In pea plants, the allele for tallness is dominant (T) to the allele for shortness (t). A pea plant that is tall (TT) is mated with another pea plant that is short (tt). Which of the following is correct about their offspring? (Do a Punnett square if needed!) * 1. Half (50%) of the offspring will have the dominant allele
2. All of the offspring will be short
3. All of the offspring will be tall
4. Half (50%) of the offspring will carry the recessive allele

3. All of the offspring will be tall

Your brain is able to do this by comparing tiny differences in the way that sounds affect each ear. A noise coming from the right is slightly louder in your right ear, and reaches it fractionally earlier than your left. A sound in front or behind affects each ear the same way, with intermediate effects in-between. The brain uses these differences, even as small as a 100,000th of a second, to calculate where the sound is coming from. Signals from the ear travel along the auditory nerve to the brainstem, where each individual cell responds to a specific time difference and direction. Until recently it was assumed that a delay was imposed somewhere between the ears and the brainstem, but it has now been discovered that all of the calculations are done in the brainstem cells, which then signal the result to other parts of the brain – enabling you to hear the sound and  know, without thinking, just where it’s coming from.HOPE IT HELPS !!!
