<span>The electromagnetic energy released during fusion is converted to other kinds of photons as it is transferred through which layer of the Sun? It is in the radiative zone</span>
<span> Very inefficient. Almost 90% of all energy is lost between trophic levels. That is why larger animals need to eat more, because less energy is being consumed.

Answer: a star expels most of its outer material until only the hot core remains, which then settles down to become a young a white dwarf
Explanation:
Answer:
The correct answer is option b. "20 H1, 40 H2A".
Explanation:
Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.
