Cladogram shows that Osteichthyes should be under group A. Going back to their characteristics, they’re a group of fish that have the derived characteristics of jaws and true bones. So, moving backwards from group A these derived characteristics are clearly traceable, wherein each line is showing a relationship/connection.
Answer:
(A) Both organisms would grow equally well.
Explanation:
General purpose media is a culture medium that allows the growth of any kind of organism. Generally this type of culture medium is used to analyze the biochemical properties of microorganisms, facilitating their identification.
Selective media plate, on the other hand, is used to select the species to be isolated and to prevent the growth of microorganisms that are not needed. For this reason, in this type of culture medium only one species of microorganism would grow well.
Finally, a differential media plate promotes a change in the color of bacterial colonies, making it possible to distinguish various genera and species of microorganisms, so that the two microorganisms would not grow equal.
As the general purpose media allows the growth of any kind of organism equally, it would be easy to identify which petri dish would be with this culture medium. Plaque with the general purpose media would allow both organisms to grow equally well.
Answer:
B, they share similar chemical properties.
Explanation:
The Cenozoic era is the most recent era which still lasts. It is the era about which the scientist have by far the most knowledge. The reason why this era is much better studied and known by the scientists is exactly that it is the most recent one. The fossils are there in abundance as they did not had enough time to totally dissolve. The rock layers formed in this period are largely kept, and very little of them have been destroyed. The continents have moved of course, but it is easily traceable and in much lesser extent when compared with longer periods of time. The events that happened in this era are much recent, so their leftovers are abundant, as well as easier to study and find. All of this have resulted in much larger database, and significantly greater knowledge about this era than any other before it.
