A negative feedback mechanism tries to negate changes so as to restore the variations that occurs in the value of a parameter or system.
<h3>What is Negative feedback?</h3>
This is known to be a method that tend to reverses any kind of movement or deviation from the set point and it then keeps the body parameters to its normal range.

Answer:
Fishes have a very particular respiratory system, which manages to extract the dissolved air from the water. They do it thanks to the gills, membranes located on the sides of their body. When the animal opens and closes its mouth, the liquid enters its interior through them and that is when the blood vessels absorb the necessary oxygen. If the water has toxic components or dirt, there will not be the necessary amount of oxygen.
Explanation:
Fishes obtain the oxygen they need from the water through the gills: membranous structures supported in turn by cartilaginous or bone structures. The gill surfaces are very wide, and respiratory gases are exchanged between blood and water as it flows over them. The fish takes water through its mouth and, through a complex process, releases the water through the lids, previously passing through the lamellae, where oxygen is captured. If the water has toxic components or dirt, there won’t be the necessary amount of oxygen, there would be impurities that limit oxygen. Pollution causes the loss of oxygen. Efficient oxygen absorption from water (as gills do) is essential for active organisms in the aquatic environment. Fishes promote gas exchange by ventilating the gill surfaces, either by actively pumping water through the gills, or by continuously swimming with their mouths open. In the end, the fish die because they cannot find what they need to live.
Answer:
Option C. As microscopes became more powerful, scientists could see additional structures and functions within the cell.
Explanation:
Light microscope is also called optical microscope which is used to see very small objects which can't be seen through naked eyes. The magnification power of light microscope is 1000x which means light microscope show the object 1000 times greater than its original size. Due to this magnification power, scientists are able to see many new features of the cell which cannot be seen with ordinary microscope.
Answer:
The correct answer is glands.
Explanation:
It is known that brain monitors movement, therefore, one can definitely correlate movement of muscles with the brain that comprises the role of sensory and motor neurons. When a stimulus is obtained by the sensory organs, it is transmitted by the sensory neuron to the brain and from their information is further conducted to the effector organs like muscles by the motor neuron. The glands are the group of cells, which takes part in the secretions when instigated by any particular hormone.
