Introduction: Hey there, curious minds! Have you ever wondered how those amazing electronic devices work? Well, let’s dive into the fascinating world of semiconductors and explore the difference between P-type and N-type semiconductors. What are Semiconductors? Before we get into the nitty-gritty details, let’s understand what semiconductors are. Imagine a material that can conduct electricity, … Read more
Ans: (1) Thyroxine is the main metabolic hormone in the body. (2) Thyroxine maintains basal metabolic rate (BMR) by increasing glucose oxidation. It causes a calorigenic effect by producing energy. (3) It also controls normal protein synthesis. (4) The physical growth, development of gonads, and development of mental faculties is under the control of thyroxine. (5) … Read more
Ans: (1) A Test cross can be used to find out the genotype of any plant that shows dominant characteristics. (2) Whether the plant is homozygous or heterozygous can be understood by performing test cross. (3) Test cross is used to introduce useful recessive traits in the hybrids of self-pollinated plants. (4) Test cross is … Read more
Ans: The Hardy-Weinberg equilibrium law states that at the equilibrium point, both the allelic frequency and genotype frequency remain constant from generation to generation, in a diploid, sexually reproducing, large, population that freely interbreeds in which mating is random and where no additional influences exist to alter the allele frequency.
