Therefore "the copperheads are subspecies and the cottonmouth is a separate species".
<u>Answer:</u> Option C
<u>Explanation:</u>
The higher classification is "copperhead" for both the subspecies Agkistrodon contortrix contortrix and Agkistrodon contortrix mokasen. As the name itself consist species name "A. contortrix", both are belonging from "Viperidae" family, "Crotalinae" subfamily and venomous pit viper subspecies.
These are generally silent snakes as they show lazy and motionless behavior when encountered but on agitating sufficiently they become protectively aggressive and they are species of eastern North America. While Agkistrodon piscivorous are separate species with higher classification as "Cottonmouth" and name carry species name "A. piscivorus". It is indigenous to southeastern United States and belongs to same family as copperhead.
Answer:
There are many shreds of evidence that support the theory of plate tectonics and make it such a firmly believed idea. These pieces of evidence include fossils, glaciers, earthquakes and volcanic activity, the shape of continents, the magnetism of rocks on the seafloor, the mid-ocean ridge system, and others.
Fossils give an idea of the location of the plants and animals that once existed. Earthquakes and volcanic activity also help in determining the cause of the boundaries and rifts formed. The shape of the continents seems to be fit with one other that gives the idea that these were together and moved away from each other.
<span>A pattern of inheritance responsible for a wide range of phenotypes that result from individual organisms having many different gene pairs controlling a single trait is b. polygenic traits. A polygenic trait is a pattern of inheritance where a single trait is influenced by many genes. Some examples of this pattern of inheritance are human skin color, height, and weight.</span>
Establishing just one tree species can impair soil fertility and prevent other species from being established.
We can arrive at this answer because:
- Ecological succession is the term that refers to the establishment and development of plant species in areas that were devastated until that area presents a large vegetative population when it reaches climax.
- During the establishment of ecological succession, the must be a great diversity of plants, allowing for harmony and balance between the species and the environment.
- When ecological succession is done with only one species, this balance is impaired, as well as ecological succession.
This is because a single tree species can hide soil fertility and make it unsuitable for planting any other species. In addition, the genetic unity among plants makes it easier to develop pests and diseases that can devastate the region.
