Tropical rainforests are known for their high biodiversity due to favorable climatic conditions.

Tropical rainforests are known for having the highest biodiversity among ecosystems.

Lead does not form a stable +4 oxidation state; it is more stable in the +2 state.

Lead does not form a stable oxide in the same way as the other elements listed.

The electron configuration [Ne]3s²3p⁵ corresponds to Chlorine, which has 17 electrons.

Lithium (Li) has the highest ionization energy among the alkali metals due to its smaller atomic size.

Lithium (Li) has the highest melting point among the alkali metals due to its smaller size and stronger metallic bonding.

Sodium (Na) is an alkali metal, while Magnesium (Mg), Calcium (Ca), and Barium (Ba) are alkaline earth metals.

Calcium is a member of the alkaline earth metals, which are found in Group 2 of the periodic table.

Iron is classified as a micronutrient, required in smaller amounts compared to macronutrients.

Calcium is classified as a secondary macronutrient, important for cell wall structure and stability.

Aluminium commonly forms a stable +3 oxidation state in its compounds.

Tin (Sn) is known for forming a stable +4 oxidation state.

Copper (Cu) is known for its ability to form complex ions due to its d-orbitals.

Aluminum (Al) is not an alkaline earth metal; it is a post-transition metal.

Both amylase and trypsin are enzymes secreted by the pancreas to aid in digestion.

Neodymium is used in making strong permanent magnets, known as neodymium magnets.

The shape of the objects does not affect the gravitational force; only mass and distance do.

The color of the objects does not affect the gravitational force between them.

Soil type does not directly affect the rate of transpiration; however, it can influence water availability.

The length of the specimen does not affect tensile strength; it is an intrinsic property of the material.

Abiotic factors are non-living chemical and physical components of the environment, such as sunlight, temperature, and water.

Alcohols contain the hydroxyl functional group (-OH).

Helium behaves most like an ideal gas due to its low intermolecular forces and small size, making it closer to the ideal gas behavior.

At the same temperature, lighter gases have higher average speeds. Hydrogen (H2) has the lowest molar mass and thus the highest average speed.

The kingdom Animalia includes only multicellular organisms.

Eukarya is characterized by the presence of a true nucleus in its cells.

Bacteria are known for being prokaryotic organisms.

Birds are the only group of animals that possess feathers, which are essential for flight and insulation.

Birds are the only group of animals characterized by the presence of feathers.
