All of these foods contain enormous amounts of carbohydrates. However, the cookie is the only one with processed sugar (unless you're crazy and add sugar in your stuff)!
If the mutation is beneficial, the mutated organism survives to reproduce, and the mutation gets passed on to its offspring. In this way, natural selection guides the evolutionary process to incorporate only the good mutations into the species, and expunge the bad mutations.
<h3><u>Answer;</u></h3>
d. before the Neogene era.
<h3><u>Explanation;</u></h3>
- <em><u>The Silurian Period was a third period of the Paleozoic Era that occurred from 443 million to 416 million years ago. This period occurred after the Ordovician Period and was then followed by the Devonian Period.</u></em>
- Silurian period is the period that many biologically significant events took place. There was a widespread radiations of crinoids, continued priliferation and expansion of the brachiopods and also the oldest known fossils of coral reefs.
Higher trophic level is further up the food chain. Further up you go there are less and less competitors. So the answer is true
The correct answer is: B) recognition of the prokaryotic promoter by RNA polymerase
The similarities between prokaryotic and eukaryotic transcription are that DNA is template used for the mRNA synthesis and that this is process is facilitated by the enzyme RNA polymerase.
One of the difference between this process in eukaryotes and in prokaryotes is the promoter region: eukaryotes contain TATA box and CAT box, while prokaryotes don’t (they have Pribnow box that is similar to the TATA box). Promoter region in prokaryotes is always upstream to the start site, while in eukaryotes it can be downstream.
