Ions have positive charges when their atoms lose electrons to become stable. Ions have negative charges when their atoms gain elcetrons to become stable.

Answer:
Front
Explanation:
When two air masses collide, a front is formed. The two most common types of fronts are cold fronts and warm fronts.
Cold fronts are formed by the advance of cold continental polar or continental arctic air towards the south. The colder air wedges underneath the warmer air mass to the south and causes it to rise, forming a storm front.
A warm front is the pushing action done by an advancing mass of maritime tropical warm and moist air that pushes a colder air mass out of the way by rising on top of it gradually and moving it away slowly. This causes an extensive cloud front of light rains.
Answer:
Conditions at the base of a glacier increase glacial flow velocity -
Steeper slope
Smooth rock / glacier contact
Colder basal water temperature.
Explanation:
Steeper slope and smooth rock/glacier contact will increase glacial flow velocity because higher the steepness higher the velocity and smoothness will apply less friction.
Due to decrease in ice thickness the load at the bottom of the glacier will decrease, and we know that the glacier flows under the load of itself, so lesser the load lesser the velocity.
Colder basal water temperature will generate less amount of melt as compared to warmer basal water temperature, so in colder condition, glacial flow velocity will not be increased.
Answer:
Corteza renal, médula renal y pelvis renal.
Explicación:
Hay tres regiones principales del riñón, es decir, corteza renal, médula renal y pelvis renal. La corteza renal es la parte externa del riñón que se compone de glomérulos y túbulos contorneados. La corteza renal es responsable de la protección de las estructuras internas del riñón. La médula renal es la parte más interna del riñón que se divide en pirámides renales. La médula renal es responsable de la regulación de la concentración de orina. La pelvis renal es la región donde se unen los dos o tres cálices principales. La pelvis renal actúa como un embudo para la orina que fluye hacia el uréter.
The journals were based upon the field diaries that explorers were required to keep by the Colonial Office. The explorers' field diaries and journals were also of vital importance for the information they contained about possible economic benefits that could be derived from the land.
