Answer:

Effect on climate change.

Resource deplition.

Global warming.

Air polution.

Water contamination.

Explanation:

Humans are known for being too lazy to throw their trash in an actual trash can, thus leading to water contamination from people throwing trash in the water.  Air polution tends to come from nuclear factories and gas powered cars. Resource deplition, like mass tree cutting for building buildings.

Which policy would most likely decrease a city's gasoline use <br>​
Daniel [21]

Make sure the gas cap is on tight. One reason you may not be getting the mileage you expect is because there isn't as much gas in your tank as you think. 147 million gallons of gas were lost last year due to evaporation. Why did it evaporate? The gas cap was not on tight. So just make sure it is tight, and it will enable you to keep all the gas you pay for

Roberta makes a $9 an hour plus a 12.5% commission selling jewelry how much does she earn on a 8 hour shift which she sells $380
aivan3 [116]

Answer:

The amount Roberta makes an hour is $119.5

Explanation:

Let the number Roberta makes be x hours.

Amount earned in x hours shift - 9*x + 12.5% of the amount of jewelry sold.

Number of hours worked by Roberta if 9 hours and jewelry worth $380 is sold by her.

Substituting the values:

Amount earned in an 8 hour shift = 9*8 + 12.5% od 380

= 72 + 0.125 * 380 (12.5% = 0.125)

= 12 + 47.5

= 119.5

A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and t<span>he frequency of i allele is 0.5.
</span>
If:
I^{A} - <span>the frequency of IA allele
</span>I^{B} - <span>the frequency of IB allele
</span>i - t<span>he frequency of i allele

Then:
</span>I^{A} I^{A} + <span>I^{A} i - the frequency of individuals with A blood type
</span>I^{B} I^{B} + <span>I^{B} i - the frequency of individuals with B blood type
</span>ii <span>- the frequency of individuals with O blood type
</span>
Let's first take a look on the Dunker population:
I^{A} = 0.3
ii=0.16&#10;

<span>Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
</span>i= \sqrt{ii}
⇒ i =  \sqrt{0.16}
⇒ i=0.4

Now, we have the frequencies of two alleles (I^{A} and i). To calculate the frequency of I^{B}<span> allele, we will use the formula:
</span>I^{A} + I^{B} + i = 1
⇒ I^{B} = 1- I^{A} - i
⇒ I^{B} = 1-0.3-0.4
⇒ I^{B} = 0.3

Now, in the general population:
I^{A} = 0.4
ii=0.25

<span>Similarly to the work for the Dunker population:
</span>i= \sqrt{ii}
⇒ i = \sqrt{0.25}
⇒ i=0.5

I^{A} + I^{B} + i = 1
⇒ I^{B} = 1- I^{A} - i
⇒ I^{B} = 1-0.4-0.5
<span>⇒ I^{B} = 0.1
</span>


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.
