• Such as plants, animals, water, air, soil, and sunlight.

Explanation

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

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

• Frog eggs are known as Spawn.
• This term refers to the cluster of eggs laid by a female frog in water.

Explanation

• The larval stage of a frog is known as Tadpoles.
• This stage is characterized by a aquatic, fish-like body, with gills for breathing and a tail for swimming.

Explanation

• Frogspawn (Eggs): Laid by the female frog in water.
• Tadpoles (Larvae): Hatch from eggs, aquatic, and feed on algae.
• Froglet (Young Frog): Undergo metamorphosis, develop limbs, and lose tail.
• Frog (Adult): Fully developed, breathing air, and reproducing.

Explanation

• It including embryonic development, childhood, adolescence, and adulthood.

Explanation

• A species is a group of living organisms that share common characteristics, can interbreed, and produce fertile offspring.
• A particular group of animals or plants that belong together and have some similar quality.

Explanation

 Ecology is the scientific study that is related to the environment which includes both living and non-living factors. Histology is the scientific and clinical study of cells, organs and tissues based on the observation under the surface of microscope.

Explanation

Both plant and animal cells are eukaryotic.

Animal cells have centrosomes , whereas Plant cells have a cell wall.
