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.

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.

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.

Look closely at those leaf samples and devise a dichotomous key that helps you identify them. Be sure that your dichotomous key contains only pairs of statements about a single characteristic. For example, a pair of statements might be: A.leaf margin smooth B.leaf margin toothed However, you should avoid pairs of statements that do not address the same characteristic. The following pair, for example, would not be very informative in your key: A.leaf margin smooth B.leaf type needle-like As you develop your key, test it out with the 10 leaves provided on the Common Leaves sheet. When you've developed a key that identifies all 10 leaves, type your statements, “go tos,” and identifications, following the format in the example below. The example is based on this lesson’s dichotomous key for birds. Statement Types/Dichotomous key for birds Identification Name/Number of Leaves Statement 2a The bird has a crest of feathers on the top of its head. go to statement or identify bird blue jay Statement 2b The bird has a smooth head. go to statement or identify bird 3 Once you have completed your dichotomous key, answer the two remaining questions.

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?

Which would least likely have an impact on global climate changes?

What is the main purpose of the seeds in plants that have them?
