Nephrons are the microscopic structural and functional unit of the kidney. Nephrons are composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman’s capsule.
Structure of a Nephrons:
- Nephrons are the basic filtering units of kidneys.
- Each kidney possesses large number of nephrons, approximately 1-1.5 million.
- The main components of the nephron are glomerulus, Bowman’s capsule, and a long renal tubule.

We know that,
an=a+(n-1)d
So,a20=a+(20-1)(3)
a20=a+19(3)
a20=a+57
Similarly, a15=a+14d
a15=a+14(3)
a15=a+42
Now,a20-a15=(a+57)-(a+42)
=a+57-a-42
=57-42
=15

History:
The number system is a mathematical notation which is used to represent numbers of a given set. The number system with which we are most familiar is the decimal (base-10) system. It is also known as system of numeration or numeral systems which helps us to express numbers using digits or other symbols.
Basically, the number system represents a meaningful set of numbers including integers , rational numbers. Each and every no. shows the algebraic and arithmetic numbers.
In ancient times, various systems for number system were used such as the ancient Egyptians, the ancient Babylonians.
But , now - a -days, the Decimal Number System is used.
For example: 123.
This shows three numerals : 1,2,3. Because we use a place value system, which shows , 1 is 100, 2 is 20 and 3 is 3 as it stands in the ones place.
So, instead of writing 100+20+3, we write 123
Types of Number System:
a) Natural Numbers: Natural numbers are the numbers 1, 2, 3, ...
b) Integers: All natural numbers are integers including 0, -1, -2, ...
c) Rational numbers: These are fractions p/q where q is non-zero and p and q are both integer.
For example, all integers are rational (pick q =1).
Other examples of rational numbers are 3/2, -5/7, -1232321/74567467.
d) Real numbers: Real numbers are all numbers that can be written as a possibly never repeating decimal fraction.
e) Complex numbers: These are numbers in form of
z = a+ bi, where a and b are real numbers and i (called the imaginary unit)is the square root of negative 1, i.e.,
.
f) Algebraic numbers:These are complex numbers that can be obtained as the root of a polynomial with integer
coefficients. For example, rational numbers are algebraic, and so are roots of integers.
g) Transcendental numbers: These numbers are real numbers. For example e and π are transcendental (and real).
Properties of Numbers:
1) Associative Property:
In case of addition : a+(b+c)=(a+b)+c
In case of multiplication: a.(b.c)=(a.b).c
2) Commutative Property:
In case of addition : a+b=b+a
In case of multiplication: a.b=b.a
3) Inverse Property:
In case of addition : a+(-a)=0
In case of multiplication: a.(1/a)=1
4) Distributive Property:
a.(b+c)=a.b+a.c

x2 + bx +12=0.
2 is a root of the equation.
Then, 4+2b+12=0.
Then, 2b+16=0.
So, 2b= -16.
Therefore, b= -8.
x2+bx+q=0.
x2-8k+q=0.
Equal roots, so b2 =4ac.
64=4 × 1×q
q=16.

Let given quadratic polynomial be p(x) =x2 + 99x + 127.
On comparing p(x) with ax2 + bx + c, we get
a = 1, b = 99 and c = 127
Hence, both zeroes of the given quadratic polynomial p(x) are negative.

Sequences: A finite sequence is a sequence that contains the last term such as a1, a2, a3, a4, a5, a6……an. On the other hand, an infinite sequence is never-ending i.e. a1, a2, a3, a4, a5, a6……an…..
Series: In a finite series, a finite number of terms are written like a1 + a2 + a3 + a4 + a5 + a6 + ……an. In case of an infinite series, the number of elements are not finite i.e. a1 + a2 + a3 + a4 + a5 + a6 + ……an +…..

Prime number : A number is called a prime number, if it has no factor other than one and the number itself.
LCM : LCM of two or more numbers = product of the greatest power of each common prime factor involved in the numbers, with highest power.
SOLUTION :
Given : p & q are two Prime numbers.
We know that , prime numbers have only two factors 1 and the number itself.
Let p = 3 and q = 5
The factors of p and q are as follows :
p = 3 × 1
q = 5 × 1
LCM (3,5) = 3 × 5 = 15
Hence, LCM(p,q) is pq

A n s w e r is as follows :
36 = 2 x 2 x 3 x 3
198 = 2 x 3 x 6 x 18 x 11
LCM ( 36,198 ) = 2 x 2 x 3 x 3 x 6 x 18 x 11
= 396
the value of d = 396

Euclid damma division theorem
a=2q,2q+1, where 2 is a whole number.
a2=(2q)2=4q2=4m , where q is a whole number.
a2=(2q+1)2=4q2+4q+1 = 4m+1 where m=(q2+q)
