Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.
In aplastic anemia, then lab result will be decreased in all blood component( white blood cells, red blood cells, and thrombocyte).
Aplastic anemia is caused by the bone marrow failure. Bone marrow is the place that produces blood cells, so the decrease wouldn't be in the red blood cell only, but in other blood cells too. There shouldn't be any iron deficiency or decreases in the mean corpuscular volume
