Previous Years Based SSC GK (General Knowledge) MCQs
[B] The sperm fertilises the ovum
[C] The embryo is partially developed
[D] The end of gestation period is near
Biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY).Thus usually occurs as soon as conception takes place.
[B] It reacts with the metal of the container
[C] it reacts with the gases of the air
[D] None of the above
Camphor turns into its gas form and is thus no longer visible to the eyes. Camphor is sublime, it turns into gaseous state without turning into liquid state.
Insulin is a hormone made by an organ located behind the stomach called the pancreas. It allows body to use sugar from carbohydrates in the food. Insulin helps keep blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).
[B] Because gravitational pull is more at the poles
[C] Because gravitational pull is less at the poles
[D] None of the above
If we see the shape of the Earth, it is flatter at the poles and bulged at the equator. Therefore, the distance of the poles from the centre of the Earth is less than distance of the equator from the centre of the Earth. Now, recall the formula of gravitational force between two objects —F = (G * M1 * M2)/R^2. Here, R is the distance between the two objects. Distance is inversely proportional to the Force. Since the distance at the equator is more, it will have less gravitational force. Lesser the gravitational force, lesser will be the weight of the object. Since the distance between the poles is less, there will be more gravitational force. More is the gravitational force, more will be the weight of the object. Hence, the object will weigh minimum at the equator and maximum at the poles.
[C] Bacteria and Viruses respectively
[D] Viruses and Bacteria respectively
Causes range from bacteria, viruses, and parasites to food reactions and unclean water. The flu comes with symptoms like fever, congestion, muscle aches, and fatigue. The cause is the influenza virus. More severe cases can lead to life-threatening illnesses like pneumonia.
Individuals with type O Rh D negative blood are often called universal donors. This lack of antigens means that type O negative blood can be transfused in people of any blood type; hence, the term universal blood donor. Individuals with the blood group O Rh negative are called “universal donors” because their red blood cells can be transfused to people of all blood groups.
Acids are common in daily life. They are found within cells and digestive systems, occur naturally in foods, and are used for many common chemical reactions. Acids are molecular compounds that release hydrogen ions. A binary acid consists of hydrogen and one other element. Oxoacids contain hydrogen, oxygen, and one other element.
[B] Both salinity and density of sea decrease with depth
[C] Salinity increases but density of sea decreases with depth
[D] Salinity decreases but density of sea increases with depth
Salinity increases slightly with increasing depth. The density of sea increases with depth. The water molecules pack together tighter as pressure increases -the pressure increase with depth, due to the weight of the water above, and causes the greatest density changes in seawater with depth.
[B] Because they are not easily adjustable to new climate
[C] Because insects carried through fruits are dangerous
[D] All of the above
When fruits are imported from any other country they can carry insects and many other dangerous disease along with them .The only solution is to stop importing fruits and use the domestic fruits.
[B] Due to excessive intake of water
[C] Due to regular intake of foods
[D] Due to the constant flow of blood in the capillaries
The hypothalamus part of the brain works with other parts of the body’s temperature-regulating system, such as the skin, sweat glands and blood vessels. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
