Answer:
Genotype of long winged fly is Ll
Genotype of short winged fly is ll
Explanation:
Given
Allele for long wing trait is "L"
Allele for short wing trait is "l"
When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 
Let us say that the genotype of long winged fly is Ll
and the genotype of short winged fly is ll
The cross between the two will produce following offspring
Ll * ll
Ll, Ll, ll, ll
Out of four off spring two have long wings (Ll)
and the other two have short wings (ll)
Thus the ration of long to short wing offspring is 
i.e
Remember for a di hybrid cross with two completely heterozygous parents, the phenotypic ratio will always be 9:3:3:1
9 will always display both dominant traits, black and rough hair. 3 will display black hair and smooth hair and 3 will display not black hair and rough hair and 1 will display both receive traits
Answer:
- Both processes form minerals.
- Volcanic eruptions form precipitates and shifting of tectonic plates form minerals.
Explanation:
Both volcanic eruptions and the shifting of tectonic plates form minerals. Volcanoes and their eruptions can directly or indirectly lead to the formation and/or deposit of minerals such as diamonds and zinc. Shifting also forms minerals due to the forces of compression the plates apply on each other as they move past.
Volcanoes are known the cause precipitates because when the erupt, the ash that is released mixes with water vapor which then becomes rain eventually.
The answer is most simply A
