Sample Question 1
Biology Easy • General Knowledge
The drugs caffeine, tannin and nicotine are:
A Steroids
B Cortisones
C Alkaloids
D Mild alkalis
โœ“ Correct Answer: C - Alkaloids
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Alkaloids are a group of naturally occurring organic compounds that contain mostly basic nitrogen atoms and have physiological effects on humans.
Sample Question 2
Biology Easy • General Knowledge
The type of crop which is able to fix nitrogen from air is known as:
A Tuber
B Coffee
C Legume
D Wheat
โœ“ Correct Answer: C - Legume
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Legumes (like peas and beans) have a symbiotic relationship with Rhizobium bacteria in their root nodules that convert atmospheric nitrogen into a usable form.
Sample Question 3
Biology Easy • General Knowledge
The saliva helps in the digestion of:
A Starch
B Proteins
C Fibres
D Fats
โœ“ Correct Answer: A - Starch
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Saliva contains the enzyme amylase (ptyalin), which begins the chemical breakdown of complex starches into simpler sugars like maltose.
Sample Question 4
Biology Easy • General Knowledge
Amniocentesis is a method for:
A Determination of foetal sex
B Separation of amino acids
C Determination of the sequence of amino acids in a protein
D Inducing abortion
โœ“ Correct Answer: A - Determination of foetal sex
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
While used to detect genetic abnormalities, amniocentesis allows for the analysis of foetal chromosomes, which reveals the sex of the child.
Sample Question 5
Biology Easy • General Knowledge
A recently developed technique for monitoring foetal growth uses:
A X-rays
B Microwaves
C Ultrasonic
D Ultraviolet rays
โœ“ Correct Answer: C - Ultrasonic
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Medical ultrasonography uses high-frequency sound waves to create images of the foetus, as it is non-ionizing and safe for prenatal care.
Sample Question 6
Biology Easy • General Knowledge
If there were no organic life on the Earth, the amount of oxygen in the atmosphere will:
A Remain unchanged
B Be approximately hundred per cent
C Be almost nil
D Be approximately fifty per cent
โœ“ Correct Answer: C - Be almost nil
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Nearly all atmospheric oxygen is a byproduct of photosynthesis performed by living organisms over billions of years.
Sample Question 7
Biology Easy • General Knowledge
Which of the following is not an element of the bone?
A Calcium
B Phosphorus
C Carbon
D Oxygen
โœ“ Correct Answer: C - Carbon
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Note: While bone contains organic carbon, the key (c) identifies it as the "non-mineral" element compared to the primary inorganic constituents.
Sample Question 8
Biology Easy • General Knowledge
Inspection and dissection of a body after death... is called:
A Autopsy
B Autotomy
C Autoesism
D Autograft
โœ“ Correct Answer: A - Autopsy
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
An autopsy is a highly specialized surgical procedure that consists of a thorough examination of a corpse to determine the cause of death.
Sample Question 9
Biology Easy • General Knowledge
The bulkiest muscle in the human body is found in:
A Legs
B Hands
C Hip
D Neck
โœ“ Correct Answer: C - Hip
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
The gluteus maximus, located in the hip/buttocks, is the largest and heaviest muscle in the human body.
Sample Question 10
Biology Easy • General Knowledge
Which of the following trees grows the fastest?
A Coconut
B Palm
C Mango
D Bamboo
โœ“ Correct Answer: D - Bamboo
๐Ÿ“– Step-by-Step Solution & Conceptual Rationale:
Some species of bamboo are the fastest-growing plants on Earth, with growth rates of up to 91 cm (36 in) in a 24-hour period.
