Answer: Vestigial structures
Explanation: Vestigial structures are an anatomical feature or behavior that no longer seem to have any purpose in the present form of an organism in the given species. Usually, they are often parts of the body that used to preform important functions in earlier forms of the organism.
No a cell lyse would be hypertonic.
Answer: The lagging strand glows more because its RNA primer is nearer the replication fork.
During DNA replication process, both the strands of DNA are replicated simultaneously in opposite direction. One strand is replicated continuously and known as leading strand while the other strand is replicated discontinuously and known as lagging strand. The leading strand has only one primer attached to it while the lagging strand
An adaptation occurs when a species is set through a new constraint. This can be change in climate, defense mechanisms, food source, etc. Which will have to occur before an adaptation is made. For an example: in North America the climate slightly swifted. This meant smaller mammals such as rabbits would need to have a thicker coat of fur or shelter. Let's say all the thin furred rabbits died and all that remained were the thick furred rabbits. Over a span of time the rabbits have adapted through the climate. Meaning most of the population is thick furred through their DNA. Conclusively, it's a genetic characteristic that can happen very rapidly or slowly.
I hope this solved your question!
