Inside a water molecule, hydrogen and oxygen are connected by polar covalent bonds. This results from oxygen's higher electronegativity, causing the shared electrons to spend more time near the oxygen atom, creating a polarity. Hydrogen bonds, although not found within single water molecules, exist between different water molecules and contribute to water's overall properties.
The bonds found inside a water molecule between hydrogen and oxygen are polar covalent bonds. A covalent bond is established when electrons are shared between atoms. In a water molecule (H2O), electrons are shared between hydrogen and oxygen. However, oxygen has a greater electronegativity than hydrogen, causing the shared electrons to spend more time closer to the oxygen atom, hence creating a polarity.
Sometimes, a weaker bond known as a hydrogen bond, which is a type of dipole-dipole interaction, can be found between water molecules. Although these are not found inside a single water molecule, they are crucial for the properties of water as a whole.

Answer:
niche
Explanation:
The answer is the Sympathetic nervous system as a Group of answer choices central endocrine sympathetic somatic parasympathetic shows these symptoms.
The sympathetic nervous system is a part of the self-sustaining fearful device which controls the involuntary frame capabilities such as coronary heart rate, breath rate, perspiration, etc. The sympathetic is in particular answerable for the boom withinside the feature of frame capabilities while the frame perceives a risk. When confronted with a risk or distress, the sympathetic nervous system initiates physiological reactions called the “combat or flight” response, thereby growing the frame’s alertness to such risk. Examples of improved frame capabilities or “combat or flight response” consist of improved perspiration and improved coronary heart rate, as exhibited via way of means of Blair.
The sympathetic nervous system directs the body's speedy involuntary reaction to risky or disturbing situations. A flash flood of hormones boosts the body's alertness and system coronary heart rate, sending greater blood to the muscles.
Hence conclude the sympathetic nervous system is the answer.

Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.
