E. coli is a prokaryotic organism, while the others are eukaryotic.

Euglena is classified under the kingdom Protista, which includes diverse unicellular organisms.

Starfish can regenerate lost arms, which is a form of asexual reproduction.

Hydra reproduces asexually by the process of budding, where a new individual develops from an outgrowth of the parent.

Budding is a form of asexual reproduction seen in organisms like Hydra, where a new individual develops from an outgrowth.

Starfish can reproduce by fragmentation, where a part of the organism can grow into a new individual.

Honeybees can reproduce by parthenogenesis, where an egg develops into an organism without fertilization.

Mammals reproduce sexually, while bacteria typically reproduce asexually, and fungi can reproduce both sexually and asexually.

Honeybees can reproduce through parthenogenesis, where unfertilized eggs develop into new individuals.

The UNHRC is responsible for promoting and protecting human rights around the world.

Al2O3 is an amphoteric oxide, reacting with both acids and bases.

Fluorine has the highest electronegativity among all elements.

Boron is a metalloid among the p-block elements.

Phosphorus is essential for life, particularly in DNA and ATP.

Boron is an essential micronutrient for plant growth.

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

Thallium is known for forming a stable +3 oxidation state.

Aluminum commonly forms stable +3 oxidation state compounds.

Neodymium (Nd) and Plutonium (Pu) are both f-block elements.

D-Glucose and L-Glucose are mirror images of each other, making them enantiomers.

Lanthanum (La) and Cerium (Ce) are both f-block elements, belonging to the lanthanide series.

1-pentanol and 2-pentanol differ in the position of the hydroxyl group, making them structural isomers.

Complementary angles are two angles whose sum is 90 degrees. All the given pairs meet this criterion.

Supplementary angles are two angles that add up to 180 degrees. An acute angle (less than 90 degrees) and an obtuse angle (more than 90 degrees) can add up to 180 degrees.

C and N will form a bond with the highest bond order of 3, as seen in the molecule CN.

C and N will form a stable diatomic molecule as they have suitable bond orders and electron configurations.

D-Glucose and L-Glucose are mirror images of each other, making them enantiomers.

C2H6 (ethane) and C2H5OH (ethanol) have different functional groups, making them functional isomers.

Cis-2-butene and trans-2-butene differ in the arrangement of groups around the double bond, making them geometric isomers.

Ethyl alcohol (ethanol) and dimethyl ether have the same molecular formula but different structures.
