In biological hierarchy, the levels of organization of the human body from simplest to most complex are: cells (the basic building block), tissues (groups of similar cells), organs (made up of different tissues), and organ systems (multiple organs working together). So, the correct answer to the student's question is (b).
In the biological hierarchy, the levels of organization in the human body typically increase in complexity. The simplest level is the cell, which is the basic building block of life. Groups of similar cells form a tissue, providing a specific function. Different tissues combine to form an organ, such as the heart or brain. Then, multiple organs that work together make up an organ system, like the digestive or nervous system. Therefore, the correct answer in order from simplest to most complex is (b) cells, tissues, organs, and organ systems.

life processes
produce salt-filled sweat to get rid of pathogens at the site
initiate cell division
protect against UV light
the answer is actually to initiate cell division i just took the test and missed it because i clicked minimize the flow of blood to site hope this helps :)
Answer:
Answer:
brush border cells....!!
The simple cuboidal cells of the proximal tubule are referred to as Proximal Convoluted Tubule (PCT) cells.
They have a distinct feature of having prominent microvilli on their luminal surface that forms a brush border.
These microvilli contribute to creating a large surface area which facilitates the maximization of the absorption and secretion of solutes including Na+, Cl¯, glucose, among others - a key function of this portion of the nephron.
These cells are responsible for the active transport of ions across their membranes and hence they possess a high concentration of mitochondria to produce sufficient ATP.
The PCT cells, forming a simple cuboidal epithelium, are active in secretion and absorption of molecules.
They are observed in the lining of the kidney tubules and are critical to the kidney's filtration function.
