Explanation

Vertebrates are animals that have a backbone or spinal column. This group includes:

• Fish
• Amphibians
• Reptiles
• Birds
• Mammals (including humans)

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

• Plants are multicellular, composed of many cells that work together to form roots, stems, leaves, and other structures.
• They have modified cell wall and nucleus.
• They have chlorophyll.
• Algae are unicellular with proper cell wall and nucleus.
• It contain chlorophyll.
• It causes diseases: Cutleria, Ulva and Volvox.

Explanation

• The orbit of the Earth around the Sun is an ellipse, meaning that it is an elongated circle, with the Sun located at one of the two foci (plural of focus) of the ellipse.
• This means that the distance between the Earth and the Sun varies throughout the year.
• With the closest point (perihelion) occurring around early January.
• With the farthest point (aphelion) occurring around early July.
  

Explanation

• Wood is an insulator and cannot conduct electricity.
• So it cannot be used to complete a circuit.

Explanation

• A closed circuit provides a complete path for the current to flow through.
• It allowing electricity to flow from the power source, through the wire, and back to the power source.

Explanation

• A close circuit, also known as a closed circuit.
• It is an electrical circuit that is complete and allows electricity to flow from the power source, through the wire, and to the bulb, causing it to light up.

Explanation

• A thermal conductor is a material that allows heat energy to flow through it easily.
• Such as metals like copper, aluminum, and iron.
