Metastasis is when cancerous cells spread into or invade nearby tissues and can treat malignant tumors.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Metastasis is when cancerous cells spread into or invade nearby tissues and can travel to distant places in the body to form new tumors. This process involves the detachment of cancer cells from the primary tumor, their movement through the bloodstream or lymphatic system, and the establishment of new tumors in other parts of the body.

Choice B rationale

Metastasis specifically involves cancerous cells, not normal cells. Normal cells do not spread and invade other tissues in a way that causes new tumor formation.

Choice C rationale

Metastasis refers to the spread of cancerous cells, not normal cells. Normal cells do not exhibit the same invasive and migratory behaviors as cancerous cells.

Choice D rationale

Metastasis involves the spread of cancerous cells, which can lead to the formation of malignant tumors in distant parts of the body. It does not treat tumors but rather contributes to the progression of cancer.

Choice C rationale

Cyclobenzaprine is not indicated for spasticity related to cerebral palsy, spinal cord injury, or multiple sclerosis. Other medications like baclofen or dantrolene are used for these conditions.

A. Captopril. B. Losartan. C. Lisinopril. D. Metoprolol.

Correct Answer is ["A","C"]

Explanation

Choice A rationale

Captopril is an Angiotensin Converting Enzyme (ACE) Inhibitor, which works by inhibiting the conversion of angiotensin I to angiotensin II. This leads to vasodilation and reduced blood pressure, making it effective in treating hypertension.

Choice C rationale

Lisinopril is also an Angiotensin Converting Enzyme (ACE) Inhibitor. It lowers blood pressure by blocking the formation of angiotensin II, a powerful vasoconstrictor, and thereby reducing systemic vascular resistance and blood pressure.
