Assuming the white phenotype is recessive. white: gg
I think the gray mouse is Gg because the offspring were pretty equally distributed in terms of color. See the punnet square below.
g g
G| Gg Gg
g| gg gg
If the Gray phenotype is recessive, then gray: ww but only if white is Ww because its about 50% chance for both.
Answer:
ppss and PPSS
Explanation:
Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.
And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.
A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.
Thus, the genotypes of the parental flies in Cross 1 are
PPSS and ppss
The process is called precipitation. This is when water released from clouds in the form of rain,freezing rain,sleet,snow or hail. It is the primary connection in the water cycle that provides delivery of atmospheric water to the Earth.

Answer: b. dead at maturity and are used to transport sugars throughout the plant.
Phloem cells are the cells which transport the product of photosynthesis that is food from the leaves to other parts of the plant. A typical phloem consist of sieve cells, phloem fibers, and phloem parenchyma. Sieve cells are elongated and they have minute pores which facilitates the transport of food through these pores. The phloem fibers provides mechanical support to the phloem. Phloem parenchyma cells are responsible for the storage of food. The process by which phloem transport food is called as translocation. Sieve cells are the main type of cells helps in food translocation, in maturity these cells looses their nucleus and ribosomes therefore, they die in maturity.
