Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.
Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum
Answer:
The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.
Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

population sizes of three African animals in 1990 and in 2000.
Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.
Answer:
Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.
Explanation:
The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

What allows the three atoms in a water molecule to stay together
Answer:
Three types of bonds hold atoms together within molecules: ionic, covalent, and polar covalent. ... Hydrogen bonds allow two molecules to link together temporarily. • Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Thus, option A is correct.
What are covalent bonds?A covalent bond is the exchange of electrons between atoms. This type of bond occurs between two atoms of the same element or elements that are close to each other in the periodic table.
Strong linkages—called covalent bonds—hold together the hydrogen and oxygen atoms of individual H₂O molecules.
Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge.
Therefore, covalent bonds formed by shared electrons of hydrogen and oxygen atoms of individual H₂O molecules. Thus, covalent bond allows the three atoms in a water molecule to stay together. Thus, option A is correct.

Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data
Answer:
simple:
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.
Which option describes a strong argument against the development of nuclear power? A nuclear power company is proposing a nuclear power plant near a quiet, small waterside town. The company is promoting this development by stating that nuclear power does not produce pollutants.
Answer:
The correct answer is B) The company is promoting this development by stating that nuclear power does not produce pollutants.
Explanation:
Whilst the process of power generation itself does not produce environmental pollutants like fossil fuels which features the emission of carbon monoxide when they are partially combusted, it does leave behind radioactive wastes, in the same way, combusted charcoal or wood leaves ash behind.
The challenge with radioactive wastes is that they are inimical to human health and can remain so for hundreds of centuries.

How Clark Developed Seizures
The following list is not in the correct order. The first three events are numbered correctly. Drag and drop the
remaining events in the order that led to Clark's seizures.
picture above for the order.
Answer:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures
Explanation:
Seizures are defined as the common complication of drug intoxication.
As per the clinical observations for Clark , normal blood and matrix sodium concentration lose sodium ions due to diarrhea. As given too much water causes sodium levels to decrease. Due to lower sodium concentration, the free water move into the matrix and increased matrix pressure. This pressure causes the abnormal neuron firing rate to increase which causes seizures.
Hence, the correct order is:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures

Answer:
Form hypothesis: Where do you think trees get the nutrients they need to grow?
I think the trees get the nutrients from the soil and sunlight
Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer, bears, and mushrooms) are removed from the forest?
I think they will increase dramatically because there is nothing affecting them badly.
Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA tab. Was your prediction correct? Explain what you found.
Yes my hypothesis was correct without the other organisms affecting the trees growth the tree population increased.
Draw conclusions: Substances that contain carbon and are produced by living things are called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.
Do your results show you that trees are producers or consumers? Explain.
Trees are producers because they make it by using the sun's light.
Analyze: Click the FOREST tab. Click the plus (+) button for mushrooms several times. Click Advance year a few times. Select the DATA tab. How did adding mushrooms affect trees?
adding the mushrooms didn’t affect the trees.
Extend: The mushrooms thrived without hurting trees. How could this happen? Try for two possible explanations. Write your ideas in the space below.
The mushrooms are decomposers; they thrive off of dead things including the trees so they do not harm the trees at all.
Explanation:
The trees in the forest controls the flow of water on the land.
When heavy rainfall occurs the trees help in trapping the water in the soil which reduces the chances of flood. These trees also provide habitat as well as food for living organisms that lives in the forests.
The trees get the nutrients they need to grow from the soil with the help of their roots. Decomposers present in the soil feed on dead bodies which turn into nitrogenous substances that is used by the trees for making amino acids.
The tree population increases if all other organisms such deer, bears, and mushrooms are removed from the forest because these organisms feed on the trees so increase occur in the tree population.
