- A pregnant mother supplies nourishment to her foetus through the placenta.
- Larvae of Hemichordata metamorphose into an adult after settling down at the bottom of the sea.
- Streptomycin is a powerful antibiotic against tuberculosis.
- Global problems arise during disaster.
Biology Questions
Progesterone, Estrogen, Testosterone, Insulin
- The odd man is Insulin, as the other three are hormones, while Insulin is a hormone and a protein.
Fragmentation, Transverse Binary Fission, Euglena, Sycon, Plenaria
- Fragmentation: Plenaria
- Transverse Binary Fission: Euglena
Biology and Health
- Aschelminthes have an aceolomate and bilaterally symmetrical body. (True)
Haemophilia, Factor VIII, Dwarfness
- Haemophilia : Factor VIII : : Dwarfness : Human Growth Hormone
Cybercrime
- Cybercrime refers to criminal activities carried out using the internet or other forms of computer technology.
Kreb's Cycle, Citric Acid Cycle
- Kreb's cycle is also known as the citric acid cycle because citric acid is the first compound formed in the cycle.
Microbial Enzymes, Chemical Industry
- Microbial enzymes are used instead of chemical catalysts in the chemical industry because they are more efficient, specific, and environmentally friendly.
Nuclear Power Plants
- It is absolutely necessary to control the fission reaction in nuclear power plants to prevent accidents and maintain safety.
Transcription, Translation
- Transcription is the process of creating a complementary RNA copy from a DNA template, while Translation is the process of building a polypeptide chain from mRNA.
Microorganisms, Oil Spills, Nocardia, PET
- Microorganisms are used to clear oil spills.
- Nocardia is used to convert salts of uranium into insoluble salts.
- Microorganisms are used to decompose PET.
Echinodermata, Phylum
- Distinguishing characters of phylum Echinodermata: radial symmetry, water vascular system, and unique body shape.
Type, Character, Example
- Cyclostomata: Having a notochord, dorsal hollow nerve cord, and pharyngeal slits.
- Gill respiration: Fish
- Amphibia: Frogs
- Whale: Mammal
- Poikilotherms: Fish
- Body is spindle-shaped: Lancelet ...
Menstrual Cycle, Reproductive Organs
- Reproductive organs that undergo changes in the menstrual cycle are the uterus and ovaries.
- The period of regeneration of endometrium is the proliferative phase.
- The period of secretions of glands in endometrium is the luteal phase.
mRNA, tRNA, rRNA, Amino Acids
- Each mRNA is made up of thousands of nucleotides.
- tRNA has an anticodon having a complementary sequence to the codon on mRNA.
- The process is called complementary base pairing.
- Amino acids are bonded together by peptide bonds with the help of rRNA.
- The ribosome keeps on moving from one end of mRNA to the other end by the distance of one triplet codon, which is called translocation.
Disasters, Cybercrime
- Types of Disasters: natural, man-made, and biological.
- Cybercrime refers to criminal activities carried out using the internet or other forms of computer technology.
Phylum, Sub-Kingdom
- The animals belonging to Phylum Porifera belong to sub-kingdom Parazoa.
- They bear numerous pores on their body called ostia and osculum.
- They have special type of cells called choanocytes.
- Their body is supported by a skeleton made up of calcium carbonate.
Complex Permanent Tissues, Animal Tissue
- Types of complex permanent tissues in plants: xylem and phloem.
- Two main types of animal tissue: epithelial and connective tissue.
- The most commonly used variety of worm used in sericulture is the silkworm.
- One method used in animal husbandry is artificial insemination.
Forensic Sciences
- The technique 'X' is DNA fingerprinting, which is mainly useful in forensic sciences.
- DNA fingerprinting is the process of identifying an individual by their unique DNA pattern.
- Use of DNA fingerprinting: solving crimes, identifying human remains, and determining paternity.
- Research on DNA fingerprinting is performed in forensic laboratories.
Thermal Power Plant
- Energy conversion in a Thermal Power Plant: chemical energy from coal -> heat energy -> mechanical energy -> electrical energy.
