What are you testing for when you use lugols solution

Dominik [7]

You are testing for the presence of starch: Iodine dissolved in an aqueous solution of potassium iodide - reacts with starch producing a deep blue-black color. This reaction is the result of the formation of polyiodide chains from the reaction of starch and iodine.

. In this example, red flower coloring is dominant to white, and your population of 200 plants has 150 plants with red flowers.

AnnyKZ [126]

Answer:

a) The allele frequencies are - $p= 0.8660\\q= 0.134$

b) Genotype frequencies for this population- $p^2=0.75, q^2= 0.0179, 2pq = 0.2321$

Explanation:

Given ,

Red color of flower is dominant to white color flower

Let "R" represents allele for red color and "r" represents allele for white color

out of $200$ flower, $150$ are red flowers.

So the frequency of red flowers with genotype "RR" is equal to

$p^{2} = \frac{150}{200} \\p^{2} =0.75$

As per hardy Weinberg's I equilibrium equation -

$p+q=1\\p=\sqrt{p^2} \\p=\sqrt{0.75} \\p= 0.8660\\q= 1-p\\q= 1-0.8660\\q = 0.134$

a) The allele frequencies are - $p= 0.8660\\q= 0.134$

Frequency of genotype "rr" i.e homozygous recessive white flower is

$q^{2} \\0.134^2\\q^2 = 0.0179\\$

Substituting the values of $p^2$ and $q^2$ , in below equation, we get -

$p^2+2pq+q^2=1\\2pq= 1-p^2-q^2\\2pq= 1-0.75-0.0179\\2pq=0.2321$

b) Genotype frequencies for this population- $p^2=0.75, q^2= 0.0179, 2pq = 0.2321$

Does graphite have a crystal pattern

Vikentia [17]

Yes

Explanation:

Graphite is one of the two allotropes of carbon. It is crystalline and has well ordered crystal patterns.

Graphite is made up of layers arranged in a hexagonal structure weakly bonded by van der waals forces.
Graphite structure is made up of hexagonal planes of carbon weakly bonded to one another.
This structure makes graphite soft and slippery and makes them applicable as lubricants.
The other crystalline type of carbon is diamond.
Diamond has close-packed crystal structure responsible for its extreme hardness.
The arrangement of these atoms permeates through the structure.
