Correct answer: A). Light slows down as it moves from the air in to the water, resulting in refraction, or a bending of light.
This is because as light travels through one media it travels in a straight line, however, when it travels from one media to another media it bends, light path bends because of the phenomenon of refraction of light.
The refraction takes place only at the boundary, as the light continues to cross the boundary, it travels in a straight line.
So, as the portion of the pencil is submerged in water, the light will travel from water to air.
Hence it appears to be broken because of refraction of light. So, the correct answer would be option A.

Answer:
36
Explanation:
A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
Answer:
Chloride concentration in urine is more who drank sport drink as compared to a person who drank normal water.
Explanation:
Chloride concentration in urine is high who drank sport drink as compared to a person who drank water because in sport drink there is more concentration of salts are present which is required our body. Due to more salts present in the sport drink, more chloride is present in urine due to the removal from the body while normal water has less amount of salts so urine has less concentration of chloride in urine.
