Diarrhoea is a condition where an individual experience a high frequency of loose and watery stools. The term is derived from the Greek words “Dia” and “rhein”, meaning “flowing through”. Usually, it is not a life-threatening disease and the duration of its symptoms usually vary as there are many causal factors.

Causes:

• Indigestion
• Infection
• Food poisoning

ORS stands for oral rehydration solution. It is given when body loses lot of wSter such as in diarrhoea.

Diarrhoea is a condition where an individual experience a high frequency of loose and watery stools. The term is derived from the Greek words “Dia” and “rhein”, meaning “flowing through”. Usually, it is not a life-threatening disease and the duration of its symptoms usually vary as there are many causal factors.
ORS: Oral rehydration solution is given to the person who faces dehydration usually when one has undergone diarrhea, vomiting, sweating, burns, and to travelers. Dehydration is a physical phenomenon where the body loses more amount of water. It is a mixture of sugar and electrolyte solutions used to treat dehydration. This solution is given to athletes, sportspersons after he finishes his match. During the sports activity one loses a large amount of water from the body due to sweat and gets feels tired. 

The food vacuole or digestive vacuole is a membrane-bound cell organelle (as in an amoeba) associated with a digestive function. They take up the food material by the process of phagocytosis and the ingested food is digested by food vacuole.

• The food gets trapped inside food vacuole, into which digestive juices are secreted and convert them into simpler substances.
• The digested food is then absorbed which is required for growth, maintenance and multiplication.
• The undigested food is expelled out by vacuole.

Both Amoeba and humans require energy for the growth and maintenance of their bodies. This energy is derived from the food they eat. The food is in a complex form and is therefore broken down into simple forms by the process of digestion. Both these organisms are heterotrophs as they derive their food from other plants or animals. Difference between nutrition in Amoeba and human beings is gives below:  

- 4(2 + x) = 8

- 4(2) -4 (x) = 8

- 8 - 4x = 8

-4x = 8 + 8

-4x = 16

x = 16/-4

x = -4

- 4(2 + x) = 8

- 4(2) -4 (x) = 8

- 8 - 4x = 8

-4x = 8 + 8

-4x = 16

x = 16/-4

x = -4

To construct: A pair of parallel lines intersecting other part of parallel lines.

Steps of construction:

(a) Draw a line l and take a point P outside of l .

(b) Take point Q on line l and join PQ.

(c) Make equal angle at point P such that ∠ Q = ∠ P.

(d) Extend line at P to get line m.

(e) Similarly, take a point R online m, at point R, draw angles such that ∠ P = ∠ R.

(f) Extended line at R which intersects at S online l. Draw line RS.

Thus, we get parallelogram PQRS.

Insectivorous means insect-eating, these plants derive most of their nutrition from the insects, that they trap and consume. These plants grow in humid areas, where plenty of sunlight and moisture is found. They are found in the nitrogen deficient soil. That is why they trap and digest insects to absorb nutrients. Venus flytrap, pitcher plant and cobra lily are some of the insectivorous plants’ names. They are often called Carnivorous plants.

Rainfall can be defined as the precipitation in the liquid form. 
Rainfall has been classified into three main types based on the origin –

• Convectional rainfall
• Orographic or relief rainfall
• Cyclonic or frontal rainfall

Write equations for the following statements:

Q : If you take away 6 from 6 times y, you get 60.

A n s w e r :
6 (y-1) = 60

6y - 6 = 60

6y = 66

y =11

Mode of nutrition in Pitcher plant: Plants which grow in nitrogen deficient soil derive their nitrogen from insects, e.g., pitcher plant etc.

Pitcher Plants : Leaf blade or lamina is modified into sac like structure known as pitcher. Leaf apex forms the lid of the pitcher which is lined by nectar secreting glands. Internal lining of the pitcher has digestive glands which secrete proteolytic enzymes to digest proteins of the trapped insects. To trap the insect pitcher has following modifications: 

(i) Insects are attracted by coloured lid and nectar.

(ii) Neck of the pitcher bears bristles pointing inward and downward which pierces the body of the escaping insects and kills them.

(iii) Inner portion of pitcher is slippery and contain acidic fluid by which insects slips down and gets drowned in the fluid. 

(iv) Once the insect is trapped and killed, it is digested and end products of digestion mainly amino acids are absorbed by the pitcher walls.

A Cyclone is a large scale air mass that rotates around strong centers of low pressure.

• Water vapors are formed when water is heated.
• This heat is released to atmosphere when water vapors convert to water during rains.
• The heat released, warms the air around and makes it to move up. This also results in decreased air pressure.
• Hence, cooler air from surrounding rushes to take the warm air’s place.
• This repeats till a low pressure system with surrounding high speed winds is created. This is called a Cyclone.
• Cyclone depends on wind speed, direction, temperature and humidity.

Cyclones are also called Hurricane in USA and Typhoon in Japan and Philippines

The two ways in which Article 15 addresses inequality are: (i) The State shall not discriminate against any citizen on grounds only of religion, race, caste, ***, place of birth or any of them. (ii) No citizen shall, on grounds only of religion/ race, caste, ***, place of birth or any of them, be subject to any disability, liability, restriction or condition with regard to : (a) access to shops, public restaurants, hotels, and places of public entertainment; (b) the use of wells, tanks, bathing ghats, roads, and places of public resort maintained by the funds of State or meant for public use.  

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

The most basic and common algebraic equations in math consist of one or more variables.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. 

34(-49)

= -  1666

 (-25)+60+(-95)+(-385)

= - (25 + 95 + 385) + 60

= - 505 + 60
= - 445
