The answer is the second one (macrophages): macrophages move to infection sites where they ingest and digest infectious microorganisms.

Explanation for each option:

  • Erythrocytes: Incorrect. Erythrocytes, or red blood cells, are primarily responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation. They do not play a role in ingesting and digesting infectious microorganisms.
  • Macrophages: Correct. Macrophages are a type of white blood cell that moves to infection sites and engulfs and digests pathogens and cellular debris. They are an essential part of the immune system's response to infection.
  • Fat cells: Incorrect. Fat cells, or adipocytes, store energy in the form of fat and do not have a role in the immune response to infections.
  • Epithelial cells: Incorrect. Epithelial cells form the lining of surfaces and cavities in the body, providing a barrier and protective function, but they do not ingest and digest infectious microorganisms.
  • Neurons: Incorrect. Neurons are nerve cells responsible for transmitting signals throughout the nervous system. They do not participate in the immune response to infections.

Summary: Macrophages are the type of cells that move to infection sites where they ingest and digest infectious microorganisms.

Suppose a crime scene investigator uncovers a partial skeleton and identifies a bone as a human ulna (the ulna is one of two bones in the forearm and extends from elbow to wrist). If the length of the bone is 12 in ., estimate the height of the person before death (use your equation from question 7). (Show your work!) Would you expect this person to be male or female? Explain the reason for your conclusion.

Describe what is misleading in the following visual display of data. Choose the correct answer below. A. The bars are not scaled proportionately in terms of the data they represent. B. The images in front of or behind each bar make it look as though the bars are taller than they really are. C. The wrong impression has been created about how the data are changing because equally spaced intervals are not used on the horizontal axis. D. The scale of the vertical axis makes the differences in bar height look larger than they really are.
