Kwashiorkor is a severe form of malnutrition primarily caused by:
A. Calorie deficiency
B. Vitamin A deficiency
C. Protein deficiency
D. Iron deficiency
Answer: Option C
Solution (By JKExamLibrary)
Kwashiorkor is a severe form of malnutrition in children caused by a significant deficiency of protein in the diet, despite potentially adequate calorie intake. It is characterized by edema (swelling, especially in the belly due to low albumin), an enlarged liver, thinning hair, and a 'flaky paint' skin rash. Marasmus is caused by overall protein-calorie deficiency.
Explanation:
The Hardy-Weinberg equation is a fundamental principle in population genetics used to calculate the expected frequencies of genotypes in a population that is not evolving (in genetic equilibrium). 'p' represents the frequency of the dominant allele, and 'q' represents the frequency of the recessive allele. p^2 is the frequency of the homozygous dominant genotype, 2pq is the heterozygous genotype, and q^2 is the homozygous recessive genotype.
Explanation:
Erythropoietin (EPO), mainly from kidneys, promotes erythropoiesis in bone marrow. Thrombopoietin stimulates platelets, interleukins are immune cytokines, CSFs for white blood cells. EPO is used to treat anemia.
Explanation:
Cellular respiration breaks down glucose and other nutrients in the presence of oxygen to produce ATP. Photosynthesis builds glucose, fermentation is anaerobic energy production, transpiration is water loss.
