Biology MCQs

Notes:
Consumption of fish is considered to be healthy when compared to flesh of other animals because fish contains polyunsaturated fatty acids. Polyunsaturated fatty acid is an anti oxidant, which helps in building of tissues.

Notes:
Vitamin B1/Thiamine deficiency leads to a disease called beriberi. Over polishing of rice also leads to beriberi.

Notes:
Soma is also known as the God of plants or the king of gods or the special god of the Brahmanas. All the hymns of the eleventh mandal are assigned to him. Aryans considered Himalaya as the source of the soma plant.

Notes:
Insulin was the first peptide hormone discovered. Canadians Frederick Banting and Charles Herbert Best were the first scientists successfully isolated insulin from the dog pancreas in 1921. They achieved this tremendous feat while working in Canada’s University of Toronto J.J.R. Macleod Laboratory.

Notes:
Louis Pasteur was a French biologist, microbiologist, and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever and created the first vaccines for rabies and anthrax. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the “father of microbiology”.

Notes:
Lactobacillus bucheri is a naturally occurring, lactic acid bacteria that has a crucial role in forage preservation. It’s associated with indirect silage fermentation, which results in the production of acetic acid that inhibits yeast, prevents heating, and extends the bunk life of silage. Other species like Lactobacillus cacao num and Lactobacillus casei do not exhibit this function and Monosodium Glutamate is a flavor enhancer, not a preservative.

Notes:
Basidiomycota is one of the two larger divisions. Together with the Ascomycota, they constitute the subfamily Dicarya within the kingdom Fungi.

Notes:
Pollination is the process in which pollen grains are transferred from anther to Stigma.

Notes:
Sclerenchyma provides strength to the plant. It is found in the covering of seeds and nuts, around the vascular tissues in stems and the veins of leaves.

Notes:
Angiosperms show double fertilization. Angiosperms are plants that produce flowers and bear their seeds in fruits.
