<span>If a population is not in Hardy-Weinberg equilibrium that can cause deviations from expectation depending on the assumptions of HW that are violated. If a population violates some of the assumptions (like mutations, migrations and selection) the allele frequencies will change over time. Also, if a non-random mating occurs (like inbreeding), it will cause an increase in homozygosity for all genes.</span>
Answer:
the base sequence would be GAA UAG GUA
Explanation:
Compared to DNA, RNA uses uracil instead of thymine, therefore every T changes to U.
Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
Explanation:
Scientists recognize seven living species of sea turtles, which are grouped into six genera. Each sea turtle has both a scientific name and a common name. The scientific name identifies the genus and species, and the common name typically describes some characteristic of the turtle’s body.
Different species of sea turtles like to eat different kinds of food. Sea turtles have mouths and jaws that are specially formed to help them eat the foods they like. And each species of sea turtle eats, sleeps, mates and swims in distinctly different areas. Sometimes their habitats overlap, but for the most part they each have different preferences.
