Tasting and smelling both involve the ability to sense chemicals. true or false
lara31 [8.8K]
TRUE.
Taste and smell senses are separate senses with their own receptor organs yet they are intimately entwined. Tastants, chemicals in foods are detected by taste buds which consist of special sensory cells.. When stimulated, these cells send signals to specific areas of the brain which then makes us conscious of the perception of taste. Also specialized cells in the nose pick up odorants, airborne odor molecules. Odorants stimulate receptor proteins found on hairlike cilia at the tips of the sensory cells, a process that initiates a neural response.

Which two options are forms of kinetic energy?
juin [17]

Answer:

B. Thermal energy

E. Sound energy

Explanation:

Thermal and sound energy is kinetic energy.

Kinetic energy is the energy that results as a function of the motion of a body or the particles of the medium.

Sound energy is transmitted by the vibration of the particles in the air. The vibration leads to movement of the particles and hence, kinetic energy is produced.

Thermal energy originates as a result of the temperature differences in a body. This temperature difference leads to the increase in the kinetic energy of some particles which also causes vibration and motion of the particles.
