• If a dividing tissue helps to increase the girth of the stem or root, then it's called Lateral meristem (cambium).
• If meristem is at the base of the leaves or internodes (on either side of the node) on twigs then it's called Intercalary meristem.

(4) Meristematic region of shoot 

Abscisic acid (ABA)

Most water used by agriculture stems from rainfall stored in the soil profile and only about 15 percent of water for crops is provided through irrigation. Irrigation therefore needs 900 km3 of water per year for food crops (to which some water must be added for non-food crops).

(a) Specific.

(b) Producers.

(c) Food Chain.

(d) Ecology.

(e) Non – biodegradable; Biodegradable.

• Chemicals like BHC and DDT induce carcinoma (muscle cancer) and growth of tumours.
• Handling of waste materials may cause skin, respiratory and intestinal infections.
• Non-biodegradable substances do not decompose easily so it produces land and water pollution.

Effluents and harmful gases are the main wastes, which are produced in a fertiliser factory. Suitable mechanism for waste management are:

• For control of gaseous pollutants combustion equipments are used which can be oxidised. The pollutants are exposed to a high temperature in the process. Air pollutants, such as certain gases and vapour and inflammable compounds are controlled through the use ’ of adsorption equipments. Adsorption is a surface phenomenon and it needs the presence of a large solid surface area. Toxic and odoriferous compounds are efficiently removed by this process.
•  Three options available for controlling the effluents are:
• Control can take place at the point of generation within the factory.
• Waste water can be pre-treated for discharge to municipal treatment systems.
•  Waste water can be treated completely at the factory and either reused or discharged directly for receiving water.

Hints— (a) Control air pollution
(b) The effluent should be treated before discharge into surrounding environment.

(i) Separation of biodegradable and non-biodegradable substances.
(ii) Gardening
(iii) Use of gunny bags/paper bags in place of polythene/plastic bags
(iv) Use of compost and vermicompost in place of fertilisers
(v) Harvesting rainwater

(a) Kitchen wastes
(b) Paper wastes like newspapers, bags, envelopes
(c) Plastic bags
(d) Vegetable/fruit peels/rind

Measures for disposal

(a) Segregation of biodegradable and non-biodegradable wastes.
(b) Safe disposal of plastic bags.
(c) Vegetable/fruit peels can be placed near trees/plants, which on decomposition will enrich the soil with nutrients.
(d) Give paper wastes for recycling.
(e) Prepare a compost pit for kitchen wastes.

Discarded unusable electronic gadgets such as computers, mobile phones, circuits, television sets, etc,, form electronic waste. These contain harmful toxic substances like heavy metals to which the unskilled manual workers are directly exposed.

a. Agricultural insect

1. False – Closed type 

2. True 

3. False – RBC is nucleated 

4. True

In cockroach the fertilized eggs are encased in capsule called Oothecae

If same quantity of electric current is passed through different electrolyte solutions, the amount of substances discharged are proportional to their equivalent masses.

The amount of substance discharged at any electrode during electrolysis is proportional to the quantity of electricity passed through the electrolyte.

Faraday's first law of electrolysis: The amount of chemical reaction which occus at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte (solution or melt).

b) Pharmaceutical waste

Expired, unused and contaminated drugs and vaccines are called Pharmaceutical waste.

(1) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Correct option is (1) (b)only

Correct option is (2) C₁₂H₂₂O₁₁

(2) (A) is correct but (R) is not correct

Correct option is (1) 5ml 

Preprocessor directives: These are the commands given to a program known as preprocessor that processes the source code before it passes through the compiler. Each of these preprocessor directives begins with a # symbol. These can be placed anywhere in the program but usually placed before main ( ) or at the beginning of the program. Before the source code passes through the compiler, it is examined by the preprocessor for any directives. If there are any, appropriate action is taken and the source program is handed over to compiler. These directives can be divided into following three categories:

1. Macro substitution directives

2. File inclusion directives.

3. Compiler control directives.

#include “filename”: The search for the file is made first in the current directory and then in the standard directories as mentioned in the include search path.

#include : This command would look for the file in the standard list of directories.

Both of these directives cause the entire contents of filename to be inserted into the source code at that point in the program. 

A C program to remove duplicates from an odered array:

#include<stdio.h>

#include<conio.h>

#include<string.h>

void main()

{

int i,j,k,l,flag=0;

char a[50];

clrscr();

printf("enter the characters in the array");

gets(a);

l=strlen(a);

for(i=0;i<l-1;i++)

 for(j=i+1;j<l;j++)

{

 if(a[i]==a[j])

 { l=l-1;

 for(k=j;k<l;k++)

 a[k]=a[k+1];

 flag=1;

 j=j-1;

 }

}

if(flag==0)

 printf("No duplicates found");

else

 for(i=0;i<l;i++)

printf("%c",a[i]);

getch();

}

Alwars were the famous Tamil Poet Saints of Tamil Nadu and also called as Azhwars. They praised the Hindu Supreme God Vishnu and his Avatar Krishna with their own composed songs. The Alwars had the belief that Vaishnavism and Lord Vishnu were the supreme beings and look after the devotees with compassion.

A C function to sort the characters of the string:

main()

{

char a[100],ch; int i,j;

printf ("\nEnter the string:-> ");

gets(a);

for (i=0;a[i]!='\0';i++)

{

for (j=i+1

a[j]!='\0';j++)

{

if (a[i]>a[j])

{

ch=a[i];

a[i]=a[j];

a[j]=ch;

}

}

}

printf ("\nString after sorting\n");

puts(a);

getch();

} 

a. Both assertion and reason are true, and reason is the correct explanation of assertion.
