Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The statement that best describes how the Great Rift Valley in Africa formed is that they formed when the crust pulled apart.
- This is geologically known as divergence.
- The Arabian plate and the Nubian/Somali plate are divergent plates.
- They are currently moving apart and away from each other.
- This creates a crack on the earth which is what formed the rift valley in Africa.
- Along such margins, earthquake activities are prominent.

Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
