Answer:
B) wastewater
Explanation:
all the waste water that goes down our sinks, out of the shower, from our washing machines and even from our toilets. Blackwater – waste water that comes from our toilets. Greywater – waste water that comes from our sinks, laundries, showers and baths.
The answer is; right atrium, pulmonary arteries, pulmonary veins, left ventricle, aorta
Deoxygenated blood from the tissues flows into the heart through the vena cava vein. The blood is pumped by the right ventricle to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs and flows back to the heart through the pulmonary vein. The heart (left ventricle) then pumps the oxygenated blood to tissues through the aorta.
Answer:
Prokaryotic cell-- no organelles, no membrane.
Eukaryotic cell -- Have organelles and membrane.
Explanation:
For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.
Answer: Option C.
Explanation:
The bird's lung are said as more efficient than a human or mammals.
The bird's are having small lungs with nine air sacs playing an important role in respiration.The air sacs allows a unidirectional flow of air inside the lungs while in human the air flow takes place in bidirectional. Unidirectional flow results in the flow of fresh air along with high oxygen content in bird's lung. So, there is more oxygen available to diffuse into the blood in bird lungs.
Hence, the correct option is C.
