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 
Answer:
B. rr
Explanation:
Genotype- Is the genetic makeup of an organism.
An homozygous individual is one who has similar allele e.g AA
It could either be in dominant form(AA) or recessive form(aa)
An heterozygote individual has two different allele in its genotype e.g Aa
A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.
The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.
The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.

glucose, energy, water, oxgen
Explanation:
C because the moon has less mass than Earth the Gravitational Force is less and thus anything on the moon weighs less than on Earth
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Benioff Zone.
