<u>Answer:</u>
The type of change that was responsible was “histone acetylation or DNA methylation”.
<u>Explanation:</u>
- Histone acetylation is the process that involves the epigenetic adjustments that functions in the transcription process while regulating DNA.
- Histone acetylation or DNA methylation is the major component of the gene regulation while passing from one generation to another.
- The Acetyl groups are hooked up to lysine’s in histone tails so their charges play a vital role to avoid the histone tail to bind with the other molecules.

Explanation:
The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.
On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.

Explanation:
Living things are made of four types of molecules, known as macromolecules. These macromolecules are proteins, nucleic acids (DNA and RNA), lipids (fats) and carbohydrates. Each type of macromolecule is made of its own building blocks, which are intricately connected to form different shapes.
