About this paper
Part 13 (Q601–650) of the Sir Adnan '1000 Advanced Booklet Everyday Science' one-liner compilation (monster-data 'CSS MPT PAST PAPERS' pack). The booklet prints statement + answer only, so each item is published in the standard MCQ format with 3 authored plausible distractors under Anas's 2026-10-28 single-format decision and optionsSource recorded as 'authored'. Only 34 of 50 printed items are published. 16 restate facts already published in earlier parts of the same booklet and are cross-linked, not re-extracted: Q601 study of fossils (Q21 in Q1-50 / Q302 in Q301-350); Q604 vitamin K for blood clotting (Q225 in Q201-250); Q610 blood cleaned by kidney (Q288 in Q251-300); Q612 largest gland, liver (Q245 in Q201-250); Q613 hardest substance, tooth enamel (Q270 in Q251-300); Q617 heaviest naturally occurring element, uranium (Q106 in Q101-150); Q621 organ purifying blood, kidney (Q288 in Q251-300); Q622 vitamin C deficiency, scurvy (Q229 in Q201-250); Q629 universal donor, O Negative (Q217 in Q201-250); Q632 brain part controlling balance, cerebellum (Q259 in Q251-300); Q636 vitamin D deficiency, rickets (Q230 in Q201-250); Q638 organ producing insulin, pancreas (Q248 in Q201-250); Q640 normal body temperature, 98.6°F (Q219 in Q201-250, published as 37°C (98.6°F)); Q641 part storing bile, gallbladder (Q285 in Q251-300); Q643 element liquid at room temperature, mercury (Q104 in Q101-150, published as the metal liquid at room temperature); Q649 vitamin known as ascorbic acid, vitamin C (Q235 in Q201-250). No printed item in this stretch is dropped as unanswerable.

5 solved MCQs shown directly below
Correct Answer: Cytology
The branch of biology dealing with cells is called cytology: it studies the structure, function and behaviour of cells, the basic units of life.
Correct Answer: Gregor Mendel
Gregor Mendel is known as the father of genetics for his pea-plant experiments in the 1860s, which established the laws of inheritance.
Correct Answer: Cell
The cell is the smallest unit of life: it is the smallest structure that can carry out all the processes of life on its own.
Correct Answer: Deoxyribonucleic Acid
DNA stands for deoxyribonucleic acid: the molecule that carries the genetic instructions for the development, functioning and reproduction of organisms.
Correct Answer: Peregrine Falcon
The peregrine falcon is the fastest bird in the world, reaching over 320 km/h in its hunting dive (stoop).
Topic Section
4 solved MCQs shown directly below
Correct Answer: Oxygen
Oxygen is the most abundant element in the Earth's crust, making up about 46-47% of its mass, followed by silicon; aluminium is the most abundant metal, a different fact.
Correct Answer: Pacific Ocean
The Pacific Ocean is the largest ocean in the world, covering more surface area than all of Earth's land combined.
Correct Answer: Seismology
The study of earthquakes is called seismology: it covers the causes, measurement and effects of seismic waves.
Correct Answer: Hydrological Cycle
The process of the water cycle in nature is known as the hydrological cycle: water evaporates, condenses, precipitates and collects in a continuous loop.
Topic Section
6 solved MCQs shown directly below
Correct Answer: Carbon dioxide
Carbon dioxide turns lime water milky because it reacts with calcium hydroxide in lime water to form insoluble white calcium carbonate.
Correct Answer: Carbon dioxide
Carbon dioxide is used in the preparation of soda water: it is dissolved in water under pressure to make carbonated water.
Correct Answer: Sodium Chloride
The chemical name of table salt is sodium chloride, NaCl: a compound of one sodium atom and one chlorine atom.
Correct Answer: Hydrogen
Hydrogen is the lightest gas: with the smallest atomic mass of any element, it is lighter than helium, the next lightest gas.
Correct Answer: Nitrous Oxide
Nitrous oxide is known as laughing gas because inhaling it can produce euphoria and laughter; it is also used as an anaesthetic.
Correct Answer: H₂O
The chemical formula of water is H₂O: each molecule contains two hydrogen atoms and one oxygen atom.
Topic Section
5 solved MCQs shown directly below
Correct Answer: Ampere
The SI unit of electric current is the ampere: one ampere is one coulomb of charge passing a point per second.
