When the human body is responding to stress, the hormone adrenaline is released. A short time later, the body returns to normal. This is an example of how a human:

The human body fights an infection when a pathogen is detected. As a result, the pathogen stimulates the production of:

Some viruses can enter cells by first attaching to the cell membrane. The flu virus targets and attaches to the cells of the nose and mouth. The hepatitis virus targets only specific cells of the liver.

Most people who get vaccinated develop immunity to the disease. Explain why the contents of the vaccine usually do not cause people to get sick.

Anticancer Vaccines Become Personalized

Researchers are investigating a personalized approach to create an anticancer vaccine from a patient’s own tumor cells. Some white blood cells are removed and grown with proteins unique to these cancer cells. The patient’s white blood cells are changed by incorporating these proteins from the cancer cells. These altered blood cells can now work as a cancer vaccine. The cancer vaccine is transferred into the patient, and it stimulates the immune system to attack the cancer cells.
The diagram below represents a process that involves an anticancer vaccine.

Required

Which characteristic is common to most types of cancer?

Experiments in mice show that a guardian gene that protects against type 1 diabetes can be altered by exposure to antibiotics during development. The exposure alters the gut bacteria, leading to a loss of the guardian gene’s protection. The loss of this protection most directly interferes with:

Jean-Baptiste Lamarck was a French naturalist who proposed the idea that modern-day organisms developed new characteristics through a process known as the inheritance of acquired traits. As more evidence became available, this theory was eventually replaced by Charles Darwin’s theory of evolution. This modification of scientific knowledge illustrates that:
