What is gingivitis?Gum inflammation is brought on by gingivitis, a non-destructive condition. Plaque-induced gingivitis, which results from bacterial biofilms (also known as plaque) that are attached to tooth surfaces, is the most prevalent type of gingivitis and the most prevalent type of periodontal disease overall. Plaque causes the majority of kinds of gingivitis.
While some occurrences of gingivitis never turn into periodontitis, gingivitis is always the first stage of periodontitis. Gingivitis is treatable with excellent oral care, but if left untreated, it can proceed to periodontitis, in which the gum inflammation causes tissue loss and bone loss surrounding the teeth.

Which immunologic change should the health care provider consider when planning care for an individual with chronic stress?
The immunologic change that the health care provider consider when planning care for an individual with chronic stress is to look for the cortisol levels that reduces the immune response.
Chronic stress is the feeling of anxiety and stress for a long period of time. The symptoms include ache, pain, insomnia, less socialization, and unfocused thinking.
Treatment involves visiting psychologist or psychiatrist, medication, lifestyle changes, etc.
The cortisol level increases in the blood due to chronic stress which suppresses the inflammatory responses and reduces the body's natural capability of immune responses.

1. how are positive ions formed (what is gained or lost)? use potassium (k) as an example. how many protons and electrons does a neutral atom of potassium (k) have? how many protons and electrons does a positive ion of potassium (k) have?
Positive ions are formed when electrons are lost, for example, Potassium ion, K⁺ is formed when a Potassium atom, K losses one electron. A neutral atom of Potassium (K) has 19 protons and 19 electrons, and a positive ion of Potassium (K⁺) has 19 protons and 18 electrons.
Ions are charged particles formed when neutral atoms loss or gain electrons. When electrons are lost, positively charged particles called cations are formed, and when electrons are gained, negatively charged particles called anions are formed. Electropositive elements are more likely to form cations. Potassium (K) losses one electron in order to obtain a stable configuration, forming Potassium ion (K⁺).
For all neutral atoms, the number of protons is always equal to the number of electrons. The number of protons is the same as the atomic number. Potassium (K) has an atomic number of 19, thus it has 19 protons. Since Potassium (K) atom is a neutral atom, it will also have 19 electrons.
However, Potassium ion (K⁺) has lost one of its electrons, so it will have 18 electrons instead of 19. Therefore, Potassium (K) has 19 protons and 19 electrons, while Potassium ion (K⁺) has 19 protons and 18 electrons.

Genes dictate the types and amounts of nutrients in food that will be transformed and reassembled into body structures and compounds.
Gene expression is induced by genes and thus alters the phenotype of an individual. In the converse single nucleotide polymorphisms taking place in a range of genes that are important in inflammation as well as the metabolism of lipids tend to alter the biological activity of important pathways of metabolism and mediators that influence nutrient ability to interact with them.
The genotype or allele set of genes is a unique combination of genes or genetic makeup of a particular individual.

An action potential is generated by the movement of:_______
a. glial cells.
b. hormones.
c. vesicles.
d. ions.
An action potential is generated by the movement of positive ions
Action potentials are short electrical signals that neurons use to interact with one another. The movement of certain ions into and out of the neuron causes these fleeting changes in the voltage across the membrane. The membrane is primarily permeable to K+ when the body is at rest, which causes the membrane potential to form. In response to depolarization, an action potential starts at the axon hillock. An electrical stimulus causes voltage-gated sodium ion channels to open during depolarization. The positive charge of the sodium ions causes them to rush back into the cell, shifting the potential there from negative to more positive. An action potential is generated when a threshold potential is met. Only once a threshold has been met will action potentials happen.
Following depolarization, voltage-gated sodium ion channels start to shut. Voltage-gated potassium channels open as a result of the positive potential inside the cell, and K+ ions then exit the cell via their electrochemical gradient. The membrane potential shifts more negatively and begins to get closer to the resting potential as the K+ leaves the cell.

Water is a polar molecule that exhibits the properties of adhesion and cohesion. identify the examples as either cohesion, adhesion, or both.
Water is a polar molecule and exhibits both properties of adhesion and cohesion.
Water molecules possess strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesion is the scientific term for molecules' affinity towards other molecules of their sort. Surface tension, a phenomenon that causes a liquid's surface to have a tendency to resist rupturing when subjected to tension or stress, is caused by cohesive forces. Adhesion, which is the attraction of molecules of one kind to molecules of another kind, can be exceedingly powerful for water, especially when those other molecules have positive or negative charges. For instance, adhesion enables water to ascend through minute capillary tubes submerged in liquid. The capillary activity that causes this upward movement against gravity depends on interactions between water molecules (cohesion) also on the attraction of water molecules to the tube's glass walls (adhesion). We can infer from the surface tension and capillary action phenomena that water demonstrates both cohesion and adhesion qualities.

c. excessive carbohydrate breakdown
d. all of the choices are correct.
Ketone bodies are produced due to excessive fat breakdown.
The liver produces ketones, also known as ketones, as part of gluconeogenesis, a process that produces glucose during fasting and starvation. The liver creates three different ketone bodies. They are acetoacetate, beta-hydroxybutyrate, and acetone. When blood glucose levels are low, as they are when fasting, the liver cells' mitochondria, which are where ketone bodies are mostly formed, can start to synthesize ketone bodies. They are produced in the liver as a result of lipid metabolism.
When the body's needs for fuel are not met by the availability of sugar or glucose, ketones are produced. This happens while dieting or fasting and overnight. While glucagon and epinephrine levels are largely normal at these times, insulin levels are low.

Answer:
Evolutionary evidence suggests fungi evolved from protists that also gave rise to the fourth and most diverse group of eukaryotes: the animals.
Explanation:
The other three forms of eukaryotes, including fungi, descended from protists. The differences between these two groups of eukaryotes end there. As eukaryotic creatures, fungi are unable to produce their own nutrition and therefore do not "eat." Their nutrition must be absorbed, typically from decomposing organisms. Most plants and fungi are descended from aquatic protists around 1.1 billion years or so ago. Many protists use gametes to reproduce sexually, whereas others use binary fission to reproduce asexually. Several protists are important parasites of other organisms, including animals, and plants, as well as other protists.
