The answer is (1)


In the cell of the body, oxygen is used in a process that releases energy. Oxygen is used in the last and most important step in cellular respiration namely the electron transport chain.

In this process electrons are passed from one electron carrier to another and as they are  thus transferred, energy is released. Toward the final step, electrons are transferred  to oxygen which is the final acceptor of the electrons. By the time the process ends, 34 ATP molecules are produced.

What are the differences between aggregate fruit and multiple fruit ​
Dmitry_Shevchenko [17]

Answer:

Aggregate fruit is a fruit that develops from several ovaries forming one flower. An example of an aggregate fruit is a raspberry. Multiple fruit is fruit that develops from a cluster of flowers, and each flower produces a fruit, which turns into a mass of a singular fruit. An example of multiple fruit is a pineapple. Each "cube" of a pineapple is a separate fruit formed from a single flower, yet the pineapple as a whole is one mass of pineapple.

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)
