Classify the chromosomes on the basis of position of Centromere. Write brief note on giant chromosomes. [Answer Limit: 50 words] [UKPSC 2023]
Chromosomes are divided underneath Metacentric, Submetacentric, Acrocentric and Telocentric on the premise of centromere position. So metacentric have centromeres in the middle, submetacentric are slightly off middle, acrocentric are near one stop, and telocentric on the end. In flies, that is due tRead more
Chromosomes are divided underneath Metacentric, Submetacentric, Acrocentric and Telocentric on the premise of centromere position. So metacentric have centromeres in the middle, submetacentric are slightly off middle, acrocentric are near one stop, and telocentric on the end. In flies, that is due to massive chromosomes (polytene chromosomes), the result of many rounds of DNA replication without the cellular dividing, which give a whole lot of genetic information.

The diseases of the honey-bee Identified by: 1) American Foulbrood which causes brown larvae, to “tell it like it is” to clear the “casket” and die. 2) European Foulbrood of the man with starving larvae, and twisted, off-white bodies 3) Nosema of the adult bee with a swollen abdomen, and dysentery eRead more
The diseases of the honey-bee Identified by:
1) American Foulbrood which causes brown larvae, to “tell it like it is” to clear the “casket” and die.
2) European Foulbrood of the man with starving larvae, and twisted, off-white bodies
3) Nosema of the adult bee with a swollen abdomen, and dysentery extruding from the posterior
4) Varroa Mite infestation, recognized by the deformed wings, and weakness of the bees. Each brings its own threats to hive health and productivity.
See lessWrite the differences between volatile memory and non-volatile memory. [Answer Limit: 50 words] [UKPSC 2023]
When power is applied, data is stored in RAM and accessed quickly, but is lost when power is removed, in which case volatile memory is used. Volatile memory (e.g., RAM) only temporarily stores data while powered on, while non-volatile memory (e.g. SSDs or HDDs) retains data even without power, albeiRead more

See lessGive an account of cultivable species of fishes in Uttarakhand. [Answer Limit: 50 words] [UKPSC 2023]
Uttarakhand is a biodiversity-dense region which has several fish species with the potential to be cultivated. Some of the major cultivable species include Indian major carps (Rohu, Catla, and Mrigal), common carp, trout. These fishes thrive in the state’s rivers, streams, and artifical reservoirs aRead more
Uttarakhand is a biodiversity-dense region which has several fish species with the potential to be cultivated. Some of the major cultivable species include Indian major carps (Rohu, Catla, and Mrigal), common carp, trout. These fishes thrive in the state’s rivers, streams, and artifical reservoirs and are a substantial contributor to local aquaculture and fisheries. Sustainable cultivation of such plants can ensure their roles and contribution towards the economy.
See lessWhy is blood group O-negative (O) considered as the universal donor? Give the reason for it. [Answer Limit: 50 words] [UKPSC 2023]
O-negative is the universal donor (because it has no A, B, or Rh antigens and therefore is like minded with all blood kinds). This uncommon belongings makes O-negative blood secure to transfuse to sufferers of any blood type, particularly in an emergency.

Bio-fertilizers are the ones produced from living microorganisms which improve soil fertility and stimulus to plant growth as natural way. These are differentiated into three characteristic i.e. bacterial (Rhizobium, Azotobacter), fungal (mycorrhizae), and algal (green-blue algae). They fix atmospheric nitrogen, solubilize phosphates and decompose organic matter, making nutrients more accessible to plants. Bio-fertilizers can hold a number of advantages, including better soil health, higher crop productivity, and decrease in reliance on fertilizers that can have an adverse affect on the surrounding habitat. They help foster sustainable agriculture because they enhance soil biodiversity and resilience. Bio-fertilizers are inexpensive and can be produced at a local level and becliboe is available to small-scale farmers.
