Biology and Web Security Basics Quiz

AIDS (caused by HIV), mumps, and poliomyelitis are all viral diseases. AIDS is caused by the Human Immunodeficiency Virus (HIV), mumps by the mumps virus, and polio by poliovirus. This distinguishes them from bacterial, fungal, or parasitic diseases. While option D has some truth for AIDS (blood transmission can spread HIV), it doesn't apply to mumps or polio, making option C the unifying characteristic.

The human heart beats approximately 72 times per minute at rest. Each beat involves the heart valves opening and closing once. Calculating: 72 beats/minute × 60 minutes/hour × 24 hours/day = 103,680 times, which rounds to approximately 100,000 times per day. This makes option B the correct answer.

Photosynthesis is the only process listed that purifies air rather than polluting it. During photosynthesis, plants absorb carbon dioxide and release oxygen, improving air quality. The other options - cosmetics (contain VOCs), burning dead wood (releases smoke and particulate matter), and insecticides (chemical pollutants) - all contribute to air pollution in various ways.

Pepsin is the enzyme in gastric juice that begins protein digestion by breaking down proteins into smaller polypeptides called peptones. It works optimally in the acidic environment of the stomach. Trypsin (from pancreas) further breaks down peptides, Erepsin (from intestinal juices) completes protein digestion by breaking peptides into amino acids, and Enterokinase activates trypsin.

The pituitary gland, often called the 'master gland,' is the smallest gland in the human body - approximately the size of a pea (about 0.5 grams) and located at the base of the brain. Despite its small size, it produces and regulates numerous hormones that control other endocrine glands and bodily functions. The liver is much larger, the thyroid is also small but larger than the pituitary, and salivary glands are visibly larger.

Ernest Rutherford is widely regarded as the father of nuclear physics for his groundbreaking work on radioactive decay and the structure of the atom. He discovered the alpha and beta radiation and proposed the nuclear model of the atom. Hans Geiger co-developed the Geiger counter but Rutherford was the pioneer.

Input validation against a whitelist is a correct injection prevention mechanism. A whitelist defines exactly what inputs are allowed, rejecting anything that doesn't match. This prevents injection attacks by ensuring only valid, expected data enters the system. Avoid escaping special characters would make you vulnerable, non-parameterized APIs are vulnerable, and while avoiding wrong data helps, validation against whitelist is the technical prevention mechanism.

Option C is the correct answer because 'Avoid sending the wrong data' is not a technical injection prevention mechanism - it's a general practice rather than a specific defensive technique. The other options ARE valid prevention mechanisms: escaping special characters (A), using parameterized APIs/prepared statements (B), and input validation with whitelists (D) are all standard techniques for preventing SQL injection and similar attacks.

The description 'text-based attack data that exploit the interpreter in the browser' is the textbook definition of Cross Site Scripting (XSS). In XSS attacks, malicious scripts are injected into web pages viewed by other users, exploiting the browser's script interpreter. This distinguishes it from Injection (server-side interpreter), CSRF (exploiting authenticated sessions), and URL access restrictions (authorization bypass).

Cross Site Scripting (XSS) specifically targets the browser's interpreter - it exploits how browsers interpret and execute scripts within web pages. Unlike attacks that target servers (B, C) or file systems (A), XSS payloads run in the victim's browser context. The term 'Browser Interpretation' (D) correctly identifies this client-side execution environment.
