GSA CSS 2024 ANSWERS
Sure, here are mcqs explanations for CSS General Science paper 2024 Section-A
- In fish liver oil, there is:
Answer: Vitamin A and Vitamin D
Explanation: Fish liver oil is rich in both vitamin A and vitamin D. Vitamin A is essential for maintaining healthy vision, skin, and immune function, while vitamin D is crucial for bone health, immune function, and overall well-being. These vitamins are often found together in foods like fish liver oil, making it a valuable dietary source for both nutrients. -
When day and night are equal?
Answer: 21 March and 23 September
Explanation: Equinoxes occur around March 21st and September 23rd each year. During an equinox, the length of day and night is approximately equal across the globe. This phenomenon happens because the plane of Earth’s equator passes the center of the Sun, causing the Sun to be positioned directly over the equator. -
What is the total number of combinations of 9 things taken 3 at a time?
Answer: 84
Explanation: The total number of combinations of n things taken r at a time is calculated using the combination formula: C(n, r) = n! / [r! * (n – r)!]. For this question, it’s C(9, 3) = 9! / [3! * (9 – 3)!] = 84. -
The chemical formula for alum is:
Answer: KAI(SO₄)₂ 12 H₂O
Explanation: Alum, a compound commonly used in various industrial and household applications, has the chemical formula KAI(SO₄)₂ 12 H₂O. It is a hydrated double sulfate salt containing aluminum. -
If the radius of a circle is increased three times, then its area is increased:
Answer: Nine times
Explanation: The area of a circle is proportional to the square of its radius. So if the radius is increased three times, the area will be increased by a factor of (3^2) = 9 times. -
One degree of longitude on the equator is equal to a distance of:
Answer: 69 miles
Explanation: At the equator, one degree of longitude corresponds to approximately 69 miles. This value varies slightly depending on the exact shape of the Earth. -
The protein molecule is made of:
Answer: Long-range chain of amino acids
Explanation: Proteins are large biomolecules made up of long chains of amino acids. These chains fold into complex three-dimensional structures, which determine the protein’s function. -
The minimum amount of vitamin stored in the human body is of:
Answer: Vitamin D
Explanation: Among the given options, vitamin D is the only vitamin that can be stored in the body. Excess vitamin D is stored in fat tissues and released when needed. -
The isotopes of any element contain an equal number of:
Answer: Protons
Explanation: Isotopes of an element have the same number of protons (which defines the element), but they differ in the number of neutrons, leading to variations in atomic mass. -
The pH of soil is raised using:
Answer: Lime stone
Explanation: Limestone (calcium carbonate) is commonly used to raise the pH of acidic soil. It acts as a buffer, neutralizing excess acidity and improving soil fertility. -
Which of the following is used for measuring distance?
Answer: Light year
Explanation: A light-year is a unit of length used in astronomy to measure vast distances in space. It represents the distance that light travels in one year in a vacuum, approximately 9.461 trillion kilometers. -
__________ is used as an anesthetic.
Answer: Chloroform
Explanation: Chloroform, a volatile liquid with anesthetic properties, was historically used as a general anesthetic in medical procedures. However, due to its toxic and carcinogenic effects, its use has been largely discontinued. -
A pencil dipped in water appears bent due to?
Answer: Refraction.
Explanation:
When a pencil is dipped in water, it appears bent due to refraction. Refraction is the bending of light as it passes from one medium to another of different optical density, such as from air to water. This bending of light causes the pencil to appear displaced or bent at the water’s surface.. -
Fishes die outside the water due to:
Answer: Oxygen
Explanation: The option that leads to the death of fishes outside water is “Non-absorption of oxygen”. When fishes are out of water, their gills can’t extract oxygen from the surrounding air efficiently. As a result, they can’t breathe properly, leading to a lack of oxygen in their bodies, which can cause their death. Therefore, the absence or non-absorption of oxygen is what ultimately leads to the death of fishes outside water.. -
In dementia, a person:
Answer: Loses thinking, remembering, and reasoning
Explanation: Dementia is a neurological disorder characterized by a decline in cognitive function, affecting thinking, memory, and reasoning abilities. -
Earthquake is measured by the instrument:
Answer: Seismograph
Explanation: A seismograph is an instrument used to measure the magnitude and duration of seismic waves generated by earthquakes. -
A cyclone is formed:
Answer: When warm, moist air rises upward over the ocean
Explanation: Cyclones, also known as hurricanes or typhoons, are formed when warm, moist air rises upward over the ocean’s surface, creating a low-pressure system that can develop into a storm. -
Why is red light used in a traffic signal for danger?
Answer: It has long wavelength and high frequency
Explanation: Red light has a relatively long wavelength and low frequency compared to other colors in the visible spectrum. It is used in traffic signals for danger because it is easily visible and grabs attention, especially during low light conditions. -
The heavy water is:
Answer: Denoted by D₂O and contains deuterium
Explanation: Heavy water, denoted by D₂O, is a form of water where the hydrogen atoms are replaced with deuterium, a heavy isotope of hydrogen containing one proton and one neutron. -
The ionosphere is located within the thermosphere and extends:
Answer: From 50-300 km above the Earth’s surface
Explanation: The ionosphere is a region within the Earth’s upper atmosphere, located within the thermosphere, and extends from approximately 50 to 300 kilometers above the Earth’s surface. It contains a high concentration of ions and free electrons, which play a crucial role in various atmospheric phenomena and radio wave propagation.
