researchers conducted an experiment to identify the effects of three different hand sanitizer on the growth of bacteria the rese

archers grew one type of bacteria and 24 identical covered Petri dishes then they open 18 Petri dishes and applied for three hand sanitizers to six Petri dishes Beach they left the remaining six Petri dishes closed as a control when the researchers measure the growth of bacteria 2 Days Later the six dishes that had no hand sanitizer showed the least amount of bacterial growth the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth which statement best explains why the researchers conclusions were not justified

Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.

small group of 100 people decide to isolate themselves from the world and move to a small and remote deserted island. Out of thi
irina [24]

Answer:

Frequency of p = 0.684

Frequency of p = 0.316

Number of individuals with homozygous dominant (AA) = 47

Number of individuals with heterozygous (Aa)= 43

Number of individuals with homozygous recessive (aa) = 10

Explanation:

Out of 100 people, 10 have albino skin (aa)

So, the frequency of homozygous recessive individuals (q^{2}) is \frac{10}{100} = 0.1

Now, q will be

= \sqrt{q^{2} } = \sqrt{0.1} \\= 0.316

As per Hardy Weinberg's equation -

p + q = 1

Substituting the value of q in above equation, we get -

p + 0.316 = 1p = 1 -0.316\\p = 0.684

Now the frequency of homozygous dominant (AA) will be

p^{2} = 0.684^{2} \\= 0.467

Hence, out of 100 people 0.467 * 100 = 46.7 or 47 people are homozygous dominant (AA)

Like wise out of 100 people 0.1 * 100 = 10 people are homozygous recessive (aa)

As per As per Hardy Weinberg's equation-

p^{2} + q^{2} + 2pq = 1\\

Substituting the values in above equation, we get -

0.467 + 0.316 + 2pq = 1\\2pq = 1 -( 0.467+ 0.1)\\2pq = 0.433

So, out of 100 people 0.433 * 100 = 43.3 or 43 people are heterozygous (Aa)
