Detergents, fertilizers, and raw sewage that make their way into rivers, lakes, and underground aquifers are sources of pollution for humans but can be nutritional for some marine life.
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:
We use pH as a measurement of how acidic something is. pH scale is what we use to determine how acidic it is. i tried hope it helps:)
Explanation:
Produce antibodies against anything with a RH positive, or different blood type. Which when the antibodies attack to different blood can cause blood clots, which could be fatal.
A. Nutrients and other materials pass through the cell membrane through the process of diffusion. This allows the cell to perform all the activities it requires for daily maintenance and living. The concentration gradient allows the cell to regulate just how much of a certain material passes through it.
