Explanation
Vitamins play a crucial role in protecting us from many diseases , such as: Vitamin C : boosts immune system, fights off infections Vitamin D : essential for bone health, prevents rickets and osteomalacia Vitamin E : acts as an antioxidant, protects cells from damage Vitamin K : necessary for blood clotting, prevents bleeding disorders

Explanation
Fruits and vegetables are rich in various vitamins, such as: Vitamin C ( citrus fruits , strawberries, bell peppers ) Vitamin A (sweet potatoes, carrots, dark leafy greens) Vitamin K (leafy greens, broccoli , cauliflower) Folate (dark leafy greens, citrus fruits, legumes )

Explanation
Minerals are essential nutrients that play a crucial role in many bodily functions, including: Building strong bones and teeth Regulating body functions Maintaining healthy immune systems Supporting nerve and muscle function

Explanation
Minerals such as Potassium, Fiber, Iron, and Selenium are found in fruits, vegetables, grains, and seafood.

Explanation
Carbohydrates are the body's primary source of instant energy. They are broken down into glucose . Which is absorbed into the bloodstream and transported to cells throughout the body. Where it is converted into energy.

Explanation
Peanuts are a legume and a good source of protein, containing about 20.5 grams of protein per 100 grams. Apples : 0.3 grams of protein per medium-sized fruit Watermelon : 0.6 grams of protein per cup Mango : 1.4 grams of protein per cup

Explanation
Apples contain about 0.3 grams of protein  medium-sized fruit. Watermelon : 0.6 grams of protein per cup. Mango : 1.4 grams of protein per cup. Peanuts : 20.5 grams of protein per 100 grams.

Explanation
Proteins are an essential nutrient that helps our body grow and repair tissues and muscles. They are made up of amino acids, which are the building blocks of protein. Proteins are necessary for: Building and repairing muscle tissue Supporting growth and development Maintaining healthy skin, hair, and nails Producing enzymes and hormones

Explanation
Protein is referred to as "body building" food. Because it provides the necessary building blocks for growth, maintenance, and repair of tissues in the body. It is essential for building and repairing muscles , bones, skin, hair, and nails, as well as producing enzymes and hormones.

Explanation
Milk, meat, eggs, and pulses are all rich sources of Protein, which is essential for: Building and repairing tissues Producing enzymes and hormones Maintaining healthy muscles, bones, and organs

Explanation
The larval stage of a bee is known as a Grub . This stage is characterized by a legless , worm-like body, fed royal jelly and pollen by worker bees.

Explanation
The life cycle of a bee : Egg : Laid by the queen bee in the honeycomb cell. Larva (Grub) : Hatches from the egg, fed royal jelly and pollen. Pupa (Cocoon) : Transforms into a pupa, undergoing metamorphosis. Bee (Adult) : Emerges from the pupa, ready to fly and perform colony tasks.

Explanation
Potato, wheat, rice, corn , and sweet fruits are all rich in carbohydrates . Carbohydrates are an important source of energy for the body.

Explanation
Heredity is the property that passes similar characteristics from parents to their offspring , making a human baby similar to human beings.

Explanation
In mammals, approximately 70% of their body weight is made up of water. This water is distributed throughout the body and is found in various tissues and organs, including: Blood (83% water) Muscles (75% water) Brain (75% water) Bones (25% water) Skin (60% water)

Explanation
Both animal and plant bodies contain a significant percentage of water. 70% is a commonly cited estimate for many living organisms.

Explanation
Plants prepare their food (glucose) through photosynthesis. Which requires sunlight , water , carbon dioxide, and chlorophyll. Sunlight provides the energy needed to power the photosynthetic process.

Explanation
Plants absorb Carbon Dioxide (CO2) during the daytime through tiny openings on their leaves called stomata. They use this carbon dioxide, along with water (H2O) and light energy from the sun , to produce glucose (C6H12O6) and oxygen (O2) through the process of photosynthesis.

Explanation
The life cycle of a bean plant : Seed : The plant begins as a seed, containing the embryo and stored food. Germination : The seed absorbs water, sprouts, and grows its first roots and leaves. Leaf growth : The plant develops its leaves, stems, and roots, and begins to photosynthesize. Flowering : The plant produces flowers, which contain the reproductive organs and allow for pollination.

Explanation
The pupal stage of a bee is known as a Cocoon . This stage is characterized by a resting, non-feeding state , where the larva transforms into an adult bee.

Explanation
The larval stage of a bee is known as a Grub . This stage is characterized by a legless , worm-like body, fed royal jelly and pollen by worker bees.
