Explanation

Both senses detect chemicals—smell through the nose and taste through the tongue.

They work together to enhance flavor perception.

Explanation

Ribosomes are tiny organelles found in both prokaryotic and eukaryotic cells.

They are responsible for synthesizing proteins by linking amino acids according to genetic instructions.

Explanation

Rock candy is made by crystallizing sugar from a supersaturated solution using a seed crystal.

This process is known as the seedling technique, where crystals slowly grow over time.

Explanation

A species is defined as a group of organisms that can mate and produce fertile offspring.

Organisms in different genera generally cannot produce fertile offspring.

Explanation

Steam causes more severe burns than boiling water because it carries latent heat of vaporization.

It releases extra energy when it condenses on the skin.

Explanation

Meiosis is a type of cell division that reduces the chromosome number by half and is essential for the formation of germ cells (sperm and egg).

It ensures genetic diversity.

It is fundamental to sexual reproduction.

Explanation

Friendly bacteria in our large intestine produce Vitamin K, which helps in blood clotting.

These bacteria mainly synthesize Vitamin K2, important for bone and heart health.

Explanation

Metals are opaque, meaning they do not allow light to pass through.

They are malleable (can be hammered into thin sheets) and lustrous (shiny in appearance).

Explanation

Valency is the number of electrons an atom can gain, lose, or share to achieve a stable configuration.

Carbon (C) has an atomic number of 6, with an electron configuration of 2,4.

It needs 4 more electrons to complete its outer shell (octet rule), so its valency is 4.

Explanation

Echinoderms (such as starfish, sea urchins, and sea cucumbers) are invertebrates because they lack a backbone.

They have a unique water vascular system and radial symmetry.
