Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charge
Answer:
The correct answer is between the arachnoid and the pia. Thus option 'a' is correct.
Explanation:
Subarachnoid hemorrhage is the bleeding in the brain more precisely in the subarachnoid space-the space between the arachnoid and the pia matter surrounding the brain.
The layers that surround the brain termed as meninges of the brain of the brain include:
1) Dura matter the outermost layer close to the skull.
2)Arachnoid matter.
3) Pia matter, the innermost layer that is in contact with the brain.
A subarachnoid hemorrhage can occur due to many causes such as an accident , ruptured aneurysm, e.t.c. It is a life threatening condition and is accompanied with stroke.
The environmental benefit of the leaf canopy of a tree slowing down the impact of raindrops and the root system absorbing water and holding soil in place would be that the water erosion of soil would be minimized.
The washing away of topsoil by water is termed water erosion. This event has a number of impacts on the ecosystem, including:
- reduced agricultural yields
- damages to infrastructures such as roads
- washing away into nearby water bodies can cause eutrophication
- water quality of nearby water bodies becomes impacted negatively
The leaf canopies of trees prevent raindrops from having maximum impact on soil structure while the roots of trees absorb water and also holds soil structure together to limit water erosion of the soil. This will in turn prevent negative consequences to the environment.
