Number 1

(1a)
(PICK ANY FOUR)
(i) Acting as antioxidants to protect cells from damage
(ii) Supporting immune function for overall health
(iii) Helping in the production of red blood cells
(iv) Aiding in the maintenance of healthy skin, hair, and nails
(v) Playing a role in energy production and metabolism
(vi) Supporting bone health and calcium absorption

(1b)
Fruit formation begins with the fertilization of the ovule in the flower, leading to the development of the seed within the ovary. The ovary then begins to grow and mature into a fruit, surrounding and protecting the developing seeds. As the fruit matures, it undergoes changes in size, color, texture, and taste to attract animals for seed dispersal. Once the fruit is fully mature, it is ready to be dispersed, allowing the seeds to be spread and germinate in new locations.

(1ci)
(PICK ANY FIVE)
(i) Singing or vocalizations
(ii) Displays of colorful plumage or markings
(iii) Ritualized movements or dances
(iv) Exchanging gifts or food offerings
(v) Pheromone releases or scents
(vi) Aggressive or territorial behaviors

(1cii)
(PICK ANY FOUR)
(i) Thin and moist to allow for efficient gas exchange
(ii) Large surface area to maximize the exchange of gases
(iii) Well-vascularized to facilitate the transport of gases
(iv) Protected from dehydration or damage
(v) Permeable to gases like oxygen and carbon dioxide
(vi) Adapted to the specific environment and respiratory needs of the organism

(1ciii)
(PICK ANY THREE)
(i) Stomata on the leaves
(ii) Lenticels on stems and bark
(iii) Root hairs
(iv) Hydathodes at leaf margins
(v) Air spaces within the plant tissues
(vi) Cuticles on the surface of leaves

NUMBER TWO

(2a)
(i) Muscle Contraction: When a person wants to bend their lower arm, the brain sends signals to the muscles in the arm to contract. This contraction shortens the muscle fibers, pulling on the tendons and causing movement at the elbow joint.
(ii) Joint Movement: The bending motion at the elbow joint is primarily due to the contraction of the biceps muscles. These muscles pull on the radius bone, causing it to move towards the humerus bone, resulting in the bending of the arm.
(iii) Antagonistic Muscles: To straighten the lower arm, the triceps muscles contract while the biceps muscles relax. This antagonistic muscle action allows for the extension of the arm at the elbow joint.
(iv) Nerve Signaling: Nerves play a crucial role in coordinating the muscle contractions needed for bending and straightening the arm. The brain sends signals through the nervous system to activate the appropriate muscles for the desired movement.
(v) Tendon Function: Tendons connect muscles to bones and transmit the force generated by muscle contractions to produce movement. In the lower arm, tendons play a vital role in transmitting the pulling force of muscles to bend and straighten the arm.
(vi) Joint Structure: The elbow joint’s anatomy, including the hinge joint formed by the humerus, radius, and ulna bones, enables the bending and straightening motion of the lower arm.

(2b)
Check the diagram below

(2ci)
(PICK ANY TWO)
(i) Parasites derive nutrients from living hosts While Saprophytes obtain nutrients from decaying organic matter.
(ii) Parasites harm their host while obtaining nutrients While Saprophytes decompose dead matter without harming living organisms.
(iii) Parasites rely on a living host for their nutritional needs While Saprophytes feed on dead and decaying organic material.
(iv) Parasites are dependent on their host for survival While Saprophytes can survive independently of other organisms.
(v) Parasites have special adaptations for attaching to hosts and obtaining nutrients While Saprophytes have enzymes for breaking down complex organic matter.
(vi) Parasites can weaken or harm their host, potentially leading to disease While Saprophytes help in the recycling of nutrients and enriching the soil.

(2cii)
(PICK ANY TWO)
(i) Dodder
(ii) Mistletoe
(iii) Rafflesia
(iv) Witchweed
(v) Broomrape
(vi) Indian Paintbrush

Number 4

(4ai)
A balanced diet is a diet that contains all the essential nutrients in the right proportions to maintain good health and proper functioning of the body.

(4aii)
[Draw the diagram]
Reticulate venation refers to a vein arrangement in which the veins form a complex network resembling a web or net. This type of venation is characteristic of dicotyledonous plants (dicots). A prominent midrib runs through the center of the leaf, from which lateral veins branch out. These lateral veins further divide into smaller veins called veinlets, creating the net-like pattern. Example of a plant with reticulate venation is the peepal tree (Ficus religiosa) or rose (Rosa indica).

(4bi)
(PICK ANY FIVE)
(i) Thick cuticle to reduce water loss.
(ii) Reduced leaf surface area to minimize water loss through transpiration.
(iii) Succulent stems or leaves to store water.
(iv) Deep and extensive root systems to absorb water efficiently.
(v) Hairy or waxy coatings to reflect sunlight and reduce water loss.
(vi) CAM (Crassulacean Acid Metabolism) photosynthesis to minimize water loss during the day.
(vii) Ability to go dormant during dry periods.
(viii) Spines or thorns to reduce water loss and protect against herbivores.

(4bii)
(PICK ANY THREE)
(i) Fixed joints
(ii) Freely movable joints
(iii) Slightly movable joints

(4ci)
(PICK ANY FOUR)
(i) Photosynthesis
(ii) Parasitic
(iii) Saprophytic
(iv) Holoparasitic
(v) Mixotrophic
(vi) Symbiotic

(4cii)
(PICK ANY TWO)
(i) Receptacle
(ii) Sepal
(iii) Petal
(iv) Stamen
(v) Pistil
(vi) Ovary

NUMBER FIVE

(5ai)
(i) Hypogeal germination
(ii) Epigeal germination

(5aii)
(PICK ANY FIVE)
(i) Auxins
(ii) Gibberellins
(iii) Cytokinins
(iv) Abscisic acid
(v) Ethylene
(vi) Brassinosteroids

(5b)
(i) Sweating: Sweat glands release sweat onto the skin. As the sweat evaporates, it absorbs heat from the body, cooling it down.
(ii) Vasodilation: Blood vessels near the skin surface widen, increasing blood flow to the skin. This allows more heat to escape through radiation, convection, and conduction.
(iii) Decreased Metabolic Rate: The body reduces its metabolic activity to limit internal heat production.
(iv) Behavioral Adjustments: Actions like seeking shade, reducing physical activity, or drinking water help cool the body.
(v) Panting or Heavy Breathing: Though less common in humans, rapid breathing increases heat loss through evaporation from the respiratory tract.

(5ci)
Draw the diagram below

(5cii)
(PICK ANY TWO)
(i) Lions
(ii) Tigers
(iii) Wolves
(iv) Cheetahs
(v) Eagles
(vi) Sharks
