question 7
foreign cells that enter our body have unique cell surface proteins, known as ______, which stimulate our body’s defense to attack.
rh factors
antigens
topic: sec. 7.1
skill: knowledge
leukocytes
platelets
antibodies

Explanation:

Deoxyhemoglobin is hemoglobin without oxygen bound to it. It is found in blood returning from tissues that have used oxygen, such as blood flowing from abdominal organs. It is in red - blood cells, has a darker color than oxyhemoglobin, and forms in areas with low oxygen concentration. For the second question, foreign cells have antigens on their surface which trigger the body's immune response. Rh factors are a type of antigen but not the most general term for foreign - cell surface proteins that trigger defense. Leukocytes are white blood cells, platelets are involved in blood clotting, and antibodies are produced by the immune system in response to antigens.

Answer:

Question 1: This type of hemoglobin would be found in blood flowing from an abdominal organ of the body.
Question 2: antigens
