This is an example of negative mutation. Negative mutations produce a phenotype that acts antagonistically to the wild-type phenotype. On the other hand positive mutation produce a phenotype that acts synergistically to the wild-type phenotype.
The negative mutation will negatively affect the long term survival of the butterfly species as the mutation makes the new butterfly offsprings more visible to predators.

Explanation:
A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Each atom has a certain electro-negativity. When bonded to another atom, the atom with the higher electro-negativity will tend to attract more electrons.
B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
C) Weak electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
D) Weak electrolytes dissolve and does not dissociate in water providing no charged ions to conduct electricity.
Answer: B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
Explanation: Weak electrolytes are those substances which do not dissociate completely when dissolved in water. They dissociate but then associate back and thus their dissociation is shown by an equilibrium sign. Example:
The charged species formed helps in the conduction of electricity.
Strong electrolytes are those substances which dissociate completely when dissolved in water. Their dissociation is shown by a forward arrow. Example:
The charged species formed helps in the conduction of electricity.
Answer:
3.6*105g CH4
Explanation:
The detailed solution is shown on the image. From the detailed chemical reaction, we calculate the mass of methane required in the standard combustion reaction of methane and use it to estimate the mass required to produce the quantity of heat required in the question.
To supply the energy needed for an average home in Colorado, approximately 3.58 x 10^8 grams of natural gas (methane) must be burned.
To calculate the amount of natural gas (methane) required to supply the energy needed for an average home in Colorado, we can use the balanced chemical equation for the combustion of methane:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
The molar enthalpy change for this reaction (ΔH°rxn) is -890.4 kJ/mol. First, we need to convert the energy requirement from kilojoules to joules:
2.00 x 107 kJ = 2.00 x 1010 J
Next, we can use the molar enthalpy change to calculate the number of moles of methane required:
moles of CH4 = energy requirement / mlar enthalpy change
moles of CH4 = 2.00 x 1010 J / (-890.4 kJ/mol)
Finally, we can convert the number of moles of methane to grams using the molar mass of methane:
molar mass of CH4 = 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol
grams of CH4 = moles of CH4 * molar mass of CH4
Therefore, the number of grams of natural gas (methane) that must be burned to supply this energy is approximately:
grams of CH4 = (2.00 x 1010 J / (-890.4 kJ/mol)) * 16.04 g/mol
Simplifying the calculation:
grams of CH4 ≈ 3.58 x 108 g
