The brain controls what you think and feel,how you learn and remember and the way you move and talk. But it also controls things you' re less aware of - like the beating of your heart and the digestion of the your food
Answer:
This is an example of "Disruptive selection".
Explanation:
<em>Disruptive selection</em> occurs when <em>selective pressure</em> <em>favor homozygous</em>. In equilibrium, <em>the two alleles might be present or one of them might be lost</em>. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.
The disruptive selection causes an <em>increase</em> in the two types of <em>extreme phenotypes over the intermediate forms</em>. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.
Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the <u>extremes forms</u>. Individuals in <u>the middle</u> are not successful at survival or reproduction.
<em>Color</em> is very important when it comes to <em>camouflage</em>. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can <em>hide from predators</em> more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.
Answer:
a. Odds ratio = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning
Explanation:
For case study
Let 'a' represent the total population of people with melanomia = 696
Let 'b' represent the total number of people with melanomia exposed to indoor tanning = 1107 – 696 = 411 people
For control study
Let 'c' represent the total population = 1500
Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)
= 1500 - 723
Total number of people not exposed to indoor tanning = 777 people
a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)
= 1.69 / 1.07 = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
