Why do children tend to have high-pitched voices, and why do males typically have lower voices...
Homework Answers
A child has short vocal cords, they produce short air waves and consequently a high pitched voice. As a child grows, the vocal cords become longer. That causes the voice to become deeper. Thus the voices of adults are heavier and deeper than children’s voices.
Testosterone present in males makes the vocal cord thicker and longer which results in the generation of low pitched sounds as compared to females.

Among individuals with schizophrenia, research shows that 1) females tend to have a better long-term prognosis, and 2) onset of this disorder tends to be slightly earlier for males than it is for females. Given the information above, discuss the mechanism/explanation for why women have better prognosis than men. You will have to use and synthesize both pieces of the information above.

1. Primate females always invest in their young because primate males do not have the appropriate neurological foundation. they produce large, nutrient-rich gametes. parenting effort is equal to mating effort. they are committed to parental investment by their physiology. 2. Which of the following is true of primates in general? One-male, multifemale groups have less dimorphism in body size than do pair-bonded species. Pair-bonded groups have the least amount of sexual dimorphism in body size. Multimale, multifemale groups tend to...

A survey asked, "How many tattoos do you currently have on your body?" Of the 1214 males surveyed, 186 responded that they had at least one tattoo. Of the 1073 females surveyed, 133 responded that they had at least one tattoo. Construct a 90% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let P, represent the proportion...
