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.

Fiesta28 [93]

Answer:

The correct answer is - Grant's research on finches on the Galapagos islands.

Explanation:

Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.

It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.
