When the polymerase chain reaction (PCR) is used to amplify segments of DNA, the sample is first heated, and then cooled, in cyc

baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

${2^n - (2 * n)}$

where "n" is the number of PCR cycles.

It is given that DNA strands to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA

djverab [1.8K]

Answer:

Option C, Correct Behavior genetics

Explanation:

Behaviour genetics is the study of the influence of both genes and environment on the behaviour of an individual. This study is done to understand how both genes and environment together affect the behaviour of an individual. It is believed that all forms of behaviors are either inherited or learned. Mr. Hill is noting the concordance rates of music ability for both biological children (who might have inherited this ability from their parents) and adopted children (who might have learned this ability from the musical environment around them)

Hence, option C is correct

In the table on the right, observe Krakauer's formula for benefit to dominant male. What is the benefit, B? calculate the value

Mashcka [7]

The table is an illustration of two-way table, and the value of the cost to net benefit to subordinate male is 0.1

<h3>The value of the benefit</h3>

From the table, the Krakauer's formula for benefit (B) is:

B = Offspring per dominant male - Offspring per solo male

The question has missing parameters, so we make use of the following assumed values:

Offspring per dominant male = 7
Offspring per solo male = 2

So, we have:

B = 7 - 2

B = 5

Using the assumed values, the value of the benefit is 5

<h3>The cost to subordinate male</h3>

The Krakauer's formula for cost (C) is:

C = Offspring per solo male - Offspring per subordinate male

Given that subordinate male never reproduce, the equation becomes

C = Offspring per solo male - 0

C = Offspring per solo male

Using the assumed value in (a), we have:

C = 2

Using the assumed values, the value of the cost to subordinate male is 2

<h3>The net benefit to subordinate male</h3>

The Krakauer's formula for this is:

Net Benefit = rB - C

Given that r = 0.42, the equation becomes

Net Benefit = 0.42 * 5 - 2

Evaluate

Net Benefit = 0.1

Using the assumed values, the value of the cost to net benefit to subordinate male is 0.1
