H+
OH-
nitrogen
OH- is common to bases.
Explanation:
The base is a is an ionic compounds which when placed in aqueous solution dissociates in to a cation and an anion OH-.
The presence of OH- in the solution shows that the solution is basic or alkaline.
From Bronsted and Lowry concept base is a molecule that accepts a proton for example in NaOH, Na is a proton donor and OH is the proton acceptor.
A base accepts hydrogen ion and the concentration of OH is always higher in base.
There is a presence of conjugate acid and conjugate base in the Bronsted and Lowry acid and base.
Conjugate acid is one which is formed when a base gained a proton.
Conjugate base is one which is formed when an acid looses a proton.
And from the Arrhenius base Theory, the base is one that dissociates in to water as OH-.
Answer:
metal and OH-
Explanation:
omnivore
B.
decomposer
C.
producer
D.
herbivore
The term describes the role of fungi in this food chain is decomposer. Therefore, option B is correct.
In forest, fungi are known as the important decomposers. Some kinds of fungi, such as mushrooms, look like plants. But fungi do not have chlorophyll, it is the pigment that green plants use to make their own food with the help of sunlight.
Fungi have the ability to convert nutrients so that they are available to plants. Some fungi are decomposers, which means they decompose plant and animal waste, cycling nutrients and increasing their availability in the soil.
Decomposers like fungi and bacteria are complete the food chain. They turn organic wastes that are decaying plants into the inorganic materials, such as nutrient-rich soil.
Thus, option B is correct.

Mixtures and solutions are alike in that they both involve combining two or more substances, but they have some differences. In a mixture, the substances are physically combined and can be separated using physical methods, while a solution forms a homogenous mixture that cannot be easily separated.
Mixtures and solutions are alike in that they both involve combining two or more substances. However, there are some differences between the two. In a mixture, the substances are physically combined and can be separated using physical methods, such as filtration or evaporation. In a solution, one substance is dissolved in another, forming a homogenous mixture that cannot be easily separated.
For example, mixing salt and water creates a solution, where the salt particles are uniformly dispersed in the water. On the other hand, combining sand and water creates a mixture, where the sand particles can be seen and separated from the water.

Answer:
D. chemical bonding
Explanation:
Atoms are joined to form compounds by ionic bonds (formed when one or more electrons are transferred from one atom to another) or covalent bonds (formed when atoms share electrons instead of transferring them). The ionic bonds and covalent bonds are both different types of chemical bonds.
