Single-celled pond organisms have contractile vacuoles that maintain water balance within each cell. This is a an example of what scientific principle?

Answers

Answer 1

Answer:

The correct answer is homeostasis.

Explanation:

A self-regulating procedure taking place within an organism, which permits them to sustain a stable internal condition level is termed as homeostasis. In case, if an organism fails to sustain homeostatic balance, the eventual result would be death. Water balance, temperature, salt concentration, and pH are some of the several internal conditions, which are required to maintain comparatively stability.

Some of the single-celled pond organisms like paramecium comprise contractile vacuoles, which remove additional water out of the cell. As water balance is a part of sustaining homeostatic balance for an organism, thus one can study homeostasis by witnessing the modifications within the contractile vacuole when the species is placed in distinct solutions.

Explanation:

Answer:

Plant cells need turgor pressure to maintain their rigidity and sturdiness. This is what gives a plant the ability to grow and stand tall. ... The turgor pressure provided by osmosis in a hypotonic solution pushes outward on the plant cell wall, which is just what the plant cell needs to maintain its structure.

Which of the following senses is mediated by mechanoreceptors?
A. Sight
B. Taste
C. Hearing
D. Smell​

Answers

Hearing is the sense mediated by mechanoreceptors.

Mechanoreceptors are a type of receptors involved in the perception of:

Changes in the temperature.Movement.Vibrations or sounds.Pressure.

One of the senses that is directly related to these receptors is hearing because this sense involves the perception of sounds through vibration or waves.

In this way, every time there is a sound the mechanoreceptors located in the ear perceive this sound and translate these waves into neural signs, which is necessary for the hearing process.
