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 answer is B) arachnoid granulations
Explanation:
Arachnoid Mater and CSF Circulation:
- The arachnoid is the middle layer of the meninges which are the membranes covering the brain.
- The arachnoid is characterized by the spider web like projections that extend between it and the pia mater (outer membrane of the meninges).
- These projections are located in the subarachnoid space (space below the arachnoid). These projections contain the circulating cerebrospinal fluid or CSF.
- The arachnoid extends into the dural sinuses through the arachnoid granulations in which the CSF is filtered and added to the blood for drainage from the brain.
Answer:
summer would be colder or cooler for a bit, then drastically change and melt ice and raise sea levels, potentially ending the world. Winter would destroy crops because the cold would be too harsh for our ecosystem and would last a lot longer, about 6 months in fact!
