Comprehensive Electronic Assessment II

Comprehensive Digital Assessment (20 questions across 4 rounds) - Unit 2: The Body as a System & Thermal Energy

Milestone 1 of 4 Round 1: Launch Questions (1 - 5)

Question 1 of 20 1 Mark

Which of the following represents the correct sequence of hierarchical biological organization in multicellular living organisms?

Organism -> Tissue -> Cell -> Organ -> Organ System

Cell -> Organ -> Tissue -> Organ System -> Organism

Cell -> Tissue -> Organ -> Organ System -> Living Organism

Tissue -> Cell -> Organ System -> Organ -> Organism

Question 2 of 20 1 Mark

During the fight-or-flight emergency response, which hormone causes arterial heart rate and blood pressure to surge rapidly?

Thyroxine

Glucagon

Insulin

Adrenaline

Question 3 of 20 1 Mark

Which specialized connective tissue anchors a contracting skeletal muscle firmly onto a corresponding bone?

Nephron

Ligament

Cartilage

Tendon

Question 4 of 20 1 Mark

Why must skeletal muscles always operate in opposing antagonistic pairs across movable joints?

Because muscle fibers can only contract and pull; they have no active mechanism to push bones

Because bones are completely flexible and bend without mechanical support

Because joints can only move when both muscles relax simultaneously

Because tendons dissolve automatically whenever an arm is bent

Question 5 of 20 1 Mark

Which of the following organs contains involuntary smooth muscle tissue operating automatically beneath conscious awareness?

The biceps brachii muscle of the arm

The quadriceps muscle of the thigh

The voluntary neck muscles that turn the head

The muscular wall of the stomach and intestine

Question 6 of 20 1 Mark

Which blood vessels have microscopic, single-cell-thick walls that facilitate the rapid diffusion of oxygen, glucose, and metabolic wastes?

Lymphatic ducts

Capillaries

Veins

Arteries

Question 7 of 20 1 Mark

What is the primary hemodynamic purpose of one-way semilunar valves located inside systemic veins?

To filter nitrogenous urea directly into urine

To manufacture red blood cells from bone marrow

To pump arterial blood at high pressure into the brain

To prevent low-pressure venous blood from flowing backward under gravity

Question 8 of 20 1 Mark

Which endocrine hormone is secreted by the pancreas to stimulate cells to take in glucose from blood following a meal?

Insulin

Adrenaline

Thyroxine

Glucagon

Question 9 of 20 1 Mark

What is the primary clinical characteristic of Diabetes Mellitus?

Persistent high blood glucose concentrations due to deficient or ineffective insulin

Deficient production of hydrochloric acid in stomach pits

Total inability of the lungs to exhale carbon dioxide gas

Sudden destruction of all bones and ligaments in the arms

Question 10 of 20 1 Mark

What microscopic structure within the human kidney filters blood plasma, reclaims essential nutrients, and produces urine?

Neuron

Nephron

Villus

Alveolus

Question 11 of 20 1 Mark

Which toxic nitrogenous compound is synthesized by the liver from broken-down amino acids and subsequently excreted by the kidneys?

Glycogen

Glucose

Urea

Starch

Question 12 of 20 1 Mark

Why do large plasma proteins and blood cells remain inside glomerular capillaries rather than filtering into the nephron?

Because blood cells are repelled by magnetic forces in the cortex

Because their physical sizes are too large to pass through the filtration pores of the capillary walls

Because blood cells never enter the renal circulation

Because the kidney dissolves blood cells into carbon dioxide gas

Question 13 of 20 1 Mark

Which organ eliminates volatile carbon dioxide and water vapor produced during cellular respiration?

Stomach

Urinary bladder

Lungs

Kidneys

Question 14 of 20 1 Mark

Which of the following muscular anatomical conduits conveys urine downward from the kidney to the urinary bladder?

Ureter

Urethra

Trachea

Aorta

Question 15 of 20 1 Mark

What physical mechanism of heat transfer occurs within solid materials via direct particle vibration and kinetic collisions?

Convection

Sublimation

Conduction

Radiation

Question 16 of 20 1 Mark

Why does heated air rise above a domestic room heater while cooler air sinks toward the floor?

Gravity acts only on warm molecules and repels them into space

Warm air solidifies instantly and clings to ceiling tiles

Cold air is completely weightless and is repelled by the floor

Heated air expands, becomes less dense, and is buoyed upward by denser, cooler air

Question 17 of 20 1 Mark

Which mode of thermal energy transfer propagates via electromagnetic infrared waves and requires no material medium to travel?

Convection

Radiation

Conduction

Evaporation

Question 18 of 20 1 Mark

Which of the following materials is an excellent thermal conductor used to manufacture cooking pots for rapid heat distribution?

Aluminum or copper

Glass wool

Bakelite plastic

Dense wood

Question 19 of 20 1 Mark

What thermodynamic state occurs when two interacting physical bodies in thermal contact achieve equal temperatures?

Electrolytic saturation

Latent boiling transition

Absolute zero pressure

Thermal equilibrium

Question 20 of 20 1 Mark

How does the vacuum chamber in a double-walled thermos flask halt thermal energy transmission?

By eliminating material particles necessary for both conduction and convection

By generating positive magnetic fields that repel heat

By turning infrared radiation into cold visible light

By solidifying liquid contents into ice crystals instantly
