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.
<span>This would be an example of a mutation, because the changing of allele frequencies would be a change within the gene itself, which would be a mutation in the DNA. This is evidenced by the fact that there is now a form of human resistance to malaria, due to changes within human DNA itself.</span>
Answer:
Hydrogen Bonding. A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons
Explanation:
Answer:
What does a linear velocity graph tell us?
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
What is an acceleration time graph?
A graph that shows acceleration plotted against time for a particle moving in a straight line. ... The acceleration-time graph is the graph y=a(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards.
graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.
Explanation:
I think the answer is B because it use mechanical power and convert it into electricity
