Habitat restoration

Explanation:

It will have a negative effect

The factor that would have a negative impact on the organisms that live in the salt marsh is option d, where an invasive species outcompetes native species for resources.

When an invasive species enters a salt marsh ecosystem, it often lacks natural predators and can rapidly reproduce, outcompeting native species for vital resources such as food, space, and shelter. This competition can disrupt the balance of the ecosystem and negatively impact the native species that are adapted to the specific conditions of the salt marsh.

Invasive species often have aggressive feeding habits, consume native species as prey, or outcompete them for limited resources, leading to a decline in the population size or even the extinction of native species. This disruption can have cascading effects on the entire ecosystem, affecting trophic interactions and nutrient cycling.

Salt marshes are complex habitats with specific ecological niches, and native species have evolved to rely on the availability of certain resources and interactions with other species. The introduction of an invasive species can disrupt these intricate relationships and upset the ecological equilibrium.

Therefore, the presence of an invasive species outcompeting native species for resources in a salt marsh would have a negative impact on the organisms residing there, leading to a loss of biodiversity and potential ecological imbalances. Therefore the correct option is d

Hydrolysis

Explanation:

Hydrolysis is a reaction that needs water to breakdown macromolecules into simpler units.

Macromolecules are giant polymers made up of several repeating monomeric units.

Answer:

O A. Mites are the sole cause of colony collapse disorder.

Answer:

When this happens, sometimes the cell commits a special type death is called apoptosis. Apoptosis, otherwise known as programmed cell death, ensures that if mitosis goes wrong and cannot be fixed, the cell does not continue to divide, as this would lead to the production of mutant cells that might cause problems.

The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).

The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.

In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.

Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.

The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.

Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.

Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.

Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

Answer: The correct answer is the letter a. Water into root hair cells.

Explanation:

Osmosis refers to the net movement of water molecules across a partially permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

The energy is related to the change of state represented by the model by: D. Atoms lose energy as a gas changes to a liquid.

A model of the transition from a gas to a liquid is shown in the accompanying image. It demonstrates how atoms or molecules change from being widely scattered as in a gas to being concentrated as in a liquid.

The atoms in this process move from a higher-energy state  to a lower-energy state releasing or losing energy in the process. The most common kind of energy loss is heat.

On June 18th, 1858, Charles Darwin obtained an essay written by way of Alfred Russell Wallace from Ternate in the Malay Archipelago. It outlined Wallace's theory of evolution by herbal determination in terms that had been strikingly comparable to Darwin's very own drafts of the theory.

Wallace knew Darwin was working on comparable research. In 1858, he despatched Darwin a letter outlining his thoughts about evolution. The two collaborated on a scientific paper, discussing their proof for herbal resolution and evolution.

Answer: B

Explanation:

Answer:

No, because it would lead to chromosome mosaicism  

Explanation:

Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.

Answer:A, C, D

Explanation:

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.

Temperature is a unit used to convey hotness or coldness on any of a number of measures, including Fahrenheit and Celsius.

The physical concept of temperature conveys in numerical form how heated or chilly something is. A thermometer is used to determine temperature.

Thermometers are calibrated using a variety of temperature scales, which traditionally defined different reference points and thermometric substances. The most popular scales are the Celsius scale, also known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), and the Kelvin scale (K), with the latter being primarily used for research reasons.
