Hearing is considered _____________, because the ear receives mechanical vibrations and translates them into nerve impulses.
andriy [413]

Answer:

Mechanoreception

Explanation:

Mechanoreception is usually defined as the ability of an organism, such as humans and animals, to perceive and react to certain types of stimuli. This may include a sensation like sound, touch, that are produced in an environment.

This involves the conversion of sound waves (which are mechanical vibrations) into nerve impulses which are in the form of electrical signals. Initially, this process starts with the vibration of the eardrum and immediately transmits these vibrations towards the three small bones that are located in the middle portion of the ear. These are then carried by the auditory nerve into the brain. The brain finally converts this information into electrical signals. This entire process eventually leads to the creation of sound within the temporal lobe inside the brain.

Live cultures of bacillus thuringiensis (dipel) and
sammy [17]

These bacillus thuringensis species of bacteria secrete protein crystals that are toxic to most insects hence used in agriculture to kill pests that attack the crops. This is also the reason the genes responsible for this protein crystal is incorporated in crops (transgenic crops) to make them resistant to pests.

B. subtilis is important in the nutrient cycle and availing nutrient to plants hence promote plant growth

Both species are able to survive harsh conditions and remain dormant for long periods of time as spores hence their suitability in application in agriculture

bagirrra123 [75]

The correct answer is filtration.

The small molecules can cross in and out of the capillaries through facilitated or simple diffusion. However, the majority of the flow of capillary and tissue fluid takes place through the process of filtration and reabsorption. Filtration refers to the movement of the fluid out of the capillaries and is mediated by the capillary hydrostatic pressure.
