Acute inferior myocardial infarction. Documented mildly occlusive plaque with much clot in the right coronary artery
<h3>
What is myocardial infarction?</h3>
- A myocardial infarction (MI), also referred to as a heart attack, happens when blood flow to the heart's coronary artery is reduced or interrupted, harming the heart muscle.
- The most typical symptom is discomfort or soreness in the chest, which may radiate to the shoulder, arm, back, neck, or jaw. It frequently lasts more than a few minutes and usually happens in the center or left side of the chest.
- Sometimes the discomfort may feel like heartburn. Other signs and symptoms could include fatigue, shortness of breath, nausea, feeling dizzy, and cold sweats.
- Atypical symptoms are present in about 30% of patients. Women more frequently experience arm, neck, or fatigue discomfort instead of chest pain.

Answer:
polyphyletic
Explanation:
Polyphyletic
The organisms in this groups show similar attributes, but lack a recent common ancestor and could have risen from convergence.
Take for instance, birds and mammals in a polyphyletic group of warm-blooded animals may possess a mixture of biochemical and physiological attributes. On the other hand, their most recent common ancestor was a cold-blooded species, which shows birds and mammals had their warm-blooded nature as separate groups.
Another example is the Elephants, hippopotamuses, and rhinoceroses belongs to a polyphyletic groups with each one coming from a separate small species.

Explanation:
RNAi is a cellular mechanism for post-transcriptional gene silencing. After transcription of a gene into mRNA, small interfering RNA (siRNA) and microRNA (miRNA) can target the mRNA to form dsRNA. This mRNA then becomes a target of ribonucleases such as the Dicer that break it apart. These mRNA, therefore, do not reach the cytoplasm for translation by ribosomes. This mechanism is hence harnessed and manipulated by scientists to study genes by silencing them.
An occluded front forms when two cold air masses meet and push warmer air up, making the temperature drop and usually bring strong rains and wind.
