Answer: Capillaries pass oxygen and waste between blood and cells.

Explanation: Capillaries are very thin-walled tubes that connect the arteries to the veins. The walls of these tubes are only one cell thick. Capillaries are found everywhere in the body. These thin tubes allow the food, oxygen, and waste to move between the bloodstream and cells. Waste products pass into capillaries and are carried by the veins to be disposed of in other parts of the body. Capillaries are the only blood vessels thin enough for materials to pass back and forth between cells and blood.

  • atoms
  • Electrons
  • shells
  • Valence electrons
  • Electron distribution
  • Molecules
  • Basic atoms
  • Charge distribution
  • Interact with other molecules electron
  • Harm living organisms

Atoms are composed of electrons. These electrons are arranged in shells. The number of valence electrons (outermost shell electrons) determine the kind of bonds that can be formed in a molecule.

In a molecule, charges are distributed in a unique way and the charge distribution in a molecule determines how the molecule interacts with other molecules. Different molecules can be made by arranging the same basic atoms in different ways.

Harmful substances can be formed when atoms of elements combine in new ways in the environment.

Alexxandr [17]

Answer:

Their answer about the location or function of the cells.

Explanation:

Since there are no options to select as the answer, i will just try my best to list a couple of them.

Langerhans Cells are from the family of cells named "Dendritic Cells" because of their tree like shapes. They can be found on parts of our body that come into contact with foreign environments or particles, such as skin, on the inside of our mouth, nose and stomach etc.

The nursing instructor could evaluate the students' knowledge by asking them where Langerhans Cells are located in our body, on which layer of our skin they can be found or what their primary functions are.

I hope this answer helps.
