Cholera is a disease due to consumption of contaminated food or water.
Cholera is caused by the bacterium Vibrio cholerae, which is transmitted through the fecal-oral route.
Ingestion of water or food contaminated with the feces of an infected person is the primary mode of transmission. The bacterium produces a toxin that causes severe watery diarrhea, leading to rapid dehydration. It is not a genetic disease, nor primarily related to alcohol consumption or causing loss of memory.

Lysosomes are the organelles of mammalian cells that are rich in hydrolytic enzymes.
Lysosomes contain enzymes like proteases, lipases, nucleases, and glycosidases, which work optimally in an acidic environment (pH ~4.5-5.0).
These enzymes are responsible for breaking down waste materials, cellular debris, excess organelles, and ingested pathogens through processes like phagocytosis and autophagy. Mitochondria are involved in energy production, ribosomes in protein synthesis, and the nucleus contains genetic material.

Penicillin resistant bacteria can degrade this antibiotic by an enzyme called β-lactamase.
Beta-lactamase enzymes break the beta-lactam ring structure, which is essential for the activity of penicillin and related antibiotics.
Bacterial resistance to antibiotics, including penicillin, is a significant public health challenge. Different bacteria have evolved various mechanisms to resist antibiotics, with beta-lactamase production being one of the most common for resistance to penicillin.

Electrocardiogram (ECG) is a graphical representation of the electrical activity of the heart.
An ECG machine records the electrical signals generated by the heart as it beats.
ECGs are used to diagnose various heart conditions, such as arrhythmias, myocardial infarction (heart attack), and heart failure by analyzing the patterns of electrical waves. It does not measure activity of the cornea, kidney, or brain (which is typically measured by EEG).

The correct way of writing a biological name as per the code of nomenclature is ‘Amoeba proteus’.
In binomial nomenclature, the genus name starts with a capital letter, and the species name starts with a small letter. Both names are typically italicized or underlined.
This system of nomenclature was largely developed by Carl Linnaeus. It provides a unique and internationally recognized name for each species. When handwritten, the genus and species names are usually underlined separately; when printed, they are typically italicized.
