Explanation:
In corn,
Smooth kernel (S) is dominant to rough kernel (s)
Purple kernel (P) is dominant to yellow kernel (p)
Since no information has been given about the cross here let us assume it to be a standard dihybrid cross.
The phenotypic ratio of dihybrid cross is 9:3:3:1. 9/16 will show dominant phenotype for both traits, 3/16 will show dominant phenotype for one trait, other 3/16 will show dominant phenotype for the second trait, 1/16 will have recessive phenotype for both the traits.
Here,
Purple rough (P_ss) = 52
Yellow smooth (ppS_) = 50
Both of them show dominant phenotype for one trait so they each form 3/16 of the progeny.
If the total progeny was z, 3/16*z = 50
z = (50*16)/3 = 267
Total progeny = 267 kernels
Yellow rough kernels (ppss) = (1/16*267) = 17
So approximately 17 corn kernels will be yellow and rough.
Answer: At sea level and at a temperature of 0° Celsius (C), the height of the mercury column is approximately 30 inches, or 76 centimeters. This represents a pressure of approximately 14.7 psia. The 30-inch column is used as a reference standard. Atmospheric pressure does not vary uniformly with altitude.
Answer:
I think they could feel around in the water to see where they are going and they probably just know their way like for food it might be hard but I am sure they eventually find it.
Explanation:
Cells are usually in the S Phase because it takes longer to complete
