Yes. Indirectly, through plants. Without plants using photosynthesis, and therefore, creating oxygen, we wouldn't have enough breathable air.

Select the correct partial path below. this path is part of the complete blood flow pathway. you should be able to trace flow st
olasank [31]

The right answer is: aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the tricuspid valve.

The blood pathway is divided into two circuits, both beginning and ending in the heart.

- Systemic circulation (or general circulation, or "circulation")

It begins in the left ventricle, which through an artery distributes oxygenated blood to organs. Then the blood returns to the right heart (right atrium) through the cellar veins.

Each organ has an afferent vessel, supplying blood, and an efferent vessel carrying non-oxygenated blood.

- The pulmonary circulation (or "small circulation")

It begins in the right ventricle, from where the pulmonary artery sends blood without hematosis to a single organ, the lung. The blood is then oxygenated and returns to the left heart (left atrium) by the pulmonary veins.

What evidence can be examined when determining common ancestry amongst hominids?
mars1129 [50]

We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.
