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.

Can you help with number 5? I didn’t feel like writing it.
Leno4ka [110]

From what I can see in the picture, the cell appears that it would take up half of the microscopes view if it were to be pushed to the very edge on one side.

That would be the radius. The radius is half of the diameter, and half of 0.8 mm would be 0.4 mm. The length of the cell is about 0.4 mm.

Now for the width. Since the diameter of the FoV (field of view) is 0.8, we can see that the cell doesn't reach both sides of the circle it is in. It also doesn't appear to take up half of it. So, to get the aprox. width of the cell, we're going to half the radius.

Half of 0.4 mm is 0.2 mm, so the width of your cell is about 0.2 mm.
