Which statement best describes the formation of metamorphic rocks? 1. Magma cools and crystallizes slowly beneath Earth’s surface. 2. Liquid lava erupts from a volcano and cools quickly at Earth’s surface. 3. Sand and gravel are deposited at the mouth of a river and, over time, form layers that solidify into rock. 4. Ancient sandstone beaches become buried deep beneath the Earth’s surface, where they are exposed to extreme heat and pressure.

Genetic diversity is the variation in the genes of an entire species. each circle represents a population of a particular species in different habitats. select the population with maximum genetic diversity

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?

Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) receptively. what is the probable genotypes of the round seeds which produced f 1 ? rr & rr rr only rr & rr rr only rr only
