6. aa and cc ; two lower-case letters indicate the expression of a recessive trait because there is no dominant trait to mask it. (Dominant alleles are capitalized).
7. 1 pp (lower case = recessive)
7.2 Pp, PP; because the white flower is pp, the flower's recessive trait is white. White will only be expressed in the absence of a P, the dominant gene. If a P is in the genotype, it will mask the p allele' causing the flower to be purple.

Answer:
42.8
Explanation:
Let's consider the following reaction at equilibrium.
CO(g) + 2 H₂(g) ⇌ CH₃OH(g)
The concentration equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.
The concentration equilibrium constant for this reaction is:
The given equilibrium reaction is,
The given reaction is exothermic. So, heat energy will be a product. Therefore, decreasing the temperature (heat energy) would lead to the formation of more products as when the amount of energy which is a product is reduced, there is more room for the products to form.
Increasing the pressure would shift the equilibrium towards that side which has least number of moles of the gaseous substance. Hence, here increasing the pressure would lead to the formation of more products by shifting the equilibrium towards the right side.
Decreasing the volume would make the equilibrium shift towards the least number of moles of the gaseous substance. So, here in this equilibrium decreasing the volume would lead to the formation of more products.
Answer:
158 mL
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 99.0 KPa
Initial volume (V₁) = 300 mL
Final pressure (P₂) = 188 KPa
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
99 × 300 = 188 × V₂
29700 = 188 × V₂
Divide both side by 188
V₂ = 29700 / 188
V₂ = 158 mL
Therefore, the final volume of the gas is 158 mL.
