Answer:
b. 245
Explanation:
The Formula proposed by Hardy- Weinberg Equilibrium is:
p + q = 1
p² + 2pq + q² = 1
p is the frequency of the dominant allele.
q is the frequency of the recessive allele.
p² is the frequency of individuals with the homozygous dominant genotype.
2pq is the frequency of individuals with the heterozygous genotype.
q² is the frequency of individuals with the homozygous recessive genotype.
From the question, we were told that;
blue wing color is determined by a dominant allele (B) = p = 0.3
Then we are tasked with finding the frequency of recessive green allele (G). = q ???(unknown)
From above equation; we have :
p + q = 1
Since p = 0.3, we can find q
q can now be ;
q = 1 - p
q = 1 - 0.3
q = 0.7
If q = 0.7;
then q² = (0.7)²
q² = 0.49
We can now multiply the frequency of individuals by the total population in order to get the number of individal with the given genotype were are tasked to find;
So, we have:
= 0.49 × 500
= 245
∴ From the total population; there are 245 green winged butterflies in population of 500 butterflies.

The answer is that all of them are dicots.
The angiosperms are the flowering plants. They are divided into two classes - the dicots and monocots. The monocots have one cotyledon in the seed while the dicots have two cotyledons in the seed. However, if we cannot assess the number of cotyledons, we can look at some morphological characteristics of monocots and dicots:
- The monocots have petals in multiples of three. The dicots have petals in multiples of four of five.
- The monocots have parallel leaf vein. The dicots have reticulated leaf veins.
So, none of those flowers have petals in multiples of three and they have reticulated leaf veins. Therefore, they all must be dicots.
