A) 2MgCl2 + H2O B) 2MgCl2 + 2H2O C) MgCl2 + H2O D) MgCl2 + 2H2O Answer: D) MgCl2 + 2H2O Question: Which of the following is the collagen-rich material that connects muscles to bones? A) Tendon B) Ligament C) Reticular Tissue D) Areolar Tissue Answer: A) Tendon Question: Which of the following is the function of the spleen in a healthy adult human? A) It stores bile produced in the liver B) It synthesizes platelets C) It degrades aged red blood cells D) It is a vestigial organ Answer: C) It degrades aged red blood cells Question: Which of the following describes the action of histamine as a response to a bee sting? A) Histamine dilates blood vessels, which increases blood flow to the area B) Histamine degrades antigens through its catalytic activity C) Pathogens become trapped in histamine and are unable to infect the body D) Histamine triggers the release of the protein interferon Answer: A) Histamine dilates blood vessels, which increases blood flow to the area Question: Which of the following best explains why RNA inside a cell is almost never found as a single-stranded molecule? A) Alleles for genes are found in pairs, so their RNAs also pair up B) RNA normally exists with its complementary strand in a double helix C) RNA and DNA form hybrid pairs for all transcribing parts of the chromosome D) Short stretches of complementary sequences can cause RNA to fold back on itself Answer: D) Short stretches of complementary sequences can cause RNA to fold back on itself Question: Which of the following occurs when the diaphragm contracts? A) The thoracic cavity decreases in volume B) The thoracic cavity increases in volume C) The abdominal cavity increases in volume D) The abdominal cavity decreases in volume Answer: B) The thoracic cavity increases in volume Question: In a double circulation system, which of the following describes a possible pathway of blood flow through the pulmonary circuit? A) Oxygenated blood flows from the heart to the lungs B) Deoxygenated blood flows from the heart to the lungs C) Oxygenated blood flows from the lungs to the body D) Deoxygenated blood flows from the lungs to the heart Answer: B) Deoxygenated blood flows from the heart to the lungs This Is Helpful For: * Pre-nursing students preparing for the ATI TEAS 7 exam * Students applying to nursing school * Anyone who wants to study more efficiently with complete solutions I hope this helps you feel more confident as you prepare for your TEAS exam.
