Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

On a dichotic listening task, A. people can accurately monitor two tasks at the same time, except when the tasks are both audito

RideAnS [48]

Answer:

B. people notice little about the message that they are supposed to ignore

Explanation:

In dichotic listening task people are able to concentrate on one voice while ignoring the other. It is observed that during dichotic listening task people concentrate more on one task than other. Sometimes dichotic listening task is used to examine the selective attention of brain. In the test the person is subjected to two voices simultaneously over the headphones and asked to pay attention either one or both voices. Then he is aked questions about the content.

Example; If you are talking on the phone with someone in a room filled with voices of other people, you would be able to listen and concentrate at the voice on the phone while ignoring the other voices because of dichotic listening.

Example; If you are attending a seminar of a psychology professor and some peoples are talking in the hall you would be able to concentrate on the voice of the professor because of dichotic listening.
