Explanation

• During the daytime, plants require Carbon Dioxide (CO2) for photosynthesis.
• Which is the process by which they produce glucose and oxygen.

Explanation

This is the photosynthesis reaction, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy.

Explanation

• Fungi are multicellular organisms, consisting of many cells that work together to form complex structures like mushrooms and molds.
• They have modified cell wall and nucleus.
• They have not chlorophyll.
• Animals, including humans, are multicellular organisms made up of many cells that work together to form tissues, organs, and systems.
• They have modified nucleus but don't have cell wall.
• They have not chlorophyll.
• Bacteria are unicellular organisms.
• They have cell wall but don't have proper nucleus.
• It doesn't contain chlorophyll.
• It is used to make medicines, yogurt and cheese.

Explanation

Signet ring cells are a hallmark of certain types of gastric cancer

Specifically signet ring cell carcinoma

Explanation

In the absence of sunlight, the entire food chain would become inactive and collapse because:

• Plants and algae, the primary producers, cannot undergo photosynthesis and produce energy.
• Herbivores cannot feed on plants, and carnivores cannot feed on herbivores.
• The energy flow from producers to consumers would be disrupted, leading to a collapse of the food chain.

Explanation

• Animals in grassland environments have broad feet or hooves that help them escape quickly from predators, such as lions, cheetahs, and hyenas.
• The broad feet provide stability and support for rapid movement, allowing them to run fast and efficiently.

Explanation

• Iron Rock is a non-living component, an abiotic factor.
• It is not included in the living components of the land environment.

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

• The skeleton provides support and protection for the human body and its internal organs. 
• It forms a framework that supports the body's muscles, organs, and tissues.
• It forms a framework that protects vital organs such as the brain, heart, and lungs.

Explanation

• The skeleton provides the structural framework that gives the body its shape and supports its various parts.
• It is made up of 206 bones that are connected by joints and held together by ligaments and tendons.
