Answer:
The correct answers are "The DNA in a nucleosome is wound around eight histone proteins", "Between nucleosomes is a stretch of DNA called "linker DNA", "H1 seals off where DNA enters and leaves the nucleosome", "Nucleosomes contribute to DNA packing", and "Histones have tails that stick out and can be modified, affecting DNA expression".
Explanation:
Nucleosomes are comprised of DNA and histones that in conjunction form structural units of the chromosomes. The DNA in a nucleosome is wound around eight histone proteins, which are known as the histone octamer. Between nucleosomes is a stretch of DNA called "linker DNA", which is an unwrapped DNA that can be between 10 to 50 base pairs long. H1, one of the four types of histone, seals off where DNA enters and leaves the nucleosome serving as an anchor to the complex. Nucleosomes contribute to DNA packing by wrapping the DNA and forming the structural units of the chromosomes. Histones have tails that stick out and can be modified, affecting DNA expression; which are known as "histone tails" located in the N-terminal side and where higher order structures are arranged.
Answer:
Lipids
Explanation:
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane.
Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.
<h3 /><h3>What is the Hypothesis?</h3>
Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

Answer:
true
This is the major advantage to passive immunity; protection is immediate, whereas active immunity takes time (usually several weeks) to develop.
hope this helps:))
<h2>Ethical Principle of Autonomy</h2>
Explanation:
- Autonomy reflects the major right of all people for self-determination, to make on freely settle on decisions. Autonomy is reflected by the customer's statement to stop taking the prescription
- The nurse's encouraging the customer to keep on utilizing the prescription on account of the drug's advantages mirrors the guideline of value, that is, the medical caretaker is utilizing logical information and fusing that information to advance the customer's greatest wellbeing potential
- Right now, a drug would assist with controlling the customer's burdensome side effects. Equity mirrors the obligation to treat all reasonably; paternalism is the conviction that information and training approve experts to settle on choices to benefit the customer
