Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores. A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.

In conversion of mixed fractions into improper fractions, we may follow the following steps:
Step I: Obtain the mixed fraction. Let the mixed fraction be 22/5
Step II: Identify the whole number and the numerator (top) and denominator (bottom) of the proper fraction.
Step III: Multiply the whole number by the denominator of the proper fraction and add the result to the numerator of the proper fraction.
Step IV: Write the fraction having numerator equal to the number obtained in step III and denominator same as the denominator of the fraction in step II. Thus,

A cylinder can be seen as a collection of multiple congruent disks, stacked one above the other. In order to calculate the space occupied by a cylinder, we calculate the space occupied by each disk and then add them up. Thus, the volume of the cylinder can be given by the product of the area of base and height.
For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base times the height.
Therefore, the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder
Since the base is the circle, it can be written as
Volume = πr2 × h
Therefore, the volume of a cylinder = πr2h cubic units.

An oxidation number can be assigned to a given element or compound by following the following rules.
- Any free element has an oxidation number equal to zero.
- For monoatomic ions, the oxidation number always has the same value as the net charge corresponding to the ion.
- The hydrogen atom (H) exhibits an oxidation state of +1. However, when bonded with an element with less electronegativity than it, it exhibits an oxidation number of -1.
- Oxygen has an oxidation of -2 in most of its compounds. However, in the case of peroxides, the oxidation number corresponding to oxygen is -1.
- All alkali metals (group 1 elements) have an oxidation state of +1 in their compounds.
- All alkaline earth metals (group 2 elements) exhibit an oxidation state of +2 in their compounds.
- In the compounds made up of two elements, a halogen (group 17 elements) have an oxidation number of -1 assigned to them.
- In the case of neutral compounds, the sum of all the oxidation numbers of the constituent atoms totals to zero.
- When polyatomic ions are considered, the sum of all the oxidation numbers of the atoms that constitute them equals the net charge of the polyatomic ion.
Thus, the oxidation number of an atom in a given compound can be calculated with the steps mentioned above.

Autonomic nervous system is a part of peripheral nervous system which is responsible for involuntary actions i.e. it regulates all those actions or responses of our body that are not according to our will. Example - beating of heart.
It has two parts:
i. Sympathetic nervous system
ii. Parasympathetic nervous system
The nerve fibres of both these parts have opposing effects i.e. if one stimulates a particular response, the muscles of other system inhibits that response.

Mahmud of Ghazni was the first independent ruler of the Turkic dynasty of Ghaznavids, ruling from 999 to 1030. At the time of his death, his kingdom had been transformed into an extensive military empire, which extended from northwestern Iran proper to the Punjab in the Indian subcontinent, Khwarazm in Transoxiana, and Makran.
Highly Persianized, Sultan Mahmud continued the bureaucratic, political, and cultural customs of his predecessors, the Samanids, which established the ground for a Persianate state in northwestern India. His capital of Ghazni evolved into a significant cultural, commercial, and intellectual centre in the Islamic world, almost rivalling the important city of Baghdad. The capital appealed to many prominent figures, such as al-Biruni and Ferdowsi.
Mahmud ascended the throne at the age of 27 upon his father's death, albeit after a brief war of succession with his brother Ismail. He was the first ruler to hold the title Sultan ("authority"), signifying the extent of his power while at the same time preserving an ideological link to the suzerainty of the Abbasid Caliphate. During his rule, he invaded and plundered the richest cities and temple towns in medieval India seventeen times, and used the booty to build his capital in Ghazni.

Answer:
there are two methods to solve the problem which are discussed below.
Method 1:
Let us consider
a = n3 – n
a = n (n2 – 1)
a = n (n + 1)(n – 1)
Assumtions:
1. Out of three (n – 1), n, (n + 1) one must be even, so a is divisible by 2.
2. (n – 1) , n, (n + 1) are consecutive integers thus as proved a must be divisible by 3.
From (1) and (2) a must be divisible by 2 × 3 = 6
Thus, n³ – n is divisible by 6 for any positive integer n.
Method 2:
When a number is divided by 3, the possible remainders are 0 or 1 or 2.
∴ n = 3p or 3p + 1 or 3p + 2, where r is some integer.
Case 1: Consider n = 3p
Then n is divisible by 3.
Case 2: Consider n = 3p + 1
Then n – 1 = 3p + 1 –1
⇒ n -1 = 3p is divisible by 3.
Case 3: Consider n = 3p + 2
Then n + 1 = 3p + 2 + 1
⇒ n+1 = 3p + 3
⇒ n+1 = 3(p + 1) is divisible by 3.
So, we can say that one of the numbers among n, n – 1 and n + 1 is always divisible by 3.
⇒ n (n – 1) (n + 1) is divisible by 3.
Similarly, when a number is divided by 2, the possible remainders are 0 or 1.
∴ n = 2q or 2q + 1, where q is some integer.
Case 1: Consider n = 2q
Then n is divisible by 2.
Case 2: Consider n = 2q + 1
Then n–1 = 2q + 1 – 1
n – 1 = 2q is divisible by 2 and
n + 1 = 2q + 1 + 1
n +1 = 2q + 2
n+1= 2 (q + 1) is divisible by 2.
So, we can say that one of the numbers among n, n – 1 and n + 1 is always divisible by 2.
∴ n (n – 1) (n + 1) is divisible by 2.
Since, n (n – 1) (n + 1) is divisible by 2 and 3.
Therefore, as per the divisibility rule of 6, the given number is divisible by six.
n3 – n = n (n – 1) (n + 1) is divisible by 6.

As the electorate expanded, the political parties evolved to mobilize the growing mass of voters as the means of political control. ... In recent decades, increasing numbers of individual voters classify themselves as “independent,” and they are permitted to register to vote as such in many states. Representatives are chosen by citizens to serve in legislative bodies and to voice their concerns to the government. The legislature of the United States government is referred to as Congress. The job of Congress is to make the laws and policies of the United States.
