Question 3

The essential ion required for muscle contraction, facilitating the interaction between actin and myosin filaments, is:

Accepted Answer

C. Calcium (Ca2+) — Calcium ions (Ca2+) play a pivotal role in muscle contraction. When released from the sarcoplasmic reticulum, Ca2+ binds to troponin, causing a conformational change that moves tropomyosin away from the actin binding sites, thereby allowing myosin heads to attach to actin and initiate the contraction cycle. Sodium and potassium ions are crucial for nerve impulse transmission and muscle action potentials, but not directly for the actin-myosin interaction itself.

Answer

A. Sodium (Na+)

Answer

B. Potassium (K+)

Answer

D. Chloride (Cl-)

Question 7

Dr. Sharma, a research scientist, is faced with a completely novel experimental challenge for which no standard protocols or established solutions exist. She spends considerable time brainstorming unconventional approaches, combining disparate ideas from different fields, and eventually devises an entirely new methodology that successfully addresses the problem. This capability primarily reflects which component of Robert Sternberg's Triarchic Theory of Intelligence?

Accepted Answer

B. Experiential (creative) intelligence. — Sternberg's experiential (creative) intelligence is characterized by the ability to deal with novelty and to automate information processing. Dr. Sharma's approach of brainstorming unconventional methods and combining disparate ideas to solve a novel problem perfectly illustrates the creative aspect of experiential intelligence, distinct from analytical problem-solving or adapting to an existing context.

Answer

A. Componential (analytical) intelligence.

Answer

C. Contextual (practical) intelligence.

Answer

D. Crystallized intelligence.
