Explanation:
The potato, bacteria and a human is alike in the way that they all are made up of cells. The correct option is B.
What is a cell?Cells are the fundamental cornerstones of all life. Gazillions of cells make up the human body.
They support the body's framework, absorb nutrients from food, convert those calories into energy, and perform specialized functions.
The cell, first discovered by Robert Hooke in 1665, has a rich and interesting history that has led to many of today's scientific advances.
Cell theory is a biological theory first proposed in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Thus, the correct option is B.

The respiratory center is medulla oblongata. It is involved in minute to minute control breathing.
What parts are involved in the brain stem ?
Brain stem is made up of pons and the medulla oblongata.
The apneustic and the pnuemotaxic centers of pons work together to just control rate of the breathing. In that the medulla just sends the signals to muscles that just initiate the inspiration and the expiration and just controls the nonrespiratory in the air movement of the reflexes like coughing and sneezing.
The cerebellum is well known to just be the part of neuronal circuitry that is just activated in the respiratory challenges that are such as the hunger for the air but are not been made to be involved in control of the spontaneous and the unobstructed breathing .

Answer:
there more tissues or more organs in your body explain your reasoning
Explanation:
Each organ is made up of several different types of tissue. Therefore, for every organ in the body, there are many more tissues.
Answer: Venn diagram of exocytosis , diffusion , endocytosis , osmosis is
described below.
Explanation:
Exocytosis: refers to the process by which the contents of a cell are released to the exterior environment through fusion of the vacuole membrane with the cell membrane.
Endocytosis: refers to the process in which cells take the material from outside the cell by taking in the vesicle. These materials serve as nutrients and pathogens which help cell to fight against foreign diseases.
The common thing these two process have among them is
FlagellaPlasma MembraneCell divisionCytoplasmRibosomes chromosomesDiffusion: It is the process of movement of molecules from through a
semipermeable membrane from the region of higher concentration to lower concentration.
Osmosis: The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's fractionally permeable membrane.
The common thing these two process have among them is that equalizes the concentration of two solutions in mixture
