Which of the following statements best describes what will most likely occur to the moth populations in the image below?

1 answer:

5 0

Answer is: A. 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 amd 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.

Genetic variation is important to the population's ability to survive in different situations that affect natural selection. New habitat and increased food supply can increase genetic variation.

The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula:

uysha [10]

Answer:

The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.

Explanation:

Energy of the electron in a hydrogen atom in nth shell:

$E=\frac{-R_y}{n^2}$

$R_y=2.178\times 10^{-18} J$

Energy of an electron in n = 2:

$E_2=\frac{-R_y}{2^2}=-\frac{R_y}{4}$

Energy of an electron in n = 3:

$E_3=\frac{-R_y}{3^2}=-\frac{R_y}{9}$

Energy difference in between both the shells:

$\Delta E=E_3-E_2$ :

$=-\frac{R_y}{9}-(-\frac{R_y}{4})=\frac{5R_y}{36}$

$\Delta E=\frac{5R_y}{36} =\frac{5\times 2.178\times 10^{-18} J}{36}$

$=3.025\times 10^{-19} J$

$\Delta E=3.025\times 10^{-19} J=\frac{hc}{\lambda}$

$\lambda =\frac{hc\times 36}{3.025\times 10^{-19} J}$

= $\frac{6.626\times 10^{-34} J s\times 3\times 10^8 m/s}{3.025\times 10^{-19} J}$

$\lambda =6.571\times 10^{-7} m=657.1 nm$

$1 m = 10^9 nm$

The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.

The compound gallium phosphide (Ga P) is a compound semiconductor having mixed ionic and covalent bonding. The electronegativiti

alexandr1967 [171]

Answer: The fraction of the bonding that is ionic is 0.08875.

Explanation:

Percentage ionic character is calculated using the formula:

% ionic character = $[16\times \Delta E_N + 3.5\times (\Delta E_N)^2]$

Where, $\Delta E_N$ = electronegativity difference

Given : The electronegativities for Ga and P are 1.6 and 2.1 respectively.

Thus $\Delta E_N$ = electronegativity of phosphorous - electronegativity of galium = 2.1 -1.6 = 0.5

Therefore,

%ionic character = $[16\times 0.5 + 3.5\times (0.5)^2]=8.875$

Fraction of ionic bond = $\frac{8.875}{100}= 0.08875$

The fraction of the bonding that is ionic is 0.08875.
