Answer:
option A
Explanation:
because plants give oxygen
Circulation of the blood is crucial in the body since it helps in supply of nutrients and oxygen to all parts of the body. It is these nutrients and oxygen that are key in the activities of a cell or a tissue without which the cells wont efficiently carry out their functions.The inability of the body to supply blood and oxygen to the body cells as required is known as hyperfusion. Hyperfusion is caused by inadequate perfusion of the body tissues and thus resulting to inefficient supply of nutrients and oxygen gas to the body cells and tissues.
Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. Rivers can create a significant amount of erosion over time. They break up particles along the river bottom and carry them downstream. One example of river erosion is the Grand Canyon which was formed by the Colorado River. Ocean waves can cause the coastline to erode. The shear energy and force of the waves causes pieces of rock and coastline to break off changing the coastline over time. Large floods can cause erosion to happen very quickly acting like powerful rivers.
Answer:
The correct answer is both are produced in red bone marrow.red blood cells transport oxygen while white blood cells protect the body against disease.
Explanation:
Red blood cells or RBC contain hemoglobin protein that helps in the transport of oxygen and carbon dioxide to and from our body.
Where as white blood cells provide defence to our body against various invaded pathogens.There are many types of White blood cells such as eosinophyll, basophyll,neutrophyll,monocyte and lymphocyte.
Both RBC and WBC are generated from red bone marrow.
