Answer:
fully oxygenated blood returning to the amphibian heart can undergo additional pumping to reach higher pressures.
Explanation:
Fishes have a two-chambered heart with one atrium and one ventricle. The blood is pumped from the atrium into the ventricle. Ventricle pumps blood into a single circuit of blood vessels. Blood is oxygenated as it passes through capillaries in the gills. As blood circulates through the gill capillaries, it has low blood pressure and therefore, is delivered very slowly to the other organs.
The amphibian heart has two atria and one ventricle. A sinus venosus collects oxygen-poor blood and pumps it into the right atrium. Oxygenated blood from the lungs passes directly into the left atrium. The left atrium pumps the oxygen-rich blood into the arteries that conduct it to the various tissues of the body. Therefore, a three-chambered heart in reptiles allows the delivery of oxygenated blood with high blood pressure.
Answer:
It think it is the third option, since osmosis is not passive.
Explanation:
Cellular respiration and photosynthesis are complementary processes because they use each others' products and reactants.
Photosynthesis' products are cell respiration's reactants; likewise, cell respiration's products are photosynthesis' reactants.
Also, photosynthesis is known to take away carbon dioxide from the air and put in oxygen while cellular respiration does the opposite, putting in carbon dioxide while taking away oxygen.
The herpes virus infects the humans to cause chickenpox disease. The virus during its stage of causing infection, it spreads through the epidermal cells by infecting them. This causes the typical rash on skin that is seen in chickenpox. The virus then enters that sensory nerves present on the ski and travels along the length of the neurons to the sensory dorsal-root ganglia adjacent to the spinal cord. Here the virus stays in an inactive stage.
