Answer:

The correct answers are option C and D.

Explanation:

The three basic sayings of the cell theory are that all the living components are formed of cells, the cells are the basic unit of all living species, and all the cells originate from the preexisting cells. All the living things, that is, from microscopic species to the largest one like whale, are all formed of cells. These cells can differ broadly, however, all the living components are formed of cells.

The cells in a living being cannot be further dissociated into any more level. Like the atoms and matter, the cells and living species are associated, that is, at their most basic level, the living species are formed of cells.

Create your own cartoon of a negative feedback system of the respiratory system

bekas [8.4K]

Answer:

Negative Feed Back system - " Some times an organ stops or interrupts a process or function in order to stabilize its self and the body, mainly the output or product of the process is lessened in order to control the situation such mechanism is known as negative feed back system."

Explanation:

Negative feedback system in Lungs

Now in lungs, the respiratory system maintains the normal partial pressure of the arterial oxygen and Carbon dioxide. As the partial pressure if exerted by them has a very high influence on the blood pH and can cause imbalance in the blood pH. So for this reason the negative feed back system is present.

As the body sends the message to the controlling hub of human body and then it starts the process of stabilizing the whole system back to normal by rearrangements of components or parts, along with secretion of some chemicals in the human body.

Moreover a sketch is drawn which shows the feedback mechanism in a more simple way.
