The right ventricle pumps blood to the 1) right atrium. 2) pulmonary veins. 3) pulmonary artery. 4) aorta.In which structure is the oxygen content highest? 1) Pulmonary veins 2) Venae cavae 3) Right ventricle 4) Pulmonary arterythe primary function of triglycerides in the body and explain how their structure supports this function. __3. Freeways may provide an effective geographic isolating mechanism for some slow-moving animals. Why are such artificial barriers not likely to result in complete speciation? 4. A common definition of species states that a species is a group of organisms that can breed and produce fertile offspring in nature. A mule is a sterile offspring of a horse and a donkey.By the definition above, do a horse and donkey belong to the same species? Explain. 5. Define homeobox genes and give an example. 6. Define epigenetics and briefly explain the 2 examples of this that we studied in class. 7. What are obesogens?Explain THREE concerns scientists have about these chemicals.Place the following steps in the renin-angiotensin -aldosterone system (RAAS) in the order in which they occur. 1. Renin is released. 2. Cardiac output falls. 3. Vasoconstriction occurs. 4. Angiotensinogin is activated. 5. Angiotensin 1 is converted to angiotensin 2PREV 172173174175176177178179180 NEXT
