The correct answer is frequency.

The pitch can be defined as the quality of sound produced by the rate of vibration producing it.

It is directly related to the the frequency of the sound wave. If the frequency is increased then its pitch will also increase and vice versa.

As for normal people it is a bit difficult to differentiate between the two but the musician are trained so they can differentiate the difference between the two even if the difference is 2 Hz

Answer:

Communicate with one another by means of solvent variables.  

Explanation:

Numerous microbes are known to coordinate their pleasant activities and physiological techniques through a framework called majority detecting in which bacterial cells talk with each other by releasing, detecting and responding to minimal diffuse-able banner particles. The limit of microscopic organisms to give and carry on as a get-together for social correspondences like a multi-cell animal has given basic favorable circumstances to microbes in have colonization, plan of bio-films, guard against contenders, and acclimation to developing circumstances. Basically, various QS-controlled activities have been related with the hurtfulness and pathogenic capacity of microscopic organisms

Daniel [21]

Answer:

Trophic level

Consumer

Producer

Explanation:

All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.

A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.

Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.

In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.
