2.)the continents seemed to fit together; they were like a spread apart puzzle.
3.)geographical features and mountain ranges lined up with the same rock composition
4.)glacier grooves in rocks led him to trace them out to where they started

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction between the air and the swing and between the chains and the attachment points slows it down and eventually stops it.
The correct answer for this question would be the first option. The reason that is most likely why fisheries management official recommends that long line fishing in a certain area be prohibited during the spring and summer season of the year is to prevent <span>the catching of sea birds during their nesting and breeding season. Hope this answer helps.</span>
Darwins's theory of natural selection is an evidence of evolution by acquiring characters that make survival of an organism feasible in a typical environment.
Fossils records are used to support this theory, by figuring out the common ancestry of different species and different traits that have evolved in them with time.
Embryology is also used as an evidence which shows common origin of the organisms. Other evidences are geographic distributions and homologous structures of the living organisms.
Double fertilization happens when one sperm cell wires with the egg to create a zygote, and the other sperm cell wires with the two polar cores to make the endosperm.
To answer the above:
Once double fertilization occurs in plants, the zygote is diploid and the endosperm is <span>triploid.</span>
