Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.

Answer:
The skeleton is subdivided into two major divisions—the axial and appendicular.
Explanation:
The axial skeleton forms the vertical, central axis of the body and includes all bones of the head, neck, chest, and back.
Answer: Histones and DNA have opposite charges -True
Acetylation of histones cancels their positive charge- True
Acetylated histones are more attracted to DNA - False
Acetylation creates binding sites for remodeling engines and other factors- True
Explanation:
It is widely found that acetylation of lysines leads to transcriptional activation. The modifications of histones such as acetylation affect the affinity of the histone for interacting proteins that control the transcriptional activity of chromatin,
which has led to the concept of a histone code.The positive charge on the histones is removed by acetylation, hence they decrease the interaction of histones with the negatively charged phosphate groups of DNA. As a result, the highly condensed chromatin is now transformed to a more relaxed structure and thereby higher level of transcription are achieved
