Answer: C. detect when an unattended language was changed to German.
The cocktail party effect refers to ability of a person to focus on a single speaker or conservation in a noise prone area. This mainly reflects listening ability of the person in a noisy environment. If a listener hears unattended language for a particular time along with noise.The listener may loose interest in listening and he will not show alertness when language changes to German which could be known language to listener.
In experiments testing the cocktail party effect, most participants were only able to detect when the speaker’s voice changed from male to female, illustrating the selective nature of our auditory perception.
The cocktail party effect is a psychological phenomenon where one can focus their auditory attention on a specific source while filtering out other background noises. This effect is named after a scenario of a cocktail party where one can focus on a single conversation in a noisy room. In experiments testing this effect, most participants were able to do one specific thing from the options given: that is, option A. detect when the speaker’s voice changed from male to female.
Participants found it hard to perform all the other tasks given. This is because the 'unattended' information in the auditory scene was not being processed to the point where the participants could identify phrases (option B), notice language changes (option C), or detect specific changes when the speech was played backward (option D). This highlights the selective nature of our auditory perception.

The correct answer is Mitosis.
The mitosis is a type of cell division, in which the parent cell produces a similar type of daughter cell. The daughter cells, which are formed by the process of the mitosis would have the same number of the chromosomes and the ploidy of the daughter cells would also be same as the parents. In the sexual reproduction, the process of meiosis result in the formation of haploid cells during the process of gamete formation. Hence, meiosis, sexual reproduction, and gamete formation are incorrect answers.

b. Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accomodate the product.
c. Once the enzyme binds to a specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
