Biology Miscellaneous (Part-IV)

41. Development of the natural systems is described as: [53rd to 55th B.P.S.C. (Pre) 2011]

(a) Function of the systems
(b) Evolution of the systems
(c) Self-sustained process of the systems
(d) None of the above

Correct Answer: (c) Self-sustained process of the systems

Solution:The natural system regulates natural functions. So, the development of the natural system is defined as a self-sustained process of the system. Natural Systems" primarily involves studying ecosystems, their structure, functions, and the impact of human activities on them. This includes understanding the different types of ecosystems (terrestrial and aquatic), biotic and abiotic factors, and the interconnectedness within these systems. Ecosystems are characterized by the interactions between organisms and their physical environment, including energy flow, nutrient cycling, and trophic levels. Ecosystems perform vital functions like maintaining biodiversity, providing resources, and regulating climate and water cycles.

42. Scientists of the Chandra Shekhar Azad University of Agricultural and Technology have developed a substance that can reduce the percentage of flower droppings in pulses so as to enhance pulse production. Which is that substance? [U.P.P.C.S. (Mains) 2007]

(a) An insecticide called TIVA
(b) A fertilizer called TIVA
(c) A nutrient mixture called TIVA
(d) A growth hormone called TIVA
(e) An Intravenous Anaesthesia called TIVA

Correct Answer: (e) An Intravenous Anaesthesia called TIVA

Solution:TIVA is short for total intravenous anaesthesia. It is a technique of general anaesthesia using a combination of agents given solely by the intravenous route and in the absence of all inhalational agents, including nitrous oxide.

43. The true justified belief is often called: [M.P. P.C.S. (Pre) 2021]

(a) Hypothesis
(b) Intelligence
(c) Knowledge
(d) None of the above

Correct Answer: (c) Knowledge

Solution:

The true justified belief is often called knowledge. There are three components to the traditional ('tripartite') analysis of knowledge. According to this analysis, justified true belief is necessary and sufficient for knowledge. The tripartite analysis of knowledge is often abbreviated as the 'JTB' analysis, for 'justified true belief'. Much of the twentieth-century literature on the analysis of knowledge took the JTB analysis as its starting point.

44. Knowledge that we gain from school is called: [U.P. P.C.S. (Mains) 2017]

(a) Procedural memory
(b) Semantic memory
(c) Declarative memory
(d) Episodic memory

Correct Answer: (b) Semantic memory

Solution:

Semantic memory contains all of the general knowledge about our world that we have accumulated throughout our lives. General knowledge such as facts, ideas, meanings, and concepts related to our world are stored in semantic memory. It is a subset of long-term memory. So, the knowledge we gain from school is included in semantic memory.

45. Mental activity that goes on in the brain when a person is processing information is called: [U.P. P.C.S. (Mains) 2017]

(a) Mentation
(b) A concept
(c) Thinking
(d) Mental imagery

Correct Answer: (c) Thinking

Solution:Mental activity that goes on in the brain when a person is organizing and attempting to understand information and communicating information to others is called thinking. Thinking exists as the top mental activity demonstrated by man. All human accomplishments and advancements come as the result of thought. Civilization, knowledge, science, and technology arise from the thinking process; thought and thinking are inseparable.