Correct Answer: 32°F
The freezing point of water in Fahrenheit is 32°F, the temperature at which water turns to ice at standard atmospheric pressure.
Correct Answer: 100°C
The boiling point of water in Celsius is 100°C at standard atmospheric pressure (sea level).
Correct Answer: Newton
The SI unit of force is the newton: one newton is the force needed to accelerate a mass of one kilogram by one metre per second squared.
Correct Answer: Distance
The light year is a unit of distance: the distance light travels in one year in a vacuum, about 9.46 trillion kilometres.
Topic Section
6 solved MCQs shown directly below
Correct Answer: Venus
Venus is the planet nearest to Earth: its orbit lies closest to Earth's orbit and it makes the closest approaches to Earth of any planet.
Correct Answer: Galileo Galilei
Galileo Galilei is the conventional exam answer for the inventor of the telescope: he built his own improved refracting telescope in 1609 and used it for astronomy.
Correct Answer: Jupiter
Jupiter is the fastest rotating planet: it completes one rotation in about 9 hours 55 minutes, faster than any other planet in the solar system.
Correct Answer: Star
The sun is a type of star: a G-type main-sequence star whose nuclear fusion supplies light and heat to the solar system.
Correct Answer: Astronomy
Astronomy is the branch of science dealing with space: it studies celestial objects, space and the physical universe as a whole.
Correct Answer: Venus
Venus is known as the morning star because it is the brightest planet in the sky and is often visible near sunrise (and, as the evening star, near sunset).
Topic Section
2 solved MCQs shown directly below
Correct Answer: Malaria
Malaria is caused by Plasmodium parasites, transmitted to humans through the bites of infected female Anopheles mosquitoes.
Correct Answer: Goiter
Goiter is caused by deficiency of iodine: without enough iodine the thyroid gland enlarges as it struggles to make thyroid hormones.
Topic Section
1 solved MCQs shown directly below
Correct Answer: Vitamin D
Vitamin D is produced in the skin by sunlight: ultraviolet light converts a cholesterol compound in the skin into vitamin D3.
Topic Section
2 solved MCQs shown directly below
Correct Answer: Barometer
A barometer measures atmospheric pressure: a mercury or aneroid barometer shows the weight of the air column above it.
Correct Answer: Thermometer
A thermometer is used to measure temperature: it shows how hot or cold a body or substance is, in Celsius, Fahrenheit or Kelvin.
Topic Section
3 solved MCQs shown directly below
Correct Answer: Carbon dioxide
Carbon dioxide is the gas essential for photosynthesis: plants take it in from the air and, using sunlight, convert it with water into sugars and oxygen.
Correct Answer: Leaf
The leaf is the part of the plant that carries out photosynthesis: its chlorophyll-containing cells capture sunlight to make food.
Correct Answer: Chlorophyll
Chlorophyll is the green pigment in plants: it absorbs sunlight for photosynthesis and gives leaves their green colour.
Source & verification
Built by GK360 from verified bank questions — every answer rechecked before publishing. Where the source printed no options, the answer options were prepared by GK360; the questions and correct answers are the verified originals.
Questions
No. This is a practice set built from the Sir Adnan '1000 Advanced Booklet Everyday Science' one-liner compilation. It is labelled practice in the title, slug and paperType and must not be quoted as an official past paper.
This stretch of the booklet largely restates its own earlier parts: 16 of the 50 items repeat facts already published in Q1–600 of the same booklet (fossils, vitamin K and clotting, kidney purification, largest gland, tooth enamel, uranium, scurvy, universal donor blood group, cerebellum and balance, rickets, insulin, body temperature, bile storage, mercury at room temperature, and ascorbic acid). Those facts are cross-linked to their earlier publication, not re-extracted.
The booklet prints a statement and its answer only, with no options. Each item is published in the standard 4-option MCQ format with 3 authored plausible distractors, under the 2026-10-28 single-format decision; the answers themselves are the booklet's verified standard answers.
Venus is the conventional exam answer: its orbit lies closest to Earth's orbit and it makes the closest approaches to Earth. Time-averaged distance studies, which account for orbital positions over time, put Mercury closest on average — that nuance is flagged on the Venus item itself.
