The answer is d.) mantle rock
Answer: D.600 minutes
Explanation:At 70 percent it takes about 450 minutes, so it should take about 600 minutes at 90 percent.
They are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations
Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.
Hence we can conclude that Natural selection , mutation, genetic drift and gene flow are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations

Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
Explanation:
A recessive trait is a trait that have been expressed when an organism has two recessive alleles or two forms of a gene.
Traits are called the physical/non-physical characteristics of a organisms that can or cannot be observed.
Physical characteristics like hair, eye color can be observed while other characteristics like the shape of blood cells cannot be observed.
It is important to note that if the trait is dominant, one of the parents will have the trait. Dominant traits does not skip a generation. In case the trait is recessive, neither of the parent will have the trait .Recessive trait can skip a generation
So we can say that in the case mentioned in the question
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
