Enzymes can be described as proteins which act as biological catalysts. Enzymes can speed up a reaction. During this process, the enzyme itself doesn't get consumed and hence, it can be reused. Enzymes are specific for a particular type of substrate and hence, they can catalyze only those reactions for which they are specific. Hence, option B is correct.
Other options like option A is not correct because the mass of an enzyme will not change after a reaction.
<span>The stage at which all the cells show crossover chromosomes is meiotic prophase I. The crossover is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I. Regarding the phase of meiosis I, it is expected that the crossover takes place in meiotic prophase I since homologous chromosomes pair up in the prophase.</span>
