General Science Biology Questions
41. Maximum number of animals species belong to which among the following groups?
[A] Mammalia
[B] Aves
[C] Pisces
[D] Arthropoda
[D] Arthropoda
Notes:
Arthropoda is the largest phylum of animal kingdom because around 2/3rd of all the named species on Earth belong to this phylum.
Ants, mosquitoes, flies, cockroaches, shrimp, crabs, spiders, scorpions etc. are examples of arthropods. There are three main classes of arthropods as follows:
Insects: This includes mosquitoes, cockroaches, ants, flies, bees, moths, grasshoppers, beetles and butterflies
Crustaceans: This includes crabs, lobsters, shrimp and barnacles
Arachnids: This includes scorpions, spiders and mites
Further, a few other classes are onychophorans (velvet worms), diplopods (millipedes) and chilopods (centipedes).
42. “Minimata Disease ” is a severe neurological syndrome caused by eating fish and discovered in Japan. What was factor behind this disease?
[A] Arsenic Poisoning
[B] Mercury Poisoning
[C] Lead Poisoning
[D] Cadmium Poisoning
[B] Mercury Poisoning
Notes:
Minamata disease, sometimes referred to as Chisso-Minamata disease, is a neurological syndrome which is caused by severe mercury poisoning. Some of the symptoms of the disease are numbness in the hands and feet, ataxia, general muscle weakness, etc.
43. In which of the following diseases , nerve cells are affected?
[A] Tetanus
[B] Polio
[C] Whooping Cough
[D] Diphtheria
[B] Polio
Notes:
Nerve cells are affected in Polio. Polio also known as poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus spreads from person to person and can infect a person’s spinal cord, causing paralysis.
44. How many vertebrae does a human being have ?
[A] 33
[B] 36
[C] 29
[D] 19
[A] 33
Notes:
The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).
45. Which among the following enzyme plays an important role in adding the building blocks to the primer in a sequence determined by the DNA template?
[A] Helicase
[B] Primase
[C] Polymerase
[D] Diastase
[C] Polymerase
Notes:
Polymerase enzyme plays an important role in adding the building blocks to the primer in a sequence determined by the DNA template. It synthesizes long chains of polymers or nucleic acids.
46. Which among the following is not rightly matched : (Ailments and affected parts of Body)
[A] Dermatitis – Skin
[B] Glossitis – Tongue
[C] Peritonitis – Abdomen
[D] Cystitis – Caecum
[D] Cystitis – Caecum
Notes:
Cystitis is related to Bladder.
47. Which among the following is the correct location of pyloric sphincter in human body?
[A] Between Oral cavity and esophagus
[B] Between Esophagus and Stomach
[C] Between Stomach and duodenum
[D] Between duodenum and Jejunum
[C] Between Stomach and duodenum
Notes:
Pyloric sphincter is located between stomach and duodenum. It is a small piece of smooth visceral muscle, which acts as a valve and regulates the flow of partially digested food from the stomach to the duodenum.
48. Which among the following helps to determine the character of a cell?
[A] Nucleus
[B] Chromosomes
[C] Genes
[D] Plasma
[C] Genes
Notes:
Genes helps to determine the character of a cell. Gene is the basic physical and functional unit of heredity and are made up of DNA. Some of the genes act as instructions to make molecules called proteins.
49. As per the WHO definition, within how many days of the termination of pregnancy, the death of a woman is counted in the Maternal Mortality?
[A] 36 Days
[B] 42 Days
[C] 56 Days
[D] 60 Days
[B] 42 Days
Notes:
As per the WHO definition, within 42 days of the termination of pregnancy, the death of a woman is counted in the Maternal Mortality, irrespective of the duration and site of the pregnancy.
50. What is PRINT (Particle Replication in Non-wetting Templates) Technology ?
- [A] It’s a technology related to genetic engineering and refers to duplication of the DNA codes.
- [B] It’s a technology related to climate change and refers to a new technique of combating air pollution.
- [C] It’s a new technology related to synthesis of artificial blood.
- [D] None of the above.
[C] It’s a new technology related to synthesis of artificial blood.
Notes:
PRINT (Particle Replication in Non-wetting Templates) Technology is a new technology related to synthesis of artificial blood. PRINT method has been widely applied onto material sciences, drug delivery, electronic devices, optics, etc.
