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

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
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 extinctionBackground 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.

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?
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.
