Answer: D

Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.

A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.

D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.

I hope this helps. Have a great week!

The majority of the cell membrane is composed of what type of lipids?

mixas84 [53]

Answer:

The majority of the cell membrane is composed of PHOSPHOLIPIDS.

Explanation:

Phospholipids are a type of lipid that is found in the cell membrane of cells. This type of lipid are a good fit for cell membrane because they have the capacity to form bi layers. The lipids are divided into tail and head regions; the head is hydrophilic in nature while the tail is hydrophobic in nature. The hyrophilic head is made up of phosphate group while the hydrophobic tail is made up of fatty acid molecules.

Find an example of an exotic species that has beenintroduced in an

GREYUIT [131]

Answer:

Introduction on Argentinian Red And, Solenopsis invicta, in the United States.

Explanation:

A species is considered to be introduced when it has been released intentionally or accidentally in a new place or area, out of its natural geographical distribution range, during historical times.

The, Argentinian Red Ant, Solenopsis invicta was introduced by accident in the United States in the 1930 year when some commercial ship coming from Brazil unloaded infested merchandise. Since that date, it has been colonizing several areas, expanding in a range of 30 to 50 kilometers per year. Nowadays it is occupying more than 110 million hectares, causing several problems:

Biological problems: It is a very aggressive species that can affect animals and plants. In Texas, the invertebrates' biodiversity decreased by 40% and the local ants decreased by 70%. Their nests' building affects the roots of plants causing important harvest losses.

Economical problems: The United States government has expended more than 250 million dollars trying to solve the problem, while the yearly losses exceed 1,000 dollars. The harvest losses have causes an important decrease in production.

Sanitary problems: These ants might be considered dangerous as they have attacked people and animals. Texas invests 750,000 dollars a year to treat wounds in cattle and other affected animals.

There are some steps to prevent and reduce biological invasions, such as introduction prevention, eradication when it is still possible, contention to avoid the species expansion, expansion control (biological, mechanical, chemical), and restoration of the affected areas.

In the case of the Red Ant it would have been very important to control the state of the merchandise coming from Brazil to avoid the ant's introduction and its posterior spread. It also would have been important to deal harder with the problem when it was recently to avoid the ants' expansion by educating the people about invasive species and how to react about it, and by applying some eradication actions when it was possible. Nowadays the species is under control, but they can not completely eradicate it.
