Answer:
Power is measured at three different levels pertinent to flapping flight. The first level is metabolic power input (P met) to the muscles, directly of interest to a flying, foraging bird, and generally a realm of study for respiratory, thermal and chemical physiologists.P met is the rate the bird expends chemical energy to supply the flight muscles, and it may be measured using double-labeled ...
Answer:
According to scientists in some countries, the latest DNA research located the red panda in its own independent family, the ailurids (Ailuridae). Ailurids are themselves part of the large superfamily Musteloidea, which also includes the Mephitidae, Mustelidae and Procyonidae families, but, unlike the giant panda, it is not a bear (Ursidae).
The taxonomic classification of red panda and giant panda has been the subject of debate for many decades, as it has characteristics of both bears and raccoons. However, they are only distantly linked by a common ancestor of the first Tertiary period. Its common ancestor dates back tens of millions of years, with a wide distribution in Eurasia.
Explanation:
Musteloids (Musteloidea) are a carnivorous mammalian superfamily united by distributed characters of the skull and teeth. Musteloids share a common ancestor with pinnipeds, specifically phocids, the family to which seals belong.
Musteloids consist of the families Ailuridae (red pandas), Mustelidae (mustelids: weasels), Procyonidae (protionids: raccoons and relatives) and Mephitidae (skunks).
In North America, the ursoids and musteloids appear first in the Chadronian (Upper Eocene). In Europe, ursoids and musteloids first appear in the lower Oligocene immediately following the great Stehlin break.
The Musteloidea superfamily may not be a monophyletic group. Some or all of the diagnostic characters may have evolved into two or more independent radiations from primitive ursoids such as Amphicynodon.
Answer:
B. Virus.
Explanation:
Hello.
In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.
Best regards.
Political science is a social science discipline that deals with systems of government and the analysis of political activity and political behavior. It deals extensively with the theory and practice of politics which is commonly thought of as the determining of the distribution of power and resources.
