<span>Fluoride is the element that is added to city water supplies and toothpastes to prevent tooth decay. According to research, fluoride helps to prevent tooth decay as it can reduce cavities by 24% and by boosting the production of saliva. Saliva helps to protect the tooth enamel by providing high levels of calcium and phosphate ions to the surface of the tooth.</span>
Answer:
Process B : constant pressure condition
Process A : constant volume condition
Explanation:
In case of constant pressure, some of the energy is used to do work on the surrounding to keep pressure constant. Due to this, the total heat energy is less than in case of constant volume. In Case of constant Volume all of heat is available, produced in reaction because no work is done.
If we look at our data,we will find that process B has energy 23.3 KJ which is less than process A, the energy of which is 25.9 KJ. It means Process B is occurred at constant pressure condition and Process A has occurred at constant volume condition
Invasive species can do all sorts of damage to an existing ecosystem, including changing habitats and starving native animals of food and resources.
<h3>What is an invasive species?</h3>
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitats for native wildlife.
