Microorganisms like bacteria are single cellular whereas some algae and fungi are multicellular. They are found in all types of habitats. They can live and survive in almost all kinds of environment like hot springs, ice-cold waters, saline water, desert soil or marshy land. Microorganisms can be present inside the human body or that of animals as parasites.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8.

Let the units digit of the two-digit number be x.
Then, the tens digit of the two-digit number = 9 – x
[{tex}\because {/tex} Sum of the digits of the two-digit number 9]
∴ Original number = 10(9 – x) + x
= 90 – 10x + x
= 90 – 9x
When we interchange the digits, then
Units digit = 9 – x
and, tens digit
∴ Resulting number = 10x + (9 – x)
= 9x + 9
According to the question,
(9x + 9) = (90 – 9x) + 27
∴ 9x + 9x = 90 + 27 – 9. . . . [Transposing – 9x to L.H.S. and 9 to R.H.S.]
∴ 18x = 108
{tex}x = \frac{{108}}{{18}}{/tex} . . . . [Dividing both sides by 18]
∴ x = 6
∴ 9 – x = 9 – 6 = 3  hence, the required two–digit number is 36.
Verification
3 + 6 = 9
63 = 36 + 27 hence, result verified.

According to the question, {tex}f ( x ) = 1 - | x + 2 |{/tex}
We can see that {tex}f(x){/tex}( x ) is defined for all x {tex}\in{/tex} R.
{tex}\therefore{/tex} Domain of f = R

As we know, {tex}0 \leq | x + 2 | < \infty{/tex}for all {tex}x \in R{/tex}
{tex}\Rightarrow - \infty < - | x + 2 | \leq 0{/tex} for all {tex}x \in R{/tex}
{tex}\Rightarrow - \infty < 1 - | x + 2 | \leq 1{/tex} for all {tex}x \in R.{/tex}
{tex}\Rightarrow - \infty < f ( x ) \leq 1{/tex} for all {tex}x \in R \Rightarrow f ( x ) \in ( - \infty , 1 ]{/tex}
{tex}\therefore{/tex} Range of {tex}f = ( - \infty , 1 ]{/tex}

Ear barotrauma is caused by air pressure changes at higher elevations and results in discomfort and pain in the ear(s). When barotrauma causes vertigo, this can indicate damage to the inner ear and may be associated with hearing loss. In addition to your ears, high altitude can affect your overall health. Our ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your ear drum.

An electrolyte is a substance that dissociates into ions in solution acquires the capacity to conduct electricity. Thus, electrolytic solutions contain only ions. So the charge carrier will be ion. An electrolyte solution is a solution that generally contains ions, atoms or molecules that have lost or gained electrons, and is electrically conductive. For this reason they are often called ionic solutions, however there are some cases where the electrolytes are not ions.

Deepshikha Kumari 6 years, 2 months ago

1. Peat 2. Lignite 3. Bituminous 4. Anthracite

Deepshikha Kumari 6 years, 2 months ago

1. Peat - It is the first stage in the formation of coal and therefore it is light and brown in colour. It contains 50 to 60%of carbon 2 . lignite - It is the second stage in the formation of coal. It is also brown in colour and it contain more than 60% of carbon but it is harder than Peat. Bituminous - It is the third stage in the formation of coal. It contain approx 70 to 75%carbon. 3. Anthracite - It is the purest variety of coal. It is hard, dense, and black. It is difficult to ignite but once ignited it burns a lot of heat and for a very long time.
