Darwin called this idea of certain traits being selected in order for an organism to reproduce sexual selection. In crickets and

frogs, males call to attract mates and females are attracted to superior males by characteristics of their calls. How can this also be a disadvantage to survival of the species? A) Only the superior male traits are passed to the next generation. B) Female choice for mating reflects only the genes of the superior males. C) Calling can be hazardous because it also attracts parasites and predators. D) Inferior males intercept the females from the superior males and mate anyway.

Th correct answer is option C. Calling can be hazardous because it also attracts parasites and predators.

The mating call is used by the males to attract females for sexual reproduction. By using vocal sounds males are not only making themselves attractive to females, they are also making themselves vulnerable to predators.

Thus the mating call can have a disastrous effect on the survival of the species.

Assuming that all the energy given off in the reaction goes to heating up only the air in the house, determine the mass of metha
nirvana33 [79]

Answer:

0.92 kg

Explanation:

The volume occupied by the air is:

35.0m\times 35.0m \times 3.2m \times \frac{10^{3}L }{1m^{3} } =3.9 \times 10^{6} L

The moles of air are:

3.9 \times 10^{6} L \times \frac{1.00mol}{22.4L} =1.7 \times 10^{5}mol

The heat required to heat the air by 10.0 °C (or 10.0 K) is:

1.7 \times 10^{5}mol \times \frac{30J}{K.mol} \times 10.0 K = 5.1 \times 10^{7}J

Methane's heat of combustion is 55.5 MJ/kg. The mass of methane required to heat the air is:

5.1 \times 10^{7}J \times \frac{1kgCH_{4}}{55.5 \times 10^{6} J } =0.92kgCH_{4}

You have 8 moles of a gas at 250 K in a 6 L container. What is the pressure of the gas? Show your work
Bogdan [553]

Hello:

In this case, we will use the Clapeyron equation:

P = ?

n = 8 moles

T = 250 K

R = 0.082 atm.L/mol.K

V = 6 L

Therefore:

P * V = n *  R * T

P * 6 = 8 * 0.082* 250

P* 6 = 164

P = 164 / 6

P = 27.33 atm


Hope that helps!

How many moles are in 158 grams of LiCl
Usimov [2.4K]

Answer:

Number of moles = 3.73 mol

Explanation:

Given data:

Mass of LiCl = 158 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of LiCl = 42.4 g/mol

Number of moles =  158 g / 42.4 g/mol

Number of moles = 3.73 mol
