<span>Well, deep ocean trenches form on a specific type of plate boundary called a subduction zone, and these zones occur when an ocean plate collides with another ocean plate. Hope I helped.</span>
Answer:
0.5
Explanation:
let the alleles be W- no white spots w-white spots
ww butterflies have white spots
genotypic frequency of ww= number of butterflies with white spots/total number
= 128/512
= 0.25
alleleic frequency of w= square root of genotypic frequency of ww
= square root of 0.25
= 0.5
Hello User!
Answer:
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
Answer:
C. Bilateral symmetry
Explanation:
Just before the Cambrian explosion, approximately 600million years ago, multicellular aquatic animals are thought to have developed new body plans. As a result they split into two groups of organisms which were notably radially symmetrical and bilaterally symmetrical. These early bilaterally symmetrical animals were simple organisms without a body cavity called a coelom; further evolution, led to the development of complex coelomates. Eventually, land-dwellers capable of respiring out of water with the aid of lungs emerged, and subsequently, their adaptations allowed for reproduction in their new habitats.
