Peppered moths come in two colors, black and white. What did Kettlewell show, with regard to peppered moth populations and tree

coloring? (Recall that England at the time was heated mainly by coal in urban areas.) A) In smoggy areas, dark moths have a higher survival rate than white moths. B) White moths stand out in rural areas, and quickly disappear from those areas. C) The black moth and white moth forms were actually two different species of moths. D) Environmental conditions do not affect physical features of a species over a short time period.

Answer is: A) In smoggy areas, dark moths have a higher survival rate than white moths.

The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.

This is example of natural selection and adaptation.

Predators will easily capture white moths and their population will drope.

Moth populations can survive in a variety of different situations, because the environment is constantly changing and different alleles are favored.

A is the answer because the trees turned blackish from the coal so moths that were black could camouflage on those trees easier.

What is the mole fraction of NaOH in an aqueous solution that
astraxan [27]

Answer:

The mole fraction of NaOH in an aqueous solution that contain 22.9% NaOH by mass=0.882

Explanation:

We are given that

Aqueous solution that contains 22.9% NaOH by mass means

22.9 g NaOH in 100 g solution.

Mass of NaOH(WB)=22.9 g

Mass of water =100-22.9=77.1

Na=23

O=16

H=1.01

Molar mass of NaOH(MB)=23+16+1.01=40.01

Number of moles =\frac{Given\;mass}{Molar\;mass}

Using the formula

Number of moles of  NaOH(n_B)=\frac{W_B}{M_B}=\frac{22.9}{40.01}

n_B=0.572moles

Molar mass of water=16+2(1.01)=18.02g

Number of moles of water(n_A)=\frac{77.1}{18.02}

n_A=4.279 moles

Now, mole fraction of NaOH

=\frac{n_B}{n_B+n_A}

=\frac{4.279}{0.572+4.279}

=0.882

Hence, the mole fraction of NaOH in an aqueous solution that contain 22.9% NaOH by mass=0.882
