Sixty flowering plants are planted in a flowerbed. forty of the plants are red-flowering homozygous dominant. twenty of the plan

ts are white-flowering homozygous recessive. the plants naturally pollinate and reseed themselves for several years. in a subsequent year, 178 red-flowered plants, 190 pink-flowered plants, and 52 white-flowered plants are found in the flowerbed. use a chi-square analysis to determine if the population is in hardy-weinberg equilibrium

Answer:

The flowering population is in Hardy Weinberg equilibrium.

Step by Step Explanation:

Total initial population size = 60

As both the populations are homozygous so the frequency of alleles will be,

P = 80/120= 0.66

q = 40/120= 0.33

The predicted frequencies for genotypes once the population has reached Hardy-Weinberg

p2 = 0.4356

2pq= 0.4356

q2 = 0.1089

The number of plants with each type of flower in a papulation of 420 is,

Homozygous dominant= 185

heterozygous= 185

Homozygous recessive= 50

Chi square analysis:

The observed values for red-flowered plants, pink-flowered plants, and white-flowered plants are not significantly different from the expected values predicted by Hardy Weinberg equilibrium.

Phenotype      observed(o)    expected (e)          (o-e)2/e

Red                        178                 185                       0.26

Pink                       190                 185                       0.135

White                     52                   50                     0.08

                                       chi-square = 0.474

With 2 degree of freedom this chi-square gives a p value of 0.7 - 0.8, which is not significant.

In what way did Shakespeare create a distinction between the educated nobility and the coarse lower classes?
stiv31 [10]
<span>This is a very simplistic question because the distinction was clearly maintained in real life and that was only carried forward into Shakespeare's plays. The most obvious difference between people of different social classes was their clothes. People were forbidden by law to dress in certain ways unless they were rich and noble enough. The costumes used in the plays showed this: the actors playing noble people wore fine clothing (the castoffs of the real nobility). 
</span><span>
</span><span>The other difference between the upper and lower class people is the way they talk. Shakespeare often puts a stately blank verse in the mouths of the upper crust and arrhythmic prose in the mouths of the common people. But not always. Even the nobility speak in prose when they are disturbed or insane, and they speak in prose all the way through Much Ado About Nothing. Prince Hal talks in prose when talking to Ned Poins. Blank verse is saved for matters of seriousness where a more poetic approach is needed. It is not, therefore, a matter of social class so much as a matter of the weightiness of what is being said (and in Shakespeare, the lower classes rarely have anything worthwhile to say).</span>

How is the range of a data set determined
Sati [7]
The range of a set of data is the difference between the highest and lowest values in the set.

And to find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

ANEK [815]

Answer:

  1. T. Natural Reseeding.
  2. D. Species Diversity
  3. A. Ecosystem Diversity.

Explanation:

Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.

Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.

Korolek [52]

Answer:

C. Reactant and product concentrations in the test tube are different from those in the cell.

Explanation:

Cells convert some of the energy from ATP hydrolysis in to different forms of energy other than heat. ATP energy does not always generate more heat.  Many times, energy is used for different purposes.
