Section -B Very Short answer type question (each has 2 marks).
16. Name at least four type of weather Hazards.

ANS. Cyclon, Heat Wave, Cold Wave, Hail Storm
17. Define Heredity?

ANS. Heredity is the biological process by which a parent passes genetic
characteristics or traits to their offspring through genes and DNA. This natural
transmission of traits from one generation to the next is often referred to as
inheritance
18. Define Enzymes.

Ans. Enzymes are biological catalysts, predominantly proteins, that speed up
biochemical reactions in living organisms without being consumed in the
process
19. Name atleast four livestock of india.

Ans. Cattle, Buffalow, horse, dog, cat.
20. Name at least two woolen animals.

Ans. Sheep, Merino, Angora Goat, Angora Rebbit.
OR
Define ruminant animal.

Ans. A ruminant is an herbivorous animal, such as a cow, sheep, or deer, that
has a specialized four-chambered stomach and the ability to regurgitate food
to chew it again in a process called rumination
21. Name atleast four fodder crops of haryana.

Ans. Sorghum, oat, barseem, maize
OR
What is Biofertilizer?

Ans. A biofertilizer is a substance, typically containing living microorganisms like
bacteria, fungi, or algae, that is applied to soil or seeds to promote plant growth by
increasing the supply and availability of essential plant nutrients, such as nitrogen
and phosphorus, ie BGA, Ozola, azatobector etc.

Section -C Short answer type question (each has 3 marks).
22. Write at least six blood group name.

Ans. A+, A-, B+, B-, O+, O-, AB+, and AB-

23. Describe self pollination and cross pollination.
Ans. Self-pollination is the transfer of pollen to the stigma of the same flower
or another flower on the same plant, which maintains genetic consistency but
can lead to weaker offspring, while cross-pollination is the transfer of pollen
between flowers of different plants, promoting genetic diversity, greater
adaptability, and healthier offspring but relying on external agents like wind or
insects
24. Wrirte short note on carbohydrates.

Ans. Carbohydrates are organic molecules made of carbon, hydrogen, and
oxygen that serve as the body's primary source of energy, breaking down into
glucose for immediate use or storage. They are categorized into simple carbs

(sugars like glucose and fructose found in fruits) and complex carbs (starches
and fibers found in grains, vegetables, and legumes)
25. What is difference between monosacchridees & disacchrides.

Ans. Monosaccharides are the simplest carbohydrates (simple sugars), like
glucose, fructose, and galactose, that cannot be broken down
further. Disaccharides are carbohydrates made of two monosaccharides
linked by a glycosidic bond. Common examples of disaccharides
are sucrose (glucose + fructose), lactose (glucose + galactose),
and maltose (glucose + glucose).
26. What is soil fertility? OR Describe role of nitrogen in plants.

Ans. Soil fertility is the capacity of soil to sustain healthy plant growth and
yield by providing essential nutrients, water, and air in adequate amounts and
proportions
OR
Role of nitrogen in plants: Nitrogen is absorbed by plant roots as nitrate or
ammonium ions, and deficiencies can lead to yellowing leaves and stunted
growth, while excess can cause weak, large leaves.
27. Write at least six organs of buffalo.

ANS. heart, liver, kidneys, lungs, stomach, and tongue.

OR
Write at least three indigenous breeds of cattle
Ans. 1. Gir · 2. Red Sindhi · 3. Sahiwal

Section -C Short answer type question (each has 3 marks).
28. Describe concepts and applications of of plant biotechnology.

Ans. Plant biotechnology is applied to improve crops for increased yield and
nutritional value, such as in pest-resistant and herbicide-tolerant crops and
bio-fortified varieties like Golden Rice. It also creates plants tolerant to
environmental stressors (drought, salt), produces plants that can synthesize
valuable chemicals or pharmaceuticals (including plantibodies), and facilitates
large-scale propagation and germplasm conservation of elite plant varieties
through tissue culture
OR
Difference between sexually propagated & asexually propagated crops.

Ans. Sexually propagated plants grow from seeds resulting from the fusion of
male and female gametes, creating genetically diverse offspring. In contrast,
asexually propagated plants grow from vegetative parts (like stems, leaves, or

roots) or specialized structures such as bulbs and tubers, yielding offspring
that are genetically identical clones of the parent plant.
29. Describe care and management of different livestock.

Housing and Environment

 Shelter:Provide clean, dry, and well-ventilated shelters that protect animals
from extreme weather conditions.
 Cleanliness:Regularly clean animal sheds and ensure proper drainage to
remove waste and prevent disease.
 Space:Offer adequate space for animals to move comfortably, and separate
sick animals for isolation.
Nutrition and Feeding

 Water:Ensure a constant supply of clean drinking water, as it is the most
crucial nutrient for livestock health.
 Balanced Diet:Provide appropriate and balanced nutrition to meet the
animals' growth and productivity needs.
 Feeders and Waterers:Use feeders and water troughs that minimize feed
loss and prevent contamination.
Health and Disease Management

 Veterinary Care:Monitor animals for signs of illness and consult a
veterinarian for timely treatment.
 Vaccination:Implement a vaccination program to prevent common diseases
that affect livestock.

30. Describe sign and symptoms of important disease of livestock and
poultry.

Ans. Important livestock diseases include Foot-and-Mouth Disease, Anthrax,
and Brucellosis, which are highly contagious and can cause significant
economic losses. Major poultry diseases are Newcastle
Disease and Infectious Bursal Disease, known for their high mortality rates
and the need for vaccination. Other critical diseases are Avian
Influenza, Marek's Disease, Fowl Cholera, and various bacterial and parasitic
infections in both livestock and poultry.
OR
What is the scope of poultry production in india?

The scope of India's poultry sector is vast and growing, driven by rising
domestic demand for protein-rich foods, increasing urbanization, and
favorable dietary shifts, leading to a projected significant market growth and
export potential. The sector is characterized by a fast-growing, largely
organized commercial segment contributing significantly to the economy and

employment, with opportunities for further development in processing, supply
chain optimization, and rural integration.
