Answer:
A. The smooth, clear rock layers
Explanation:
Earth is always rotating around the sun that means if it were winter on one side of the world, (that is not on the side of the sun) the other side of the world would be summer, ( the side that the sun is shining on)
Answer:
All the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Explanation:
Given
Tallness ( T) is dominant to dwarfness (t)
Red (R) flower color is dominant to white (r)
It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance
Genotype of dwarf red snapdragon is RRtt
Genotype of a plant homozygous for tallness and white flowers is rrTT
The punnet square representing the cross between RRtt and rrTT is as given below-
Rt Rt Rt Rt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
Thus all the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
a chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behavior or physiology of others of its species.
The answer is Nitrification.
