The term "You are what you eat" was coined due to the effects of the content of the food we ingest on the rest of our organism.

Food comes in an endless number of options, each of which contains numerous molecular compounds of varying kinds. Every molecular compound that we ingest through the food that we eat can have distinct effects on the body, some of these compounds include:

Macromolecules are a class of molecules that encompass many others. Proteins and lipids are just some of the examples mentioned that fall within the class of macromolecules. Some macromolecules can be good for the body, such as proteins, whilst others can cause some negative effects as is the case with lipids.

Lipids are vital for the proper functioning of the body. Lipids provide a source of reserve energy and can regulate hormones, among other important functions. However, lipids can also be harmful to your health. Lipids provide reserve energy by being stored as fat. Excessive consumption of lipids can cause numerous health problems.

Carbohydrates are at the same level as lipids in terms of their effect on the body. Carbohydrates are sugars, which are necessary to include in a healthy diet, however, excessive consumption of carbohydrates can cause health issues ranging from diabetes to pancreatic failure.

Proteins are amongst the most essential macromolecules for the human body. They provide a variety of functions which include:

among many others. This, along with nucleic acids are a prime example of "you are what you eat" in that those who consume more of these (coupled of course with proper exercise) tend to be healthier individuals.

Answer:

The hormone erythropoietin regulates enthrocyte production, which is produced in the kidneys.

Explanation:

Bone marrow is the body organ responsible for controlling erythrocyte (red blood cell) synthesis.

The process of erythropoiesis, which occurs largely in the bone marrow, produces erythrocytes. Hematopoietic stem cells, which can differentiate and develop into several types of blood cells, including erythrocytes, are found in the bone marrow.

The hormone erythropoietin (EPO), which is produced and secreted by the kidneys in response to low oxygen levels in the body, regulates the formation and release of erythrocytes. EPO stimulates the formation of erythrocytes in the bone marrow, maintaining an adequate supply of oxygen-carrying red blood cells in the bloodstream.

The constant movement of particles when seen under a microscope is a very common observation known as Brownian motion.

All particles are made of atoms. Atoms are comprised of three components:

the first two comprise the core of an atom, surrounded by a cloud of electrons.

Though much too small to be seen without aid, these atoms do indeed possess mass and are capable of colliding with one another. Particles constantly collide with one another and are bounced in the opposing direction, over and over again. This is precisely what we observe under the microscope as particles bouncing around and is referred to as Brownian motion.
