Answer: B. right atrium --> right ventricle --> left atrium --> left ventricle
Explanation: Deoxygenated blood enters the superior vena cava and inferior vena cava and collects it on the right atrium. It is then pumped up through a valve and enters the right ventricle. Then it is transported by the pulmonary artery to the lungs to become oxygen rich blood. From the lungs oxygenated blood enters into the pulmonary vein and back into the heart and goes inside the left atrium. The blood is pumped again through a valve going to the left ventricle and transported to the body through the aorta which distributes oxygen rich blood.

Vanilla, saffron, patchouli. For centuries, spices and flavorings like these have come from exotic plants growing in remote places like the jungles of Mexico or the terraced hillsides of Madagascar. Some were highly prized along ancient trading routes like the Silk Road.
Now a powerful form of genetic engineering could revolutionize the production of some of the most sought-after flavors and fragrances. Rather than being extracted from plants, they are being made by genetically modified yeast or other micro-organisms cultured in huge industrial vats.
Testosterone is a steroid. Its physiological functions are:
Determines the the gender of a developing embryo
Development of reproductive organs and the prostrate gland in males
Responsible for secondary sexual characteristics in males such as deeper pitch, increased muscle bulk, hair on the upper lip
Regulates normal sperm development
Another is cholesterol. Physiological functions are:
Helps maintain the structure of cells and vessels improving overall health and function in the body.
Percursor to important sex hormones such as testosterone and estrogen.
Used as an insulator around nerves and is absolutely essential for brain function.
Precursor to Vitamin D, which supports a healthy immune and nervous system
Answer: Genetic Tolerance
The answer is Genetic Tolerance because the definition of it is "Genetic resistance (or genetic tolerance) refers to the ability of certain organisms to endure environmental conditions that are extremely stressful or lethal to non-adapted individuals of the same species ."
