What type of glial cell acts locally to maintain normal electrolyte composition of the cerebrospinal fluid?

Biology
1 answer:
nikitadnepr [17]3 years ago
7 0

Answer:

Astrocytes

Explanation:

Astrocytes are specialized glial cells found in the brain and spinal cord, they are responsible for maintaining the electrolytic composition of the cerebrospinal fluid, induce the formation of the blood-brain barrier and act as a support and guide for neurons during migration. They keep the ionic composition of the extracellular fluid of the central nervous system through the water channels, Aquaporin-4 (AQP4) and K channels, located in the pedicle processes of the astrocytes in the perivascular space, these cells exchange K and water in said perivascular medium away from the neurons. Astrocytes selectively edematize during hypotonic stress, while neurons do not.

What happens to the temperature of a sample of matter as it changes from a liquid to a gas?
irina1246 [14]
All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. You have to use all of your tricks when that happens. To create a solid, you might have to decrease the temperature by a huge amount and then add pressure. For example, oxygen (O2) will solidify at -361.8 degrees Fahrenheit (-218.8 degrees Celsius) at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased. i think

How do ocean currents affect temperature? Check all that apply
zlopas [31]

Answer:

Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.They carry cold water from the poles to the equator and cool air over land.  They move warm water from the equator to the poles and heat air over land.

Explanation:

They carry cold water from the poles to the equator and cool air over land.  They move warm water from the equator to the poles and heat air over land.

Which organisms have the least amount of stored energy in an ecological pyramid
Alenkinab [10]
<h2>Answer</h2>

Tertiary Consumers get least amount of the energy.

<h2>Explanation</h2>

In an ecological pyramid less energy is available to organisms in the upper level because each organism releases some of the chemical energy as food and to the air as thermal energy .Therefore primary consumers get almost 10% of autotrophs prduced energy. The second consumers in the pyramid get 1% from primary consumer. In the case of tertiary consumers, they get only 0.1%. Hence the top consumer of a food pyramid receives the least energy.
