Answer: I would answer B just from looking at it because they are the two bigger objects and they're the closest together
Explanation:
Answer: Water as a universal solvent
Explanation:
Water is a universal solvent because of its property of dissolving a large number of molecules of different kind. The water at the biological level forms the major body weight of the organisms. It helps in supporting the cell metabolism and function. It is the main component of the liquid component of blood that is plasma. The water dissolved in it various vitamins, minerals, fibers, and other components of the food and helps in digestion of food in the body. Thus in human and animal body water plays an important role in circulation and digestion process.
Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
Answer:
The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).
