They are carbohydrates.

Answer 1

Answer-1: NUTRIENTS ( it is a substance required for an organism to survive and grow)

Answer-2: THORACIC IS VENTRAL TO SPINAL CAVITY ( as thoracic is present at the anterior or ventral part and spinal cavity is at the posterior or dorsal part)

Answer-3: ABDOMINOPELVIC CAVITY (divided into 2 divisions- abdominal cavity, comprises of stomach, spleen,intestines, liver and the pelvic cavity comprising of bladder, rectum, other reproductive organs, etc.)

Answer-4: TRANSVERSE (axial plane)

Answer-5: DISTAL AND PROXIMAL (distal is away from the point of attachment and proximal is close to point of attachment to the body)

Answer-6: PASS THROUGH BOTH EARS ( as coronal section divides the body into ventral and dorsal sections )

Answer-7: CARBON, OXYGEN, HYDROGEN, NITROGEN (most abundant elements in living beings)

Answer-8: NON POLAR COVALENT BONDS ( atoms of same elements attract electrons equally and thus equal sharing of electrons occurs )

Answer-9: Protons are positively charged, electrons are negatively charged, and neutrons are neutral

Answer-10: CARBOHYDRATES ( especially polysaccharides)

Answer-11: Enzymes—proteins (almost all enzymes are protein in nature)

Answer-12: They are biological catalysts (they enhance the rate of reactions in our body by lowering the activation energy).
