All systems are dependent of each other. For example, the Digestive system shut down the body wouldn't get the energy required so the whole body would shut down. If the circlatory system shut down, the body wouldn't get oxygenated blood to the body so again, everything would shut down. If the respiratory system shut down, oxygen couldn't be taken into the blood and you guessed it, the body would shut down. If the Immune system shut down, simple illnesses like the cold or fever who be very dangorous to the body's health. Lastly, if the excretory system shut down, there would be no why to get the waste from the body out.
Hope this helped ( Sorry I couldn't answer the last question, I didn't have time )
Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.
The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.

<span>The organism will produce 12 chromosomes (A).
Sex cells are the products of meiosis. Daughter cells of meiosis contain half the number of chromosomes of the parent cell. So if the parent cell has 24 chromosomes, then the sex cell would have <em>12 chromosomes</em>.</span>
I think the answer is NUCLEUS.
Hope it helps!
