Which of the following is a problem associated with hands-free devices? a. they cause drivers to fixate on the car in front of them. b. they require extra attention due to poor reception. c. they use a number of small, hard-to-reach buttons.

The correct answer is option B, that is, they require extra attention due to poor reception.

The hands-free devices have an issue, as it can lead to mishaps. When a person tries to focus on more than one activity, the brain may become burdened by the requirement to process information from two or more sources.

Additionally, whenever a person switches between the errands, the brain must devote energy and time redirecting its attention rather than thinking. The more information the brain has to sort at a particular time, the more probability is to suffer from inattention blindness and miss essential clues about the situation of the road.

Thus, to be a safe driver, there is a need to develop mental discipline to remain aimed at a single task as long as the person is driving on the road.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
