Answer:
pH Scale:
The pH scale refers to the negative logarithm of molar concentration of hydrogen ions: pH = -log [H+].
Characteristics:
The pH scale ranges from 0 to 14. A solution of a compound of pH 7 or pOH 7 is a neutral solution. Solutions of pH less than 7 are acidic and more than 7 are basic.
Low pH of water is acidic in nature as it enters into the ground and collects in streams, it can have bad impacts on the ecosystem.
In biological taxonomy, the next smallest classification group after Order is Family. This is part of the classification system that ranges from broad categories to more specific ones, which include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
In the biological classification system, the next smallest group after Order is Family. This refers to the hierarchy of taxonomic ranks in biology, where organisms are classified from broad categories to more specific ones. The sequence of ranks from broad to specific is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each rank gets more specific as you go down the list. So, if you're looking at the rank just beneath Order, it would be Family. For instance, in the Order Carnivora (carnivores) one of the Families is Felidae (cats).

D. [Na] +3/[PO4) 3 -
The solubility product expression for Na3PO4(s) is [Na+]^3[PO4^3-], which denotes the ion concentration in the solution after the dissolution of sodium phosphate. therefore, option A is correct
The solubility product expression for Na3PO4(s) would be written as [Na+]^3[PO4^3-]. The solubility product, Ksp, is the equilibrium constant for the dissolution of a sparingly soluble substance. The solubility product expression depends on the stoichiometry of the dissolution reaction. Sodium phosphate, Na3PO4, dissociates in water into 3 sodium ions, Na+, and 1 phosphate ion, PO4^3-. Therefore, the solubility product expression is [Na+]^3[PO4^3-], where [Na+] and [PO4^3-] represent the molar concentration of these ions in the solution.

The solubility product expression of Na3PO4 is not among the given options because Na3PO4 is soluble in water and for soluble compounds, we don't write a solubility expression.
The solubility product expression is typically written for an ionic compound that is sparingly soluble in water. The solubility product expression of Na3PO4 is not among the options you've provided because every ionic compound has its own specific solubility product expression. Na3PO4 is soluble, so we don't write a solubility expression for it. In general, for a reaction where a solid dissolves in water such as A3B (s) ↔ 3A+ (aq) + B3- (aq), the solubility product expression would be [A+]^3 [B3-].

Answer: Anaerobic respiration
The available oxygen in the deer cell will be likely to deplete in running process. The anaerobic respiration will start immediately after the depletion of oxygen inside the muscle cells. The glucose breaks down in the absence of oxygen. The chemical reaction transfers the energy to the muscle cells to run.
Explanation:
These Rocks shown in photographs are made of different types of minerals which have properties as follows:
●The color of the rock is grey, brown and yellow after it is ground into a powder its color is streak.
● The lustre of the rock tells how shiny the rocks are.
● Other properties include hardness, texture, shape, and size.
