Two goldfish different parents.One fish has a split tail and the other does not.Why do the goldfish have tails with different sh

apes?
a.Each goldfish has a different tail shape because offspring from different parents will have different tail shapes.

b.Each goldfish has a different tail shape because they have different versions of the gene for tail shape that connect together to make different tail shapes.

c.The goldfish have different versions of the gene for tail shape.The genes are split inside one goldfish's tail but not inside the other's

The goldfish have different versions of the gene for tail shape,which instuct for different proteins that connect in different ways to make different tail shapes.

Which of these statements best explains why the soil around a volcanic region is fertile?
AVprozaik [17]

Answer:

The correct statement is option c, that is, particles discharged in the air by volcanoes fall to the ground and enrich the soil.  

Explanation:

The eruptions of volcanoes lead to the dispersion of ash over the broader regions surrounding the site of eruption. On the basis of the chemistry of the magma, the ash will be comprising different concentrations of soil nutrients. While the major elements found in the magma are oxygen and silica, the eruptions also lead to the discharging of carbon dioxide, water, hydrogen sulfide, sulfur dioxide, and hydrogen chloride.  

In supplementation, the eruptions also discharge bits of rocks like pyroxene, potolivine, amphibole, feldspar that are in turn enriched with magnesium, iron, and potassium. As an outcome, the areas which comprise huge deposits of the volcanic soil are quite fertile.

What rules should you follow when adding and subtracting? Check all that apply.
GaryK [48]

Answer:

The answer to this question would be:  

2. The exponents need to be the same so the leading numbers can be added or subtracted.

3. The result has the same number of decimal places as the least precise number.

The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5

The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.

eimsori [14]

Answer:

P_{met}=40.98mmHg\\\\P_{et}=24.82mmHg

Explanation:

Hello

In this case, by considering the Raoult's law we can write:

P_{met}=x_{met}P_{sat,met}\\\\P_{et}=x_{et}P_{sat,et}

Whereas the purpose is to compute the pressures of both methanol and ethanol (pressures above the solution), thus, the first step is to compute the molar fractions:

n_{met}=25.3gCH_3OH*\frac{1molCH_3OH}{32gCH_3OH}=0.791molCH_3OH\\ \\n_{et}=47.1gCH_3CH_2OH*\frac{1molCH_3CH_2OH}{46gCH_3CH_2OH}=1.02molCH_3CH_2OH\\\\x_{met}=\frac{0.791mol}{0.791mol+1.02mol}=0.436\\ \\x_{et}=1-x_{met}=1-0.436=0.564

Therefore, the pressures turns out:

P_{met}=0.436*94mmHg=40.98mmHg\\\\P_{et}=0.564*44mmHg=24.82mmHg

Best regards.
