The answer is;
A crack forms in oceanic crust.
Volcanoes erupt under the ocean.
Molten rock rises up through the crust.
New material pushes older rock away from the ridge.
Seafloor spreading occurs in divergent boundaries where two tectonic plates are moving away from each other. As the plates diverge, the void is filled up by upweling magma from the mantle. This causes an eruption at the boundaries causing a cascade of mountains along the ridge. Therefore, the closer to the ridge you get, the newer the crust is.
Answer:
when people recycle they really just need to pickup after themselves
Picture B
That is when the cell start to become two identical daughter cells
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
