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

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)

What is the first form of chemical digestion that food encounters when entering the digestive system? A.molars B.pepsin C.saliva
Archy [21]

Answer:

Chemical digestion actually starts in the mouth when our saliva mixes in with the food. So, A. wouldn't really be correct. It's not the molars that are doing the chewing, but rather your jaw muscels. I don't even know what pepsin is... <u>C. would probably be your best bet because it's your saliva that breaks down your food and helps you chew it.</u> And D. your tongue just helps to move the food around...

Explanation:

Hope this helps you!!!
