Explanation / Answer

1.Men emphasized on looks.Researchers found that men were significantly less willing than women to marry someone who was "not good looking" whereas women were significantly less willing than men to marry a partner who was "not likely to hold a steady job" and who would "learn less than you".Men emphasize more on physical attraction than women. 2.Certain singers have a distinctive “signature” to their voice that makes them recognizable even when they are singing an unfamiliar song. The distinctive variations in the complexity of a person's voice is known as timbre.Timbre, also called timber, quality of auditory sensations produced by the tone of a sound wave. The timbre of a sound depends on its wave form, which varies with the number of overtones, or harmonics, that are present, their frequencies, and their relative intensities. 3.Brandi is experiencing the elimination of connections among neurons that occurs when the connections are not needed for an organism's functioning. This process is known as neural pruning.Synaptic pruning refers to the process by which extra neurons and synaptic connections are eliminated in order to increase the efficiency of neuronal transmissions. 4.Gwen's haptic system provides her with information about:balance.haptic perception supplies the body's orientation system with information about its relative position in space. 5.In the cells of the body, genes are contained within chromosomes, biological structures that consist of highly organized, tightly packed strings of molecules. 6.A form of learning that occurs when an organism encounters a stimulus that repeatedly signals the occurrence of a second stimulus.
