It is called subscript indicating the number of atoms.
Explanation:
The chemical compound is formed by two or more elements.
The compound is formed by the sharing, accepting or donating the electrons.
The compound formed by two elements will have different valencies of cations and anions.
In chemical formula of compound specific number of atoms of each element are present.
eg: H2O (2 atoms of hydrogen bonded with one atom of oxygen)
NaCl (1 atom of sodium and one atom of chloriine are bonded.)
NaHCO3 ( 1 atom of sodium, 1 atom of hydrogen, 1 atom of carbon and 3 atoms of oxygen.)
Answer:this is definitely a covalent bond

Answer:
Mutualism
Explanation:
Organisms in an ecosystem interact with one another from time to time. The close interaction between two organisms is referred to as SYMBIOSIS. Symbiosis is of different types depending on the how it affects the involved organisms. The example in this question depicts MUTUALISM.
Mutualism is the type of symbiotic relationship between two organisms in which both organisms benefit from the relationship. This is the case of the LICHEN, which involves the Algae and Fungi. The algae benefits by making use of the water and minerals supplied by the fungi while the fungi benefits by using the food the algae produces via photosynthesis.
Lactic fermentation occurs in many organisms, but only during a specific process known as anaerobic respiration. Muscles usually receive energy through a process known as cellular respiration[15], but when there is a lack of oxygen in the organism, muscles go through anaerobic respiration.
