Scientists once debated how to classify the red panda. Today, how has analysis of the genome of the red panda provided evidence
skad [1K]

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.

Look up viruses. Write a short summary of what they are and what they do.
vlabodo [156]

Answer:

Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.

How are cancer cells able to get nutrients away from your healthy cells?
chubhunter [2.5K]
<span>well this is an interesting question and i would say it may depend on what type of cancer cells you are growing and what type of "normal" cells your growing. One possibility is that cell fusion events may occur between your cancer cells and normal cells, thus creating a few options 1 - making the normal cell cancerous, 2 - making the cancer cell that fused with the normal cell not cancerous anymore. 3 - either way the fused cell will have a different genotype and hence be a different cell.</span>
