute as it happens suddenly and does't lasts for longer time.
A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.
Explanation:
This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.
This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.
The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.

Answer:
The environments in which cells grow often change rapidly. For example, cells may consume all of a particular food source and must utilize others. To survive in a changing world, cells evolved mechanisms for adjusting their biochemistry in response to signals indicating environmental change. The adjustments can take many forms, including changes in the activities of preexisting enzyme molecules, changes in the rates of synthesis of new enzyme molecules, and changes in membrane-transport processes.
Initially, the detection of environmental signals occurred inside cells. Chemicals that could pass into cells, either by diffusion through the cell membrane or by the action of transport proteins, and could bind directly to proteins inside the cell and modulate their activities.
Answer:
Option C “the reason the data are collected”
Explanation:
The epidemiology studies based on four criteria for utility of data are
1-Nature of data
2-Availability of the data
3-Completeness of data and
4- value and limitation.
Value and limitation of data means that some factors may limit the data usefulness like incomplete information or repetition and duplicate data while Nature of data means the data source which affect the statistical analysis. Availability of data means the presence or access of data to investigators.
