Glacial acetic acid, also known as concentrated acetic acid, is not a conductor because it does not contain any free ions or charged particles that can move and carry an electric charge.
In contrast, aqueous acetic acid is a conductor because it is dissolved in water, which is a polar solvent that can dissociate the acetic acid molecules into ions. In other words, when acetic acid dissolves in water, it breaks apart into positively charged hydrogen ions (H+) and negatively charged acetate ions (CH₃COO-), which can move and conduct electricity. Therefore, water is necessary for conductivity because it allows the acetic acid molecules to dissociate into ions and form a solution that can conduct an electric current.
Conduction is the transfer of heat energy between nearby atoms or molecules. Due to the tighter particle spacing in solids and liquids compared to gases, conduction happens more easily in these two phases.
Conduction is the process through which heat is transferred from an object's hotter end to its cooler end. The word "thermal conductivity" describes an object's ability to transport heat, and it is symbolised by the letter "k."

19.982
Answer:
18.58
Explanation:
From the question given above, the following data were:
Isotope A:
Abundance of A = 54%
Mass of A = 17.984 amu
Isotope B:
Abundance of B = 32%
Mass of B = 18.985 amu
Isotope C:
Abundance of C = 14%
Mass of C = 19.982 amu
Average atomic mass =?
AVERAGE = [(Mass of A × A%)/100)] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]
AVERAGE = [(17.984 × 54%)/100] + [(18.985 × 32%)/100] + [(19.982 × 14%)/100]

Why might an increase in the concentration of greenhouse gases be a concern? What
might be the effect of an increase? Use the diagram to help you answer.
Answer:
too many greenhouse gases can cause the temperature to increase out of control. ... The increased greenhouse effect is causing changes in our planet that can affect our lives. The major Greenhouse Gas, carbon dioxide, emitted naturally and by the burning of fossil fuels, stays in the atmosphere a long
Effects: By increasing the concentration of greenhouse gases in the atmosphere, we’re amplifying the planet’s natural greenhouse effect and turning up the dial on global warming.
The atmosphere of the Earth may begin to trap more and more heat if these greenhouse gases are present in excess. Earth warms as a result of this.
What are Greenhouse gases?A greenhouse gas is a gas that produces the greenhouse effect by both absorbing and emitting radiant energy at thermal wavelengths that are infrared. The five main greenhouse gases in the atmosphere of Earth are ozone, carbon dioxide, methane, and water vapour.
Carbon dioxide, methane, nitrous oxides, and water vapour are examples of greenhouse gases. (A "feedback" is the term used to describe water vapor, which reacts chemically or physically to changes in temperature.) Scientists have found that the warming effect of carbon dioxide contributes to the stabilisation of Earth's atmosphere.
Thus, the atmosphere of the Earth may begin to trap more and more heat if these greenhouse gases are present in excess. Earth warms as a result of this.

Answer:
Enteric Nervous System
The enteric nervous system (ENS) is a subdivision of the autonomic nervous system (ANS) that directly controls the gastrointestinal system.
LEARNING OBJECTIVES
Describe the structure and function of the enteric nervous system (ENS)
KEY TAKEAWAYS
Key Points
The enteric nervous system (ENS), which is embedded in the lining of the gastrointestinal system, can operate independently of the brain and the spinal cord.
The ENS consists of two plexuses, the submucosal and the myenteric. The myenteric plexus increases the tone of the gut and the velocity and intensity of contractions. The submucosal plexus is involved with local conditions and controls local secretion, absorption, and muscle movements.
While described as a second brain, the enteric nervous system normally communicates with the central nervous system (CNS) through the parasympathetic (via the vagus nerve ) and sympathetic (via the prevertebral ganglia) nervous systems, but can still function when the vagus nerve is severed.
The ENS includes efferent neurons, afferent neurons, and interneurons, all of which make the ENS capable of carrying reflexes and acting as an integrating center in the absence of CNS input.
The ENS contains support cells, which are similar to the astroglia of the brain, and a diffusion barrier around the capillaries surrounding the ganglia, which is similar to the blood –brain barrier of cerebral blood vessels.
Key Terms
enteric nervous system: A subdivision of the peripheral nervous system that directly controls the gastrointestinal system.
EXAMPLES
The second brain of the enteric nervous system is the reason we get butterflies in our stomach or need to use the restroom more frequently when we are nervous and/or under stress.
The gastrointestinal (GI) system has its own nervous system, the enteric nervous system (ENS). Neurogastroenterology is the study of the enteric nervous system, a subdivision of the autonomic nervous system (ANS) that directly controls the gastrointestinal system. The ENS is capable of autonomous functions such as the coordination of reflexes.
Although it receives considerable innervation from the autonomic nervous system, it can and does operate independently of the brain and the spinal cord. The ENS consists of some 100 million neurons, one-thousandth of the number of neurons in the brain, and about one-tenth the number of neurons in the spinal cord. The enteric nervous system is embedded in the lining of the gastrointestinal system.
Ganglia of the ENS
The neurons of the ENS are collected into two types of ganglia:
The myenteric (Auerbach’s) plexus, located between the inner and outer layers of the muscularis externa
The submucosal (Meissner’s) plexus, located in the submucosa
The Myenteric Plexus
The myenteric plexus is mainly organized as a longitudinal chains of neurons. When stimulated, this plexus increases the tone of the gut as well as the velocity and intensity of its contractions. This plexus is concerned with motility throughout the whole gut. Inhibition of the myenteric system helps to relax the sphincters —the muscular rings that control the flow of digested food or food waste.
The Submucosal Plexus
The submucosal plexus is more involved with local conditions and controls local secretion and absorption, as well as local muscle movements. The mucosa and epithelial tissue associated with the submucosal plexus have sensory nerve endings that feed signals to both layers of the enteric plexus. These tissues also send information back to the sympathetic pre-vertebral ganglia, the spinal cord, and the brain stem.
This is an illustration of neural control of the gut wall by the autonomic nervous system and the enteric nervous system. A sensory neuron is shown to stimulate the nerves in the submucosal and myenteric plexuses, which are connected to nerves in the sympathetic and parasympathetic nervous systems. The sensory neuron is also shown signal the ganglia and central nervous system.
Neural control of the gut: An illustration of neural control of the gut wall by the autonomic nervous system and the enteric nervous system.
Function and Structure of the ENS
The enteric nervous system has been described as a second brain. There are several reasons for this. For instance, the enteric nervous system can operate autonomously. It normally communicates with the central nervous system (CNS) through the parasympathetic (e.g., via the vagus nerve) and sympathetic (e.g., via the prevertebral ganglia) nervous systems. However, vertebrate studies show that when the vagus nerve is severed, the enteric nervous system continues to function.
