Wetlands are areas where water covers the soil. Swamps, marshes, and other wetland areas help to control flooding because they naturally hold water. Wetland regeneration is a recent trend in conservation. In some areas, land previously used for farming is being converted into wetlands.

Research wetlands, the types of organisms that live there, and examples of wetland restoration and regeneration. Then answer these questions:

What factors do scientists need to consider before turning farmland into wetlands?
How could wetland restoration affect humans who live in the area? How might it affect native wildlife? (Consider both positive and negative consequences.)
If you were planning a wetland regeneration project, how would you monitor its success?

Answers

Answer:

There are plenty of animals that live in wetlands, such as lizards, turtles, snakes, newts, Alligators, Invertebrates, and along with sea life. Scientists need to consider taking farmland and constructing it into a wetland; they would need to consider the influx and the outflow of the groundwater levels and the duration of ground saturation. Wetlands can have both positive and negative effects on humans. Some negative side to wetlands is how to release of chemicals coming from swamps could affect the environment for people. Also, how fast pollution could arise from these released chemicals. Waterlands could also change the water quality, quantity, and flow. Although there are negative points, we do have positive ones as well; This includes how the wetlands will be protecting endangered species and how it will clean the lakes and seas. The water quality, quantity, and flow also could increase instead of decrease. If I was to make a wetland regeneration project, I would monitor its success by making charts on what increased positively like the native plants and the nest platforms.

Explanation:

100% on it

Answer:

Hope this helps.

Explanation:

1.Elements of site hydrology that are important to maintaining a wetland are inflows and outflows of ground water and surface water, the resulting water levels, and the timing and duration of soil saturation or flooding.

2. In addition to supporting food and other resources for local people, restored mangroves effectively recycle nutrients, provide wildlife with habitat, and protect coasts from storms, erosion, and sea level rise

3.Appropriate metrics to evaluate success in achieving this goal include number of native plant species present, presence and density of invasive plant species, coverage of wetland habitat, hydrological measurements, and surveys for selected wildlife species of interest.

7. An example of artificial selection is:
•After a large population is destroyed, a smaller population repopulates the species.
•A small group if individuals breaks off from a larger population to relocate.
•Women with wider hips due to caesarian section births.
•Women with more narrow hips due to caesarian section births.

Which of the following has the most potential of experiencing background extinction based on the natural disruption described?

A population observing a natural volcano erupting on a remote island every year
A population that lost their habitat due to a hurricane lasting several hours
A species that will not grow during a specific season every year
A species that struggles to compete for resources due to limited access from habitat loss

Answers

The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year

What is Background extinction

Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.

A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.

Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is :  A species that will not grow during a specific season every year.

1.Consider the four demographic characteristics relating to biotic potential
listed in the text: (1) usual number of offspring per reproduction, (2) chances
of survival until age of reproduction, (3) how often each individual
reproduces, and (4) age at which reproduction begins. Relate each factor to
the human population, rating each one as contributing to a high or low biotic
potential, justifying each rating. Then decide overall if humans have a high or low biotic potential
low biotic potential.

Answers

Based on the four demographic characteristics relating to biotic potential, humans generally have a low biotic potential.

What is biotic potential?

Biotic potential refers to the maximum reproductive capacity or potential of an organism under optimum environmental conditions.

The demographic characteristics relating to biotic potential are:

usual number of offspring per reproduction- it contributes to low biotic potential because humans usually produce one offspring per reproduction chancesof survival until age of reproduction - contributes to high biotic potential since humans have high chances of survivalhow often each individual reproduces - contributes to low biotic potential since humans have usually reproduce at least once every nine months age at which reproduction begins - contributes to a low biotic potential since humans begin to reproduce at a later age of at least 12.

Therefore, humans generally have a low biotic potential.

Sound waves are produced when something is caused to reflect. vibrate. slow down. get warmer.

Answers

Answer:

B) Vibrate

Sound is created through vibration.

Sound waves are produced when something is caused to vibrate. When an object vibrates, it creates a disturbance in the surrounding air molecules, causing them to bump into each other and create a wave of pressure fluctuations. Hence option B is correct.

What are sound waves?

Sound waves are a type of mechanical wave that transfers energy through oscillations of particles in a medium such as air, water, or solid material.

When an object vibrates or moves, it sets off a series of pressure waves in the medium around it, creating a disturbance that travels through the medium as sound.

The sound wave consists of compressions and rarefactions of the medium, where compressions are areas of high pressure and rarefactions are areas of low pressure.

The frequency of the vibration determines the pitch of the sound wave. For example, a higher frequency of vibration produces a higher-pitched sound, while a lower frequency produces a lower-pitched sound. The intensity of the vibration determines the volume or loudness of the sound wave.

Hence option B, vibrate is correct.

Identify how the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes.

Answers

The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

What is the relationship between histones and DNA?

Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.

How does DNA compact with histones?

Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.

Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

What occurs during the link reaction in cellular respiration?

Answers

Answer:

Produce an acetyl group.

Explanation:

The Link Reaction happens in Mitochondria. Mitochondria in cells take up the pyruvate which is formed from glycolysis in the cytoplasm. Once the pyruvate is in the mitochondrion, enzymes within the matrix of the mitochondrion remove hydrogen and carbon dioxide from the pyruvate. This is called oxidation (removal of hydrogen or addition of oxygen) and decarboxylation (removal of carbon dioxide). Therefore, the process is called oxidative decarboxylation. The hydrogen removed is accepted by NAD+. The link reaction results in the formation of an acetyl group. This acetyl group is then accepted by CoA and forms acetyl CoA.
