General Science Questions (MCQs) for Competitive Examinations

Notes:
Capra Hircus is the scientific name of domestic goat or simply goat. It is a subspecies of C. aegagrus domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and is closely related to the sheep; both are placed in the goat-antelope subfamily Caprinae.

Notes:
Taenia (Tapeworm), Fasciola (Liver fluke) are examples of Platyhelminthes, mostly parasites that live in other animals including animals. Some are freeliving forms, mainly aquatic-marine or freshwater. Their bodies remain externally covered by cilia or cuticle.

Notes:
Cod liver oil is the oil extracted from the livers of Atlantic cod. It is commonly taken as a dietary supplement and is packed full of nutrients. It is one of the best sources of omega 3 fatty acids (EPA and DHA), and it contains relatively high amounts of vitamin A and vitamin D. It is a vital nutrient for immune system function, cellular growth, eye health, and reproduction. It decreases blood clot formation and reduce inflammation in the body.

Notes:
The National Viral Hepatitis Control Program aims to combat hepatitis and achieve country wide elimination of Hepatitis C by 2030. Launched on 28 July, 2018, it also aims to achieve significant reduction in the infected population, morbidity and mortality associated with Hepatitis B and C viz. Cirrhosis and Hepato-cellular carcinoma (liver cancer).

Notes:
A fern is any one of a group of about 20,000 species of plants classified in the phylum or division Pteridophyta, also known as Filicophyta. Fern ally is a general term covering a somewhat diverse group of vascular plants that are not flowering plants (angiosperms) and not true ferns. Like ferns, these plants reproduce by shedding spores to initiate an alternation of generations. Both Ferns and fern allies belong to Pteridophytes.

Notes:
Dermatitis, also known as?eczema, is a group of diseases that results ininflammationof the?skin. These diseases are characterized by?itchiness, red skin, and a rash. Itai-Itai is caused by cadmium poisoning and Minamata due to mercury poisoning.

Notes:
Chlorophyll, a photo-receptive pigment, allows plants to absorb sunlight. Chlorophyll is a chlorine pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorine ring is a magnesium ion. The molecular formula of C55H70O6N4 Mg. Hence, chlorophyll as a pigment lacks calcium.

Notes:
The term xerophyte refers to a plant species that has evolved over time to adapt to dry and arid regions like deserts. Xerophytes have adapted to be able to keep extremely large amounts of water for a long period of time. Without this capability, the plant would die, as the desert region itself does not provide enough water to sustain life. They have thick cuticle, sunken stomata and leaves modified in form of spines such as in opuntia.

Notes:
Vitamin K refers to a group of fat-soluble vitamins that play a role in blood clotting, bone metabolism, and regulating blood calcium levels. The body needs vitamin K to produce prothrombin, a protein and clotting factor that is important in blood clotting and bone metabolism.

Notes:
Adamsia (Sea anemone), Pennatula (Sea-pen) are examples of Anthozoa Class under Coelenterata Phylum. The organism under this phylum are mostly marine, solitary or colonial, sessile, or free-swimming and radially symmetrical animals. Other examples of Anthozoa class are Meandrina (brain-coral), Fungia, Gorgonia (sea fan or horny coral), etc.
